00:00:00Attention! Attention! Residents of all countries and cities of the world!

00:00:05A massive asteroid is approaching the Earth!

00:00:07Now its speed is several times greater than the speed of sound,

00:00:11and each day, it accelerates even more!

00:00:13Once it enters our solar system, it will fly past Uranus, Saturn, Jupiter, and Mars.

00:00:19The gravitational fields of these planets will also accelerate the asteroid,

00:00:24and our planet will be the final destination!

00:00:27A collision is inevitable.

00:00:29According to scientists, a meteorite the size of Mount Everest can destroy the entire planet.

00:00:35The disaster will happen in 350 days.

00:00:38There's panic in the streets. People buy and build bunkers.

00:00:42Scientists and astronomers from all over the world were assembled to find a solution.

00:00:47The only way to avoid the collision is to destroy the space object.

00:00:52Yeah, a powerful rocket can split an asteroid into hundreds of thousands of pieces.

00:00:57In this case, a meteor shower will hit the Earth,

00:01:00but it's better than the complete destruction of our home.

00:01:03In less than a year, people build several powerful rockets.

00:01:07Then, using the best telescopes in the world, astronomers create a unique guidance system.

00:01:13And now, we just have to wait for the asteroid to get into our solar system.

00:01:18All the people start moving to one continent with top-notch bunkers for everyone.

00:01:22The damage from the asteroid is impossible to predict,

00:01:26so it's better to hide people in one super-large safe place to wait out the collision.

00:01:31The moment has come. The asteroid passes by Uranus.

00:01:35The speed increases.

00:01:36Now, the colossal space object moves only ten times slower than the speed of light.

00:01:41Scientists launch rockets into the air.

00:01:44The asteroid flies past Saturn and destroys a part of its ring.

00:01:49The asteroid's trajectory is changing.

00:01:51It flies past other planets through a twisting path,

00:01:54picks up speed, and now heads towards the Earth.

00:01:58The rockets leave a long trail of fire behind and reach the speed of sound.

00:02:03They're getting closer to the asteroid.

00:02:05Near Mars, a collision happens.

00:02:07The rockets hit the target.

00:02:09The asteroid explodes and splits into millions of particles.

00:02:14All the pieces fly in different directions.

00:02:16The Earth is saved.

00:02:19At this moment, the Earth's satellites record a huge burst of energy.

00:02:23A small part of the asteroid is headed towards Earth.

00:02:26It's tiny, about the size of a grain of sand.

00:02:29But the explosion accelerated it,

00:02:31and now the grain of sand is flying towards the Earth at a speed of 185,000 miles per second,

00:02:39which is 99% of the speed of light.

00:02:42At this speed, the grain has almost the same destructive power that the entire asteroid had.

00:02:48It's approaching the Moon.

00:02:49A few more seconds, and the grain of sand will hit our planet.

00:02:53All the people are waiting with bated breath.

00:02:56The grain gets such incredible power because of the laws of physics.

00:03:00The greater the speed any object is, the more mass and energy it has.

00:03:04When the grain of sand reaches a speed close to the speed of light,

00:03:08its energy and mass begin to increase dramatically.

00:03:11You can't even see this tiny grain of sand,

00:03:14but inside, it has the mass of an entire continent.

00:03:18If the grain reaches the speed of light, its mass will be infinite.

00:03:22And then, a black hole will appear.

00:03:26In this case, all living and even inanimate things on the planet will disappear.

00:03:31Trees, seas, and oceans.

00:03:34All the cities, countries, and continents.

00:03:36Air, sound, atmosphere, any molecule of the Earth.

00:03:40Everything will be absorbed by the incredible gravitational force of the black hole.

00:03:45Then, when there is no trace of our planet, the hole will take over the Moon.

00:03:50The gravitational force will grow and absorb other planets of the solar system.

00:03:55Soon, it will reach the Sun.

00:03:57Our star will split into thousands of strips like spaghetti

00:04:01and will emit a tremendous amount of energy.

00:04:04This could trigger the birth of a second black hole.

00:04:07But, fortunately, we only have 99% of the speed of light, which changes everything.

00:04:13Also, no object that has mass can reach the speed of light.

00:04:17The grain of sand enters the Earth's atmosphere.

00:04:20From the outside, it looks like a blinding meteor that pierces the sky.

00:04:25The grain heats up, passing through the layers of the atmosphere.

00:04:29Clouds within a radius of 100 miles around are burning up.

00:04:33The sky becomes crystal clear.

00:04:35If you look at it in slow motion, you can see the air is ionized

00:04:40because the air molecules are split.

00:04:42In nature, this process occurs during lightning flashes.

00:04:46Our Sun also has ionizing energy and disinfects the air.

00:04:50The meteorite leaves an ozone hole behind it.

00:04:53So now, this place is not protected from space radiation and ultraviolet light.

00:04:59The grain of sand flies straight into the center of the Southern Ocean.

00:05:03The closest continent to the explosion is Antarctica.

00:05:06The air around it warms up and mixes with the cold temperature of the ocean, creating hurricanes.

00:05:13As soon as the grain approaches the ocean surface, the water starts boiling.

00:05:17The temperature and energy of the grain are so huge that the water evaporates.

00:05:22But the vapor molecules are instantly burned up.

00:05:25Thousands of gallons of water just disappeared from the face of the Earth.

00:05:29The grain flies down for the first few feet without touching the surface

00:05:33as the water evaporates before it.

00:05:36Then it falls into the ocean and creates a powerful explosion.

00:05:40Hundreds of millions of gallons of water foam and boil because of the hot temperature.

00:05:46The entire ocean within a radius of 100 miles is illuminated with a bright light.

00:05:52The ocean depths, where sunbeams have never been before,

00:05:55are almost as transparent as the water at the bottom of a pool.

00:05:59The wreckage of old sunken ships splits into atoms because of the powerful explosion.

00:06:05Unknown sea monsters and giant squids that live in the dark

00:06:08are afraid of the bright light and swim away.

00:06:11Then, finally, a grain of sand touches the seafloor and penetrates deep into the Earth's crust.

00:06:18If it reaches the Earth's core, the planet will most likely explode from a burst of incredible energy.

00:06:24Fortunately, this is not going to happen.

00:06:28The resistance of the ocean and the ground slows down the grain and takes its energy away.

00:06:33It provokes a slight shift of tectonic plates.

00:06:36And there's more to come.

00:06:38Huge waves form and spread throughout the ocean.

00:06:42The blast wave creates enormous tsunamis.

00:06:44Imagine throwing a small rock into a puddle.

00:06:47The same thing happens to the ocean.

00:06:49Huge waves are approaching the coastal cities.

00:06:52Fortunately, people were evacuated from there.

00:06:55But the damage caused by one grain of sand will cost hundreds of trillions of dollars.

00:07:01Houses are destroyed. Roads are flooded.

00:07:04After a while, it starts raining with hurricanes.

00:07:08Ocean water vaporized by the grain forms into huge storm clouds.

00:07:12The wind drives them to the continents.

00:07:15And then, after the tsunami, prolonged rain begins, flooding entire countries.

00:07:21Several days later, natural disasters are still here.

00:07:25The temperature of the southern ocean has increased by several degrees.

00:07:30The water is boiling at the collision site, melting the Antarctica glaciers.

00:07:34Millions of icebergs are melting away.

00:07:37So the water level of the world's oceans is rising.

00:07:40The edges of some continents go underwater forever.

00:07:44Thunder clouds reach the Sahara and other deserts.

00:07:47The shift of tectonic plates causes earthquakes on some continents.

00:07:52Volcanoes are awakening.

00:07:54The sky is filled with volcanic ash.

00:07:56It will take months for all the ashes to settle.

00:07:59In the beginning, it creates challenging conditions for life on Earth.

00:08:03Plants and all living things don't receive enough sunlight.

00:08:07In trees and seaweed, photosynthesis is disrupted.

00:08:11Oxygen production stops.

00:08:13It's getting harder to breathe.

00:08:15The air that has filled the planet's atmosphere is slowly running out.

00:08:20People have to adapt to new conditions.

00:08:23They build new cities both on the land and in the ocean.

00:08:26They create plantations with artificial lighting for photosynthesis production.

00:08:31Fortunately, all the problems end when the ash settles.

00:08:35Inside the volcanoes, there's hot magma flowing.

00:08:39It may come in handy as it's rich in chemical elements and minerals.

00:08:43Together with the ash, nutrients fall to the ground, and the soil is now well fertilized.

00:08:49Plants, trees, fruits, and vegetables grow incredibly fast and produce a lot of new oxygen.

00:08:56The Sahara is filled with blooming flowers now.

00:08:58And it looks more like a meadow with flowers, not a desert.

00:09:02The grain of sand just renewed the planet instead of destroying it.

00:09:07Hello and welcome to the Survive No Matter What Show.

00:09:11Today, our host, Alberto, will perform a crazy trick.

00:09:15Last year, he lived in a cave with a grizzly bear for two months and managed to survive.

00:09:21Do you remember how Alberto smeared himself with minced meat and jumped into a pool with piranhas?

00:09:26I hope you haven't forgotten how Alberto grilled a barbecue on an awakened volcano.

00:09:31Well, forget it.

00:09:32Today, Alberto will do the most dangerous and crazy trick in his life.

00:09:36Especially for you, dear viewers, he will get swallowed by a giant blue whale.

00:09:43Alberto goes to the North Atlantic.

00:09:45It's a vast area of water where you can meet blue whales and cachalots.

00:09:50He gets on a yacht and sails far from the shore.

00:09:53He's going to look for whales using echolocation and binoculars.

00:09:58A few days have passed.

00:10:00Alberto sits on board and studies the horizon.

00:10:03The sonar detects some movement.

00:10:05He looks toward the signal and sees a water fountain rising into the sky.

00:10:09It's a giant blue whale, the largest mammal on the planet.

00:10:13Yes, it's a mammal, not a fish.

00:10:16So, Alberto smears himself with oil to easily squeeze into the whale's throat.

00:10:21He takes an oxygen mask and jumps into the water.

00:10:26The blue whale opens its mouth and absorbs a massive amount of water.

00:10:30Its mouth is filled with whale bone.

00:10:32These are the bristles that replace teeth.

00:10:35They consist of keratin protein.

00:10:37People's hair and nails are made of it.

00:10:40The whale draws in water and then pushes it out.

00:10:43The bristles prevent small fish and plankton from leaving the mouth along with the liquid.

00:10:47Whale bone is like a filter.

00:10:50Alberto swims closer.

00:10:52The whale takes a sip.

00:10:54It absorbs several dozen gallons of water and sucks up Alberto.

00:10:58Our hero is inside the storm.

00:11:01The water splashes in different directions.

00:11:03And a giant tongue, the size of an elephant, throws Alberto on different sides.

00:11:08Alberto tries to get to the throat, but the water splashes back out.

00:11:12Alberto slides along the tongue to the mouth's exit.

00:11:16But the whale closes his mouth and he crashes into the whale bone.

00:11:20It's a little painful.

00:11:21A couple of bristles even fall off.

00:11:23The tongue wants to push him out, but Alberto manages to squeeze into its throat.

00:11:30But here, he meets a block.

00:11:32He can't go further because of the structure of the whale.

00:11:35This colossal animal's throat is tiny, the size of a fist.

00:11:39But it can stretch.

00:11:41Alberto had foreseen this.

00:11:43That's why he smeared himself with oil.

00:11:45He stretches out to his full height and jumps into the throat.

00:11:49Now our hero finds himself inside a narrow esophagus.

00:11:53He slides on it like a slide in a water park.

00:11:56Then his speed decreases.

00:11:58The space becomes narrower.

00:12:00Now Alberto is crawling forward with difficulty.

00:12:03It's very slippery here and Alberto can barely move.

00:12:07The esophagus contracts and pushes Alberto further.

00:12:11Now he's inside the stomach.

00:12:13It's dark, cramped, and smells awful.

00:12:16Alberto wants to light a match, but his pockets are entirely wet.

00:12:20And it's a bad idea to make a fire here.

00:12:23Firstly, there's almost no oxygen, which means no chance for a fire.

00:12:28Secondly, various chemical reactions occur inside the stomach, creating explosive gases.

00:12:34Alberto doesn't want that.

00:12:36He takes out a flashlight and examines the place.

00:12:39The walls of the stomach are narrow and constantly pulsating.

00:12:42Alberto can't stand up to his full height.

00:12:45He's knee-deep in some liquid.

00:12:47He sees skeletons of fish, shipwrecks, supermarket baskets, DVDs, a lamp, and a Moby Dick book around him.

00:12:55No, that's not true, as you're unlikely to find anything interesting inside a whale's stomach.

00:13:00Maybe a plastic bottle or some small squid.

00:13:04By the way, a cachalot, unlike a blue whale, has a wide and long throat.

00:13:09This allows it to swallow large prey whole.

00:13:12Technically, it can swallow a human with one sip.

00:13:17Anyway, you can find many exciting things in the cachalot's stomach.

00:13:21Once, this creature swallowed a giant squid whole.

00:13:24The length of these squids can reach 46 feet.

00:13:27That's the size of a small bus.

00:13:29But the cachalot managed to swallow such prey thanks to the flexible structure of the squid's body.

00:13:34Okay, now let's get back to Alberto.

00:13:37There's a terrible smell in the whale's stomach.

00:13:39Plankton and small fish are digested in gastric juice.

00:13:43And, wait, why does it hurt so much?

00:13:46Alberto feels the stomach juice splitting his suit.

00:13:50Alberto tries to get up, but it's too crowded in here.

00:13:53He hits the stomach walls with his hands, but nothing happens.

00:13:57The stomach narrows and squeezes Alberto more and more.

00:14:01The juice irritates his skin.

00:14:03Alberto shouts and waves his legs in different directions.

00:14:07He wants to cause a gag reflex, but it doesn't work.

00:14:11Alberto is desperate, and he doesn't know what to do.

00:14:14It seems that this is his last adventure.

00:14:17He closes his eyes and takes a deep breath.

00:14:20Stop! A deep breath! Precisely!

00:14:23Alberto opens the oxygen tank and fills the stomach with fresh air.

00:14:28Now the whale begins to bloat and is filled with gas.

00:14:32The stomach is throbbing. The juice is foaming.

00:14:35It seems a storm is coming.

00:14:37The walls contract so much that they squeeze Alberto out through the esophagus.

00:14:42Together with the remains of fish and juice, he moves forward.

00:14:46The esophagus is getting narrower.

00:14:48Alberto finds it hard to breathe, but he sees the light at the end of the tunnel.

00:14:52The whale spits him out.

00:14:54Alberto is alive!

00:14:56He's happy that he managed to escape such an adventure unharmed.

00:14:59He returns to the boat and sails to the shore.

00:15:02But, wait a minute.

00:15:04What's that swimming by right now?

00:15:06It's a cachalot! What a stroke of luck!

00:15:09Alberto dives into the water again.

00:15:11He's heading straight for the mouth of this huge animal.

00:15:14The cachalot absorbs water.

00:15:16Several fish and an octopus get there along with Alberto.

00:15:20The cachalot pushes him with its tongue in different directions and swallows all the prey.

00:15:25The road is wide enough and Alberto easily manages to get there.

00:15:29But there's another problem.

00:15:31Alberto is already in a very tight esophagus where he can hardly breathe.

00:15:35And he doesn't have an oxygen tank.

00:15:38Alberto feels like he's been wrapped tightly in duct tape.

00:15:41He can't do anything and there's no air here.

00:15:44He squeezes deep into the esophagus and feels that he is not alone here.

00:15:49In addition to the octopus, he feels the movements of large tentacles.

00:15:53Wow! It's a giant squid!

00:15:56And it seems it's still alive.

00:15:58Alberto shakes his whole body but can't change anything.

00:16:02He loses consciousness.

00:16:04The stomach walls are pressing on his face.

00:16:06At this point, Alberto bites it.

00:16:09An earthquake begins.

00:16:11All that lay in the stomach comes out.

00:16:13Finally, Alberto is outside.

00:16:16A colossal squid swims away as far as possible.

00:16:20It seems it hasn't understood what happened to it.

00:16:23Our hero climbs onto the yacht.

00:16:25He's the happiest person on the planet right now.

00:16:28He starts the engine and heads to the shore.

00:16:31You must understand that Alberto's story is purely hypothetical.

00:16:36Of course, in reality, a whale wouldn't be able to swallow a human.

00:16:40Reports that a person ended up in a whale's stomach are overgrown with myths and legends.

00:16:45Yes, there were cases when people got into their giant mouths.

00:16:49But they didn't go through the throat.

00:16:51One day, a diver got there.

00:16:53But he miraculously survived thanks to scuba diving equipment that helped him breathe.

00:16:58Another case occurred with people who were kayaking.

00:17:01When a humpback whale catches fish, it swims up to the surface with its mouth open.

00:17:06It's like a grid that rises from below.

00:17:09Those guys on the kayaks were too close and fell into the whale's mouth.

00:17:13Anyway, don't worry.

00:17:15A whale can't swallow you.

00:17:17It's impossible.

00:17:18But it is possible for a cachalot.

00:17:20The good news is that this is a rare animal.

00:17:23The probability of getting into its stomach is one in a billion.

00:17:27It's more likely that a meteorite will fall near you.

00:17:30Most people on Earth will never see a cachalot in real life.

00:17:33These animals swim worldwide in open oceans,

00:17:36but spend most of their time at a depth of about 10,000 feet.

00:17:40That's ten times the height of the Eiffel Tower.

00:17:43April 10, 1912.

00:17:45You're on the coast of the Atlantic Ocean in a small port town.

00:17:49Hundreds of people, and you among them, are going to board the huge majestic ship.

00:17:54It's three times as long as the Statue of Liberty is tall.

00:17:57The ship is considered the most advanced and unsinkable watercraft of its time.

00:18:02You can see hundreds of luxury cabin windows on its deck

00:18:05and the Titanic inscription on the magnificent iron hull.

00:18:10On this day, the famous superliner set off on its first, and last, voyage

00:18:15from Southampton to New York.

00:18:17But now, you'll see an alternate story.

00:18:22You can hear a crew member announcing the start of the Titanic's trip.

00:18:26The ship sails from Africa to Bermuda,

00:18:29and the cause of its catastrophe will not be an iceberg at all.

00:18:33For four days, Titanic sails through North Atlantic waters.

00:18:37The wind warms the ship so much that during the day,

00:18:40all the passengers sit inside the ship.

00:18:43In the evening, when a cool breeze descends on the ocean,

00:18:46all the people go up on deck to watch the beautiful red sunset.

00:18:50Midnight, April 15.

00:18:52You're sitting in your cabin reading a book.

00:18:54You're usually asleep at this time,

00:18:56but right now, you're just flipping through page after page.

00:19:00You close the book and look around the cabin.

00:19:02You feel like someone's watching you.

00:19:04You get up and break out into a cold sweat.

00:19:07An inexplicable feeling of anxiety permeates your body and causes goosebumps.

00:19:12You look out the cabin window where the ocean spray is banging the glass,

00:19:17but you can't see anything.

00:19:18There's a thick fog outside.

00:19:20You leave the cabin.

00:19:22In addition to you, several passengers also left their beds

00:19:25because of a heightened sense of danger.

00:19:28They greet you and ask what's wrong, but no one knows.

00:19:31You head to the stairs to go out on the deck to see the situation.

00:19:35At this point, the floor goes out from under your feet.

00:19:38A strong push makes you fall.

00:19:40A rumble reverberates through the Titanic.

00:19:43You get up and see more and more people going out from their cabins.

00:19:47You run up the stairs and meet a crew member.

00:19:49He doesn't tell you anything, but his eyes are wide with fear.

00:19:53You go up on deck and can hardly see anything.

00:19:56A thick, wet fog has settled over the ship.

00:19:59Several passengers are holding their heads as if they have a headache.

00:20:03You see the captain and ask him what happened.

00:20:06The captain admits that he has no idea where you are.

00:20:09You see a compass in his hand.

00:20:11The arrow turns in different directions.

00:20:13It's impossible to determine where exactly the ship is now.

00:20:17Interestingly, there was no such thing as the Bermuda Triangle before 1964,

00:20:22but the first reports of missing ships in this area

00:20:25date back to the middle of the 19th century.

00:20:28Another push.

00:20:29This time you've managed to stay on your feet.

00:20:31It felt like something big just hit the ship.

00:20:34You run to the railing at the edge of the deck and stare overboard.

00:20:37Through the white fog, you notice a huge shark fin.

00:20:41You haven't seen the full size of the shark,

00:20:43but from what you've seen, it must be as long as a train car.

00:20:47The shark swims away, but after a few seconds, you can see its fin again.

00:20:52It quickly approaches the ship and grabs the iron hull with its huge jaws.

00:20:57The deck is shaking.

00:20:58You can hear the grinding of metal.

00:21:00It seems this huge predator just made a hole in the hull.

00:21:04Only one creature on the planet can do this.

00:21:07The Megalodon!

00:21:09It's an ancient marine predator that measured almost 60 feet in length.

00:21:13Megalodon had no competition in the ocean.

00:21:16It was at the top of the food chain.

00:21:18It's believed the shark disappeared millions of years ago,

00:21:21but the ocean is only 5% explored.

00:21:24Here, it's alive and swimming in the mysterious waters of the Bermuda Triangle.

00:21:30Everyone aboard the ship is panicking.

00:21:32People from the lower decks are running upstairs.

00:21:35The Titanic slowly sinks and tilts to the side.

00:21:39Everyone goes to the lifeboats, but no one dares to get in them

00:21:42while the huge ancient monster is around.

00:21:45The ship's bow submerges under the water.

00:21:47You stand on the left side of the deck

00:21:49and see the Megalodon bite off pieces of the iron hull.

00:21:53You shout to the people in the stern section

00:21:56that the Megalodon is busy and they have time to evacuate.

00:21:59The first rescue boats with passengers go down on the water.

00:22:02Some passengers just jump overboard.

00:22:05Fortunately, the water is much warmer than the place where the Titanic actually sank.

00:22:10You put on a life jacket and jump too.

00:22:13The Megalodon attacks the ship and drags it deeper into the water.

00:22:17The smell of the Titanic's kitchen must have attracted it.

00:22:21You find yourself among the ship's flotsam and lifeboats.

00:22:24The fog's finally rising.

00:22:26The starry sky and the moon illuminate the sea's surface.

00:22:30People help you to climb on board a rescue boat.

00:22:33Everyone tries to sail as far away from the sinking ship as possible.

00:22:37You see the huge shark swimming around the Titanic.

00:22:40At this moment, something distracts it and the predator goes away.

00:22:44More than half of the ship is already under the surface.

00:22:47The second part looks like a candle sticking out of the water.

00:22:50The ocean is calm. The sky is clear and cloudless.

00:22:53There's no wind.

00:22:55From the side, you see a huge wave growing behind the Titanic.

00:22:59It's about 50 feet high, like a five-story building.

00:23:02It knocks the ship down as easily as if it was made of paper.

00:23:06The monster wave dissolves in the water as quickly and unexpectedly as it appeared.

00:23:12You've just witnessed a rogue wave.

00:23:15This phenomenon occurs all over the world.

00:23:18Enormous waves suddenly appear, demolish ships, and disappear without a trace.

00:23:23Scientists still can't determine their exact nature.

00:23:26But according to the most popular theory, these waves are formed by kinetic vampirism.

00:23:32Under certain natural conditions, waves accumulate and exchange kinetic energy.

00:23:37Among all the waves out there, there is one vampire wave that absorbs the energy of all the others.

00:23:44When a lot of energy is accumulated, a huge wave grows and splashes it all out.

00:23:49Some believe the frequent disappearance of ships in the Bermuda Triangle occurred because of rogue waves.

00:23:55The people on the boats calm down.

00:23:58Someone sends a flare into the sky.

00:24:00You look at the ocean and see the triangular fin of the Megalodon emerging from the water.

00:24:05It's the size of a sailboat, and it's coming your way!

00:24:09You row the oars as fast as you can.

00:24:11People are screaming and calling for help.

00:24:13There's no chance of escape.

00:24:15The legendary monster is getting closer and closer.

00:24:19The shark's head peeks out from under the surface.

00:24:22It opens its huge maw filled with hundreds of sharp teeth.

00:24:26Each of them is the size of your palm.

00:24:28The boat would fit entirely inside the shark's mouth.

00:24:32It can swallow you whole.

00:24:34The shark stops and closes its mouth at arm's length from the boat.

00:24:38You can see the water bubbling around you.

00:24:41From the ocean depths, several giant tentacles lash out and wrap around the Megalodon.

00:24:47They pull the shark down.

00:24:49You look over the side and see a purple glow with a black circle in the center.

00:24:54Someone on the boat notices it too.

00:24:56People start screaming.

00:24:58It's looking at us!

00:24:59A woman shouts.

00:25:01After a second, you get goosebumps, and a shiver runs through your entire body.

00:25:06This purple glow is something's eye.

00:25:09And the black circle is the pupil.

00:25:11The creature that is looking at you right now is so big that the boat seems like a grain of rice to it.

00:25:18It's the Kraken!

00:25:20The giant squid, an ancient monster that sank hundreds of ships,

00:25:24but whose existence has not been proven by anyone yet.

00:25:28Fortunately, the boat you're sitting in is too small to interest the Kraken.

00:25:33You can see its eye moving deeper away.

00:25:36Huge tentacles pull the struggling Megalodon into the depths.

00:25:40An hour passes, and another big superliner arrives at the wreck of the Titanic.

00:25:45All the passengers are rescued.

00:25:47You look back at the calm sea, at the place where the Titanic recently sailed.

00:25:52You climb aboard the rescue ship and promise yourself never to go on a sea voyage again.

00:26:01Is it possible to put out the sun?

00:26:04For example, what would happen if we poured all of the Earth's oceans on it?

00:26:08Or even more water?

00:26:10Well, let's find out!

00:26:13The universe is a place full of mysteries.

00:26:16Since ancient times, scientists have been arguing about how space works.

00:26:20But none of us has ever doubted the existence of one thing.

00:26:24The sun.

00:26:26Ah, the center of our solar system.

00:26:28It's big, bright, and... immortal?

00:26:31Nah, not really.

00:26:33The sun is just an ordinary star.

00:26:35It consists of 75% hydrogen, a little helium, and a pinch of other heavy elements.

00:26:42Gravity holds it all together.

00:26:45But in around 5 billion years, the life cycle of the sun will come to an end.

00:26:50The hydrogen inside it will run out.

00:26:52Our star will begin to grow gradually.

00:26:55And you can't even imagine just how big it will become.

00:26:59And then it will start eating all the nearby planets.

00:27:02That's when we'll regret being so close to it.

00:27:05After eating us all, the star will remain a red giant for another billion years or so.

00:27:10And then, sooner or later, it will begin to shrink and fade, turning into a white dwarf.

00:27:16In the end, nothing will remain of it but a bright and colorful planetary nebula.

00:27:22But don't get scared.

00:27:23Right now, the sun is in the middle of its life cycle.

00:27:26It was born about 4.5 billion years ago, and about the same amount of time remains.

00:27:31Fortunately, we were born during the star's best and most stable period.

00:27:35In other words, there's no reason to worry.

00:27:38So let's find one.

00:27:41How about speeding up the sun's life cycle with the help of water?

00:27:45We'll try to collect all the water on Earth and pour it onto the sun.

00:27:50First, we'll need a bucket.

00:27:52No, not this one.

00:27:53We'll need a really, really big bucket.

00:27:55The one that can contain around 326 million cubic miles of water.

00:28:01It will be equal in size to the distance from Washington to Chicago.

00:28:05Or, if we can only find ordinary buckets, there should be around 70 quintillion of them.

00:28:11This is a number with 18 zeros.

00:28:15Okay, imagine that we magically got that many buckets.

00:28:18It's time to put out the sun.

00:28:20We splash the star with all this water and...

00:28:23Nothing?

00:28:24Seriously?

00:28:25Oh, just look at this.

00:28:27The sun has probably felt sorry for us and produced one little solar flare.

00:28:32It turns out that all water on Earth is actually just a pathetic drop for the sun.

00:28:38People often underestimate how much bigger the sun really is than our planet.

00:28:42In reality, it can fit more than 1,003,000 Earths.

00:28:48So yes, the sun won't go out or even get colder.

00:28:51It won't even notice that we've done something.

00:28:53But let's not give up.

00:28:54We really want the sun to go out for some reason.

00:28:56What happens if we pour just enough water on it?

00:28:59And how much is this enough?

00:29:02Remember our quintillions of buckets?

00:29:04Well, we actually need about 370 octillions of them.

00:29:09This number has 27 zeros.

00:29:12It's hard to even imagine, so let's just say that it's a lot of water.

00:29:16Now, let's splash it all over the sun again.

00:29:19Wow, just look at the steam!

00:29:21But the sun hasn't gone out again.

00:29:23On the contrary, it said thank you and suddenly became much bigger and brighter.

00:29:28What's happening?

00:29:30You see, the sun isn't actually a campfire.

00:29:33Inside bonfires, candle flames, there's a chemical combustion.

00:29:37When we pour water on the fire, the water absorbs the heat of the flame

00:29:41and cools it to such an extent that it can no longer maintain the burning reaction.

00:29:45It also blocks the fire's access to oxygen.

00:29:48Water basically stops the chemical process.

00:29:51But the burning of the sun isn't the same reaction.

00:29:55Even though we say it burns, it's not entirely true.

00:29:58What happens there is called nuclear fusion.

00:30:01It's one of the most violent and craziest reactions in the universe.

00:30:06There are many layers of hydrogen going deep into the sun.

00:30:10If you take four hydrogen atoms and ram them together, you're left with an atom of helium.

00:30:16When we talk about the sun, the process is a little more complicated.

00:30:20When the star tries to carry out that fusion, positive protons repel each other.

00:30:25It takes a lot of force and energy to somehow squeeze them together.

00:30:31Fortunately, there's a magical force in space.

00:30:34It's gravity.

00:30:35The sun takes up 99.8% of all the mass of the solar system.

00:30:40Pretty heavy, right?

00:30:42And all this mass is what holds the sun together with the help of an incredible gravitational force.

00:30:48So, gravity takes quadrillions of these little hydrogen atoms and pushes them together every second of every day.

00:30:56And when they collide, they release some energy.

00:30:58So, unlike fire, the sun doesn't need oxygen to live.

00:31:03It needs hydrogen.

00:31:05And we all know that water is H2O.

00:31:08It consists of hydrogen and oxygen.

00:31:11So this is literally fuel for the sun.

00:31:15It's like trying to put out a fire with gasoline.

00:31:17More importantly, the extra mass added by water will make the sun heavier.

00:31:22Now, gravity says, thank you for your help.

00:31:25And then, it starts to collide protons with each other even faster.

00:31:29And thanks to this, the synthesis speeds up.

00:31:33Great, we've made the sun incredibly strong.

00:31:36And now it has eaten us, along with other nearby planets.

00:31:40And if we keep adding water, the sun will sooner or later collapse in on itself.

00:31:45It will blow off its outer layers and become a black hole.

00:31:49Awesome.

00:31:50Now it will pull inside absolutely everything around.

00:31:54Good job, guys.

00:31:56Let's press rewind because clearly our water experiment was a mistake.

00:32:00One small solar flare sounds much better.

00:32:03Alright, we're back to our usual calm sun.

00:32:06But it seems like there's something that we've forgotten.

00:32:11Well, apparently, water was critically important for life on Earth.

00:32:15Who would have thought?

00:32:16Now there's a huge amount of unmoving fish and other marine creatures lying around where the oceans used to be.

00:32:22Poor things.

00:32:24As for deep sea creatures, they simply didn't withstand such a sharp change in pressure.

00:32:30Algae and corals have also dried up.

00:32:32Wait a minute.

00:32:33Weren't they responsible for producing 50-80% of the world's oxygen?

00:32:37Oops.

00:32:38It's time to put on some oxygen masks.

00:32:41And how are things on dry land?

00:32:43I mean, now everything is just land.

00:32:46But you get the point.

00:32:47Wow, this whole place is lit.

00:32:49And I mean it literally.

00:32:51If there are no oceans, then there are no clouds or rain.

00:32:55Now there are forest fires everywhere.

00:32:57Poor animals have to escape and leave their homes.

00:33:00Oh my.

00:33:01And it's not like they'll be able to find a new home.

00:33:04Because all plants, of course, will dry up quickly.

00:33:07There will be literally no place for living left on the planet.

00:33:10So now Earth looks like a giant desert.

00:33:13Great!

00:33:14But people have been living in deserts for thousands of years, right?

00:33:17Maybe they'll know what to do.

00:33:19They won't.

00:33:20After all, people in the desert also need to drink.

00:33:23So now there's total chaos everywhere and survivors fight for the last drops of water.

00:33:29If there are any survivors at all.

00:33:31In fact, no matter how much they fight for resources, their fate is sealed.

00:33:37The ocean absorbs a huge amount of CO2 and the heat coming from the sun.

00:33:42They also distribute this heat throughout the planet, making it pleasant to live on.

00:33:46But once they're gone, the temperatures will quickly jump to 250 degrees Fahrenheit and above.

00:33:53But even if we forget about the high temperatures,

00:33:56now we have no clouds and they helped us too by not letting through solar radiation.

00:34:02So we're also under the direct impact of the sun's rays.

00:34:05Our last hope is icebergs.

00:34:07Now that everything is terribly hot, they've melted.

00:34:10And maybe they'll be the last hope for humanity.

00:34:13But that cool solar flare was definitely worth it.

00:34:17Silly humans.

00:34:20We're so used to the things our body does to keep us alive each day

00:34:24that we barely ever think about the mechanisms of sleeping, talking, breathing, or even blinking.

00:34:30But what would happen to your body if you stopped doing each of these things all of a sudden?

00:34:35How long would it be before it became a problem?

00:34:39Not that I have ever considered taking some sort of vow of silence.

00:34:43But I do sometimes wonder what would happen if I just stopped talking altogether.

00:34:48Would I lose my voice forever at one point?

00:34:51Let's look at what specialists at Columbia University have to say.

00:34:55First of all, our vocal cords are muscles.

00:34:58So they do need a workout every now and then to stay in shape.

00:35:02If you stopped speaking, these muscles would start to get weaker after a while.

00:35:06As a result, your voice would become quieter and its pitch would get higher.

00:35:11Even worse, this might make it sound hollow.

00:35:14And basically, it would be harder for you to speak overall.

00:35:18In a way, it's one of those situations where if you don't use it, you lose it.

00:35:23Well, kind of.

00:35:26Luckily, breathing and eating would enter into the equation here.

00:35:30These processes would keep your muscles in some shape.

00:35:34Plus, no matter how long you kept silent, it wouldn't do any permanent damage.

00:35:39And once you started using your vocal cords again, your voice would be back.

00:35:45We all know what might happen if we stopped washing.

00:35:48We'd smell.

00:35:50But let's look at it from a scientific point of view.

00:35:53How about an experiment where a person stops showering for a whole year?

00:35:59Depending on its type, a person's skin would initially become either extremely oily or very dry.

00:36:06The oiliest parts of their body, like behind the ears and the neck, would collect dust and pollutants and even change color.

00:36:14As for their head, it would get very itchy because of all that skin buildup.

00:36:19And after such a long time of not having a proper cleaning routine, it could take weeks to get the skin back to normal.

00:36:28It may sound like a vacation of sorts, but let's look at what would happen if you never got out of bed.

00:36:35One of the first organs to feel the change would be our lungs.

00:36:39Without gravity to pull them down into their standard position, their lower part would crease.

00:36:44But coughing every now and then would help to reduce this effect.

00:36:49Going further, you'd start to lose about 1% of your bone density with each passing week.

00:36:55This would make your bones more fragile.

00:36:58By the way, it's also the reason why astronauts, who can go for months without experiencing gravity,

00:37:03need to move around for at least 2 hours a day and make sure they have enough calcium in their diet.

00:37:10That same 1% would also apply to your muscle mass.

00:37:14You'd first start to see the effects of this lack of movement in your thighs and shoulders.

00:37:20The unused sugars that previously went to the muscles would start to build up in the blood system after about 10 days.

00:37:27After a whole month in bed, your heart would end up pumping 30% less blood with each beat.

00:37:33There would be less oxygen in your body, and you'd feel even more tired, which sounds kind of surprising.

00:37:40After all, you'd spend the entire month in bed.

00:37:45What would happen if you held your breath for too long?

00:37:48Let's have a look at the timeline.

00:37:51Firstly, the oxygen levels in your brain would decrease, followed by a higher level of carbon dioxide.

00:37:58Usually, your body gets rid of this gas pretty fast when you breathe out.

00:38:04After about 60 seconds, the cells in your body would start to behave differently than they normally do.

00:38:10All body parts would be affected by the sudden change.

00:38:13Your heart would start to beat irregularly.

00:38:16If you didn't begin to breathe even at this point, you'd most likely end up fainting.

00:38:21Similar to so many other mammals, we humans have a diving response.

00:38:26This is a built-in automated mechanism that you come equipped with.

00:38:30It makes sure that your brain always has enough oxygen, even in an emergency situation.

00:38:36This diving response starts working extra hard every time your face ends up in the water.

00:38:42But it can happen on dry land as well.

00:38:46Its main aim is to make sure your brain continues functioning, no matter the cost.

00:38:51So, it orders your body to redirect all the blood from non-essential body parts, like legs or arms, to the brain.

00:39:01Now, what would happen if you stopped blinking?

00:39:04Or if you didn't blink frequently enough?

00:39:07Firstly, your corneas would likely increase in size.

00:39:10The cornea is the only part of your body that doesn't have a blood supply.

00:39:14But it still needs oxygen to function properly.

00:39:17And it gets it straight from the air.

00:39:21By the way, that's the reason why your cornea swells up, just a bit, when you sleep.

00:39:27But it goes back to normal in the morning.

00:39:31Then, your eyes would probably start to open.

00:39:35Then, your eyes would probably start to dry out, because the tear film wouldn't get restored.

00:39:41What does this mean? Mostly some pain and blurry vision.

00:39:47Blinking also helps with removing all dirt and dust from your eyes.

00:39:51And if you stopped moving your eyelids, things would most likely get stuck in your eyes and cause serious damage.

00:39:59We take chewing for granted, don't you think so?

00:40:02But come to think of it, it's the first stage of digestion.

00:40:05Chewing helps your stomach to process the food you eat more easily, by breaking it into smaller parts.

00:40:13Chewing less, or not at all, should you ever resort to a full liquid diet,

00:40:18might cause harm not only to your digestive system, but, surprisingly, to your jaw muscles as well.

00:40:25Without regular chewing movements, your facial features would change pretty soon.

00:40:32Chewing also lets your stomach know when it's time to increase its acidity, so it can process food better.

00:40:40Your senses are a huge part of your day-to-day lives.

00:40:43And here's a neat trick that the human brain can do.

00:40:46When one sense is lost or damaged, another can become much more heightened.

00:40:52People with bad eyesight may be able to hear better,

00:40:55while those who have problems with their hearing might have some sort of enhanced vision.

00:41:01Recent research has shown that the brain can actually remodel itself,

00:41:05giving more power to other senses when one is damaged or missing.

00:41:11They notice this in microscopic roundworms.

00:41:14They have a peculiar behavior when they have a poor sense of touch.

00:41:18Then, their sense of smell becomes super sensitive,

00:41:22and they manage to seek out food sources with a very faint scent.

00:41:27Similarly, some visually impaired people have something in common with bats.

00:41:32Such people basically learn to use their boosted hearing to navigate the world more efficiently.

00:41:38They make a series of rapid clicking noises.

00:41:41This is just how bats use their built-in sonar to find their way when there's no light.

00:41:48Your brain is home to 86 billion neurons.

00:41:52It shouldn't come as a surprise that it also has some sort of a backup plan

00:41:56when some of its parts fail, right?

00:42:00But then there's another question.

00:42:02Why aren't our senses heightened from the very beginning?

00:42:05I mean, we're obviously born with this capability,

00:42:08so why don't we just activate it by default?

00:42:12The explanation is a bit complex.

00:42:15Mostly, it all comes down to your body's inability to work really hard for extended periods of time.

00:42:21To be more precise, your body is always looking to obtain, and maintain,

00:42:26a certain balance in order to function properly.

00:42:31When one sense is deprived, another needs to be sharper.

00:42:34More so, all these changes in our senses, depending on the circumstances, appear to be reversible.

00:42:41This yet again illustrates the human body's need to function in harmony.

00:42:47It's one of the most intriguing locations in the world.

00:42:51Covered in darkness and miles underwater,

00:42:54this extreme environment is home to some unusual creatures and phenomena.

00:42:59It's called the Mariana Trench, and it's the deepest oceanic trench on Earth.

00:43:04No wonder it's been so difficult to explore.

00:43:07Because of the risky conditions, people aren't able to explore this location without proper equipment.

00:43:12But what would happen if we threw a steel ball down there?

00:43:17Let's start with some basics.

00:43:19How did they first discover this enormously deep hole in the ocean?

00:43:23HMS Challenger identified it back in 1875.

00:43:27The ship had some pretty fancy-sounding equipment for its time,

00:43:30but it wasn't nearly good enough to be able to fully explore the trench.

00:43:34Some decades later, in 1951, another ship, the HMS Challenger II, came back to the location better equipped.

00:43:42The vessel featured an echo sounder,

00:43:44and was able to take accurate measurements of what seemed to be the deepest point on the surface of our planet.

00:43:50If you were to look at it in 2D,

00:43:52you'd see the trench measures 1,500 miles in length and 43 miles in width on average.

00:43:58It also looks sort of like a crescent-shaped scar when you observe it from above.

00:44:03Nothing out of the ordinary so far, right?

00:44:06Well, if you were to stretch a wire from the surface of the ocean to the trench's deepest point,

00:44:11it would measure a staggering 7 miles.

00:44:14If we were able to physically move Mount Everest,

00:44:17which is the Earth's tallest mountain,

00:44:19to cover the Mariana Trench,

00:44:21it still wouldn't be enough, falling short by about a mile.

00:44:26Because the Mariana Trench is so deep,

00:44:28it's almost completely covered in darkness,

00:44:31as light can barely get through to such extreme distances underwater.

00:44:35The temperature isn't any friendlier either,

00:44:38just a few degrees above freezing.

00:44:40But the most dangerous feature of them all is the water pressure.

00:44:44Right at the deepest point of the trench,

00:44:46the amount of pressure is about a thousand times higher than the standard atmospheric pressure.

00:44:53Not a lot of people ever attempted to descend into the Mariana Trench.

00:44:57In fact, the first organized attempt took place more than 60 years ago.

00:45:02It was done by Jacques Piccard and Don Walsh in a submersible.

00:45:07They only spent about 5 hours on their descent,

00:45:10and a mere 20 minutes at the bottom.

00:45:12Alas, they weren't able to take any pictures.

00:45:15Until these two scientists were able to descend,

00:45:18specialists believed there was little to no chance that life could exist down there,

00:45:22given the conditions, most notably the extreme pressure.

00:45:26But while at the bottom, the submersible's floodlight caught sight of a creature.

00:45:31It was a very flat one indeed.

00:45:35As you can imagine, resources here are very scarce.

00:45:38What kind of creatures live down here?

00:45:40And how do they survive, given the harsh environment?

00:45:43Surprisingly, there is quite an abundance of wildlife living in the Mariana Trench.

00:45:48Some of these creatures fall back on chemicals to survive,

00:45:52like methane or sulfur,

00:45:54while other kinds of fish nibble at the marine life that's,

00:45:57well, weaker than them on the food chain.

00:46:00The most common creatures found here are xenophyophores,

00:46:03amphipods,

00:46:05and small sea cucumbers.

00:46:08Some of them adapted by hardening up their shell,

00:46:11using aluminum harnessed from the seawater.

00:46:14Smaller creatures, like microbes, adapted by feeding on the chemicals emitted

00:46:18when the seawater hits the underwater rocks.

00:46:21They consider the Mariana snailfish the rock star of the area in terms of wildlife.

00:46:26They're small, ranging from 3 to 9 inches,

00:46:29translucent, and lacking any scales.

00:46:32But they're the top beast of prey in the area.

00:46:36It's no wonder some people started to believe that the ancient megalodon might still be living here.

00:46:41What was a megalodon, you might be wondering?

00:46:44It was the largest predator ever known in our planet's history.

00:46:47Basically, the biggest and nastiest shark ever to have lived.

00:46:51Scientists believe it's been extinct for quite some time,

00:46:54and the idea that it might still be hiding in the Mariana Trench

00:46:57doesn't have a lot of supporting information.

00:47:00The megalodon would have needed to learn to navigate in complete darkness.

00:47:04It would either have to be bioluminescent, or evolve to have massive eyes.

00:47:08More so, because of its school bus-like size,

00:47:11the megalodon would have needed a lot to eat.

00:47:14Microbes and small snailfish just wouldn't have done the trick.

00:47:19If a steel ball were to be dropped in the trench, what would be its effect on it?

00:47:23Would the ball be strong enough to sustain such pressure?

00:47:26Let's look at the science here.

00:47:29If we assume it's a solid steel ball,

00:47:31the pressure found at the bottom of the trench wouldn't be enough to really affect it,

00:47:35and cause permanent damage.

00:47:37It would take it a solid 12 minutes to reach the bottom of the ocean, though.

00:47:42What about the temperature?

00:47:44Well, it turns out that the difference in temperature on the surface,

00:47:47and at the bottom of the trench, is quite impressive.

00:47:50A difference of about 86 degrees Fahrenheit.

00:47:54So, it would cause the ball to shrink a bit.

00:47:57But, yet again, once the ball returns to the surface,

00:48:00it would simply come back to normal.

00:48:03Should the ball get stuck there?

00:48:05There's another interesting question to answer.

00:48:07Would corrosion affect it?

00:48:09Corrosion of steel is highly dependent on the amount of oxygen in the water.

00:48:13The amount of oxygen dissolved in water remains constant at depths greater than 3 miles.

00:48:18I'll spare you the math,

00:48:20but it would take more than 10,000 years for the steel ball to completely rust under the sea.

00:48:27I can't help but wonder, though,

00:48:29what would it take us humans to be able to survive at such extreme depths?

00:48:33Let's look at what was used in the past to explore this mysterious location.

00:48:37A little thing called syntactic foam.

00:48:39Why?

00:48:40Because it's the only material that can both float and resist the amount of pressure found here.

00:48:45Without this sort of protection, our lungs would rapidly collapse here.

00:48:49More so, the pressure from the water would push liquid into our mouths,

00:48:53replacing the much-needed oxygen with water.

00:48:58Then, there would be the much-needed ability to be able to come back to the surface,

00:49:02should anything not go as planned.

00:49:04One of the vessels that went for a deep dive here

00:49:07had 1,000-pound steel weights attached to it,

00:49:10so it would ensure its sinkage.

00:49:12These weights were connected to the ship by a special type of wire

00:49:16that had an increased corroding time of 11 to 13 hours in seawater,

00:49:20just in case something went wrong down there,

00:49:22and they'd have to bounce back faster.

00:49:25Given the harsh conditions here,

00:49:27the problem of oxygen supply is really important, too.

00:49:30Any vessel looking to descend into the Mariana Trench again

00:49:33would need to consider some sort of device that can recycle the air

00:49:37in order to reduce the amount of oxygen that needs to be transported down there.

00:49:42And the last, but definitely not the least of all problems, would be electricity.

00:49:47There surely isn't a power socket down there for you to charge your phone.

00:49:51So, there needs to be enough battery life to support all the necessary equipment.

00:49:55None of these problems seem to be quite the challenge anymore,

00:49:58since, as of recently, you can buy a tour of the Mariana Trench.

00:50:02Three lucky individuals were part of such a project back in 2020.

00:50:07They were submerged in a 3.5-inch-thick titanium sphere.

00:50:11This ensured that they didn't feel any pressure changes,

00:50:14and that they didn't have to worry about their health.

00:50:18The Mariana Trench is the largest in the world,

00:50:22This ensured that they didn't feel any pressure changes,

00:50:25and physiological stresses whatsoever.

00:50:27Each of the guests took part in an individual trip

00:50:30that had an estimated length of about 14 hours.

00:50:33The descent itself took over four hours.

00:50:36Once they reached the bottom,

00:50:38they got the chance to witness some of the most extraordinary creatures on the planet.

00:50:42Then it was time to start the four-hour ascent back to the surface.

00:50:46Night.

00:50:47You and your friends are riding bikes around a small city,

00:50:50and notice a meteorite flying in the sky.

00:50:52It burns with a bright green flame and then falls right into a small pond near the town.

00:50:57You instantly dash to the crash site.

00:50:59The water on the pond's surface is foaming and bubbling.

00:51:02The incandescent meteorite slowly sinks to the bottom

00:51:05and illuminates the black waters with a green light.

00:51:08Mesmerized by this picture, you approach the edge of the pier.

00:51:11The green glow is reflected in your glasses, beckoning you.

00:51:15You take a step.

00:51:16Suddenly, you fall into the water and pass out.

00:51:20You wake up in the hospital.

00:51:22You grab the edge of the bed to get up and feel how it crunches under your fingers.

00:51:26You look at your palms and scream.

00:51:28They are all covered with steel.

00:51:30Your friends come and tell you that you flew out to the shore,

00:51:33probably after you've touched the meteorite.

00:51:35Then, inside your body, some changes at the genetic level began.

00:51:40They put a mirror in front of you.

00:51:42You take a glance and see yourself, covered with steel.

00:51:46You don't feel fear, but you're screaming in delight instead.

00:51:50You're made of metal now.

00:51:52Not exactly, your friend explains.

00:51:55Your skin cells are covered with a layer of the thinnest and strongest steel,

00:51:59and everything else in your body is ordinary as it has always been.

00:52:02Your movements are not constrained.

00:52:04It's like you're covered in a knight's chainmail made of nanosteel particles.

00:52:09You look out the window and take a deep breath.

00:52:11Your lungs are filling up with air.

00:52:13But what about the skin?

00:52:15The doctor comes in and says that your skin cells no longer need oxygen.

00:52:19There are no pores the air used to penetrate through any longer.

00:52:23Your lungs have become more voluminous to make up for the lack of oxygen.

00:52:27Also, you can hold your breath for a longer time.

00:52:30At night, you can't sleep because the steel eyelids put a lot of pressure on your eyes.

00:52:35You decide to leave the room, but the door is closed.

00:52:38You push the handle harder and the lock breaks.

00:52:41You step out and meet the doctor.

00:52:43He asks you to come back since your treatment is not finished,

00:52:46and tomorrow you will be transferred to another place.

00:52:49You say you feel great and you want to leave.

00:52:52The doctor tries to grab you and you run away.

00:52:54The siren turns on.

00:52:56You understand that they want to transport you to a secret lab for research and experiments.

00:53:01Several orderlies surround you.

00:53:03You clench your fists and hit the wall.

00:53:06It collapses easily, as if it was made of cardboard.

00:53:09You break through the walls and leave the hospital.

00:53:12You tell your friends about what happened, and all of you decide to leave the town for a while.

00:53:16You get on your bikes, and at this moment, several black cars appear on the road.

00:53:21They come for you.

00:53:23You ride away from them and go into the forest, where cars can't pass.

00:53:26Several scientists in men in black suits are chasing you.

00:53:30You come to the pond and remember the doctor's words about enlarged lungs.

00:53:33You decide to hide under the water.

00:53:35You jump and slowly fall to the bottom.

00:53:38Ten minutes have passed, and your lungs still have a small supply of air.

00:53:42The pursuers can't find you and leave.

00:53:44You try to swim out but drown.

00:53:46The steel skin has made you heavier and unable to swim.

00:53:49You push off from the bottom but drown back.

00:53:52Fortunately, your friends jump into the pond and help you get out.

00:53:56You're wet, but the skin doesn't rust, and it dries quickly.

00:54:00You ride a bicycle towards a cheap hotel to hide there and figure out what to do next.

00:54:05The sun shines brightly.

00:54:07You spend several hours pedaling.

00:54:09Your friends are sweating, but you aren't.

00:54:11The skin is covered with dust now, but it's enough to wipe it with a rag to look clean again.

00:54:16In a normal body, sweat is released to cool the body and prevent it from overheating.

00:54:20Your body doesn't cool down now, but that's okay.

00:54:23Your skin becomes so hot that you can fry an egg in your palm.

00:54:27Fire and cold temperatures aren't harmful to you either.

00:54:30You check into a motel and realize that it's hard for you to move.

00:54:34You hear the grinding of metal when you raise your hands or walk.

00:54:37Your friend gives you the oil that lubricates the chain on the bike.

00:54:41You cover the skin with it, and it works!

00:54:43You're moving freely again.

00:54:45Steel skin increases your weight and the load on all your muscles.

00:54:49You quickly get used to it, and your body becomes more trained in a few hours.

00:54:53But the coolest thing is a superpower.

00:54:56Not only can you destroy a wall or tear an iron plate, but also break glass with a light torch.

00:55:02At the motel, you go to the refrigerator and grab some magnets.

00:55:06They stick to you, and it's pretty tricky to remove them.

00:55:09You turn on the TV, and they tell you that you and your friends are wanted.

00:55:12You're all on channels!

00:55:14You all leave the motel and get on your bikes and drive as far away as possible.

00:55:18You turn the pedals so hard that they break.

00:55:20To continue your trip, you decide to rent a car.

00:55:23After a couple of hours, you run out of gas.

00:55:25Your weight has increased, which means the vehicle consumes more fuel.

00:55:30You and your friends are walking along the road.

00:55:32An old pickup truck stops.

00:55:34A driver with a thick beard offers to take you to the nearest town with a railway station.

00:55:39The driver keeps silent all the way.

00:55:41The beads of sweat are running down his face.

00:55:44Is he nervous?

00:55:45You feel that something is wrong.

00:55:47When you enter the town, you see your photo on every streetlight.

00:55:51There's even a reward announced for your capture!

00:55:53You ask the driver to stop, but he doesn't listen to you.

00:55:56Then you punch through the car floor with your feet and crash into the asphalt.

00:56:00The car stops.

00:56:02There's not even a scratch on your legs.

00:56:04Several black vehicles drive up to you from different streets.

00:56:07The car doors flung open abruptly.

00:56:09People in black suits caught your friends, but you managed to escape.

00:56:13You run to the roof of a five-story house.

00:56:16Scientists and men in black surround you.

00:56:18You go to the edge and jump.

00:56:21Like a real superhero, you land on half-bent legs.

00:56:24The asphalt under you is destroyed, and your sneakers are torn.

00:56:28You run away, touch the parked cars with your hand and leave big scratches on them.

00:56:32You run into the forest and decide to spend the night here.

00:56:35You break several thick branches with the palm of your hand and make a fire.

00:56:39You don't need it since you can't get cold, but you just don't want to stay in complete darkness.

00:56:44You hold your hand over the fire and feel nothing.

00:56:46You look at the tip of your fingers and realize that there are no fingerprints on them.

00:56:50You close your eyes and imagine your future life.

00:56:54All metal detectors go crazy when you pass through them.

00:56:57Banks, the airport, nightclubs.

00:56:59You make the security service nervous everywhere.

00:57:02But the worst thing is that you will be hiding almost all your life.

00:57:05You fall asleep and see laughing people pointing at you.

00:57:09You don't like it, and you wake up.

00:57:11After a few seconds, you suddenly understand what you need to do next and how to stop the pursuit.

00:57:17You wander through the forest for several hours.

00:57:19Your skin creaks because of the lack of lubrication.

00:57:22Finally, you go out on the road, then see a roadside hotel with cars parked nearby.

00:57:27You open the trunk of one of them and pick up a bottle of engine oil.

00:57:31Then you quietly enter the hotel, get into a room and charge the phone.

00:57:35An hour later, a woman comes in.

00:57:37She screams when she sees you.

00:57:39You grab your phone and jump out the window.

00:57:41Several black cars pull up to the hotel.

00:57:44A helicopter appears in the sky.

00:57:46You run to a dump with abandoned cars and turn on the camera on your phone.

00:57:50You record yourself and tell your story.

00:57:52You admit that you didn't choose this superpower and want to live a normal life.

00:57:57Afterward, you post it on all social medias.

00:58:01Suddenly, somebody turns on the power crane, which drags the old cars with a giant magnet.

00:58:06You stick to the magnet and can't move.

00:58:09When people in black caught you, there's nowhere to run.

00:58:13But right at this moment, reporters and ordinary people are coming to the dump.

00:58:18Now, when everyone knows your story, you are protected from experiments in the lab.

00:58:36The Power of Imagination

00:58:47Imagine you wake up one day to a world with no electricity, no internet, no money, no work or school.

00:58:56Nothing that you're used to.

00:58:58No, you're not in California when they shut the power off.

00:59:01You're not even in your own home.

00:59:03Because you've been magically transported to the Stone Age.

00:59:07What could possibly happen next?

00:59:09Of course, your first reaction would be shock.

00:59:12But let's move past that.

00:59:14You've now accepted that you get to experience life Flintstones style.

00:59:18First, let's look around.

00:59:21This is your cave, where you live with your family.

00:59:24You have your own sleeping area that's covered in animal skin.

00:59:27However, you might also live in a primitive hut supported by mammoth tusks and ribs.

00:59:32With an animal skin over it as protection from the rain.

00:59:35Your morning routine won't include a quick trip to the bathroom or to brush your teeth or a hot cup of coffee.

00:59:41And if you're wondering where the Stone Age people did their business, well, it was basically anywhere outdoors.

00:59:47How convenient, just pick a bush and go.

00:59:51All right, it's time to get out and explore the New World world.

00:59:55But hey, don't forget to put on your clothes.

00:59:58No, nothing comfy and trendy from the mall.

01:00:01Back in the day, humans used the skins of the animals they hunted to create simple, rough loincloths.

01:00:07To make these hides more flexible, they had to chew them.

01:00:11Let's assume you already have an outfit for today and don't have to strain your jaws right now.

01:00:16Thousands of years in the future, humans will learn how to smoke these animal hides to make them last longer and start making tunics.

01:00:24What about footwear?

01:00:26Scientists believe it was present around 40,000 years ago.

01:00:29Take a small piece of animal skin and wrap it around your foot.

01:00:33Then stuff hay under the heel to create some kind of sole.

01:00:37Voila, one shoe is done.

01:00:39Do the same with the other foot and you're ready to roam.

01:00:43Now, don't be scared.

01:00:45You're not going to face a giant mammoth right outside the shelter.

01:00:49Ancient humans were pretty smart and learned animals' habits because it was the only way to survive in the wild.

01:00:55So, they chose caves or built huts in the safest places they could find.

01:01:00Now, go down to the river and wash your face.

01:01:03Are you curious to find out what you'd look like in the Stone Age?

01:01:07Take a peek at your reflection in the water.

01:01:09See, you're not that much different from the modern you.

01:01:13Just that your hair is a mess and you might be a few inches shorter, with a more developed jaw because of the harsh diet.

01:01:20And look at those bulky muscles.

01:01:23Well, that's what you get when your life is all about running and fighting with wild animals while hunting.

01:01:28Yes, hunting is on your to-do list today.

01:01:31But first, it's time for breakfast.

01:01:33Luckily, you have some leftovers from dinner.

01:01:36Eggs, wild fruits, and berries.

01:01:39Sorry, no gas stove to cook the eggs.

01:01:41Why not try to do it over the fire?

01:01:43Here's a free tip.

01:01:45Find two small but sturdy and dry wooden sticks.

01:01:48Place some dry leaves or a chunk of your own hair at the base for kindling and rub the sticks vigorously against each other.

01:01:54Keep going, be patient.

01:01:57Okay, finally there's an ember.

01:01:59Good job.

01:02:00Now you can cook your breakfast using a flat stone as a frying pan.

01:02:04Need a fork?

01:02:05Sorry, that won't be invented for thousands of years.

01:02:08See that seashell attached to a wooden stick?

01:02:10That is your spoon.

01:02:12Come on, the jungle is waiting for you.

01:02:15Thankfully, the Ice Age is long gone, so the weather is warm and lush greenery is in abundance.

01:02:20That's good for you since you have to pick different edible plants, nuts, fruits, and wild grains.

01:02:26It wasn't until around 10,000 BCE that folks in the Stone Age learned how to grow their crops and domesticate animals.

01:02:33Only then could they finally stop moving from place to place in search of good hunting grounds.

01:02:38Oh look, there's some grapes. Let's snatch them.

01:02:42But how do we gather grains, you might be wondering?

01:02:45Well, allow me to introduce you to some Stone Age tools.

01:02:49By the way, the Stone Age is named after the tools that humans invented that were made out of...

01:02:55wood?

01:02:56No, obviously stone.

01:02:58Let me help you out again.

01:03:00Here's a U-shaped stone sickle that knocks down the grain stalks.

01:03:04It's time to bring everything you've collected to your camp.

01:03:08Now that the shock of time traveling has worn off, you notice that there are a few other huts near your dwelling.

01:03:14Those are your neighbor.

01:03:16Betty and Barney Rubble, I guess.

01:03:18Stone Age people usually united in groups of 20 to 50 and helped each other to survive.

01:03:23Okay, you can eat grapes and other fruits raw, but what can you do with raw grain?

01:03:29To separate the grains from the husks, take a stone bowl and a small grinding stone and grind the grains.

01:03:35Now, if you mix smashed grains with water, you'll get gruel.

01:03:39Fry it on stones the way you did with the eggs, and there's your first flatbread.

01:03:44Yeah, it doesn't taste amazing, but don't forget, it's going to be another 15,000 years before your favorite bakery gets built.

01:03:51Is it dusk already?

01:03:53Brace yourself, my friend, because you are about to go hunting.

01:03:57But I've got good news for you.

01:03:59You don't have to do it alone.

01:04:01Stone Age people survived this period because they did almost everything together.

01:04:05So, call up your camp neighbors and get ready.

01:04:09How would you feel living in such harsh conditions?

01:04:12Let me know in the comments.

01:04:14But how did humans communicate back then?

01:04:17At the very beginning of the Stone Age, they only used a series of cries and gestures to express their fear, joy, pain, or warning to the others about imminent danger.

01:04:27It was much later that they learned how to pronounce specific sounds using their teeth, tongue, and mouth.

01:04:34That's how both speech and language was developed, which made their life much easier and leveled up their teamwork.

01:04:41Of course, anthropologists have no clue how exactly their language sounded since obviously no written traces are left, and nobody left any tapes either.

01:04:50Oh, what's a tape?

01:04:52Ancient technology. Don't worry about it.

01:04:55So, you and your camp fellows need to take some special hunting tools with you.

01:05:00What are they?

01:05:01The first and most primitive things used for taking animals down were long, sharpened wooden sticks, and sometimes just a big rock.

01:05:08But over time, sharpened sticks turned into sophisticated spears.

01:05:13The points weren't made of metal yet, of course. It's too early for that.

01:05:16Instead, they used small, sharp-edged stones attached to a long bone or stick.

01:05:22This was a very important invention since it made hunting less dangerous.

01:05:26Their chances of staying alive were better because they didn't have to get as close to an animal and could hunt it from a distance.

01:05:33As dusk settles, your hunting group goes deep into the jungle.

01:05:38You should be looking for large herbivore animals like elephants, woolly mammoths, giant bison, deer, and reindeer.

01:05:45They won't be only your dinner, but will also give you a supply of furs, bones, horns, and hides that you can use for your household.

01:05:54There were two main hunting techniques back then.

01:05:57The first was rather time-consuming but safe.

01:06:01It included digging a huge hole around the place where animals went to drink water.

01:06:05That hole served as the trap for your game.

01:06:08But you're going to have to dig it out without a spade or shovel.

01:06:11You'll need the help of a digging stick.

01:06:14A wooden stick with a horn at the top.

01:06:16Or a large cleaver, an oblong-shaped stone or bone.

01:06:21After the hole is ready, you'd have to hide nearby and wait patiently for an animal to fall in.

01:06:27The other technique required the whole hunting party chasing the animal down and forcing it into mud and water channels where they'd get stuck and have no way to get out.

01:06:36Did you see that? It's a deer!

01:06:38Run! Run as fast as you can!

01:06:40And try to corner it straight into the swamp.

01:06:43Oh no! It got away.

01:06:45Yeah, not every hunting session is going to be a success.

01:06:49In fact, most won't.

01:06:51But your tribe still needs something for dinner.

01:06:54Better move on to fishing then.

01:06:56Don't worry, you won't have to catch fish with your bare hands.

01:07:00Fishing nets and harpoons are at your disposal.

01:07:03Nets were made from tree bark and grass.

01:07:06The oldest one, found by archaeologists, dates back to 8300 BCE.

01:07:12Harpoons made of antlers usually had a rope to pull the catch back up to shore.

01:07:17It was used mostly for big targets like whales, tuna, and swordfish.

01:07:22Okay, once you've asked around where a good spot would be, throw the net in the river.

01:07:27Now you have to wait.

01:07:29Oh look, there's some fish!

01:07:31Pull the net with all your might.

01:07:33Come on tribe, help him out.

01:07:35I mean, don't look at me, I'm just narrating here.

01:07:39Alright, good catch, and not a moment too soon.

01:07:42You've just made sure you won't go hungry tonight.

01:07:45Bring what you caught into the camp and get some rest.

01:07:48The others will take care of the catch.

01:07:50Now I know what you're thinking.

01:07:52It's all work and no play.

01:07:54And yeah, life in the Stone Age was anything but easy.

01:07:58But still, humans did have some forms of entertainment.

01:08:02No, you're not going to an amusement park or a cinema.

01:08:06But you can pass the time playing music on flutes made from bird bones and mammoth ivory.

01:08:12You can also take up a hobby like crafting, making necklaces and bracelets from tusks, bones, and shells.

01:08:19Or you can get full-on artsy and draw patterns on your body using a paint made from okra.

01:08:25It's a type of red clay.

01:08:27Or paint some pictures in a cave.

01:08:29Carve something crazy to make archaeologists in the future wonder what it meant.

01:08:34Can you smell that?

01:08:35It's dinner time.

01:08:37Go on, enjoy. You deserved it.

01:08:40Doesn't it taste so much better since you worked so hard for it?

01:08:44Alright, now that you've experienced a day in the Stone Age, let's take you back home to the modern day.

01:08:50The next time you complain that your internet is too slow or the food you ordered is 15 minutes late,

01:08:55think about how much harder life used to be for people in the Stone Age.

01:08:59And how it is only thanks to their tireless efforts to survive that you and I get to enjoy our pretty comfortable lifestyle today.

01:09:08Ladies and gentlemen, welcome to the fight of the century.

01:09:12In the left corner is the most famous dinosaur of all time, Tyrannosaurus Rex.

01:09:18Let's call her Ty-re-a-na.

01:09:21She existed about 70 million years ago and was a true queen in today's North American territory.

01:09:27No one could defeat her in a fair battle.

01:09:30Well, except for that big meteor.

01:09:32Spoiler!

01:09:33In the right corner is the nightmare of the sea, Megalodon.

01:09:38This one's named Megan.

01:09:40This species went extinct about 3 million years ago, but legends about it are still alive.

01:09:46It's the biggest shark that ever existed, and it was a super predator in its time.

01:09:52Both fighters are the highest predators in their category.

01:09:55But what happens when they meet face to face?

01:09:58To find out, let's move on to the first category, size.

01:10:03The largest T-Rex ever found was named Scotty.

01:10:06Hey, beam me up!

01:10:08His hips were about 12 feet tall.

01:10:10But if Scotty straightened his back, he would be about 42 feet tall.

01:10:15It's like putting three giraffes on top of each other.

01:10:18And if you wanted to pet this cute guy on the nose, you'd have to stand on the shoulders of seven people to reach him.

01:10:24Even though our T-Rex is not the biggest of its kind, Tyreana still remains one of the most dangerous.

01:10:31But now let's look at the size of her opponent.

01:10:34The size of the Megalodon is still a controversial thing.

01:10:38The fact is that the only remains of this ancient shark are teeth and vertebrae.

01:10:43So scientists can only guess about the real size of this shark.

01:10:47But even by the most modest calculations, it's bigger than T-Rex.

01:10:52Megalodon was about 50 feet long, which is more than a school bus.

01:10:57It was not only the most massive shark that ever existed, but also the largest fish in the world.

01:11:03Its closest competitor in size was a modern whale shark.

01:11:07But he loses to Megalodon by as much as 10 feet.

01:11:11So in the size category, Megalodon left no chance for T-Rex.

01:11:16The first point goes to the giant shark Megan.

01:11:20The next class is weight.

01:11:22Let's start with Megan.

01:11:24Usually adults had a weight of 27 to 59 tons.

01:11:28This is like three heavy-lift transport helicopters.

01:11:31Or almost like a tank.

01:11:33Actually, some houses have less weight than Megalodon.

01:11:36Its only competitor in the sea is the blue whale.

01:11:39What does T-Rex answer to this?

01:11:42Although it's an incredibly large predator, the largest individual rexes could only reach a weight of 14 tons.

01:11:49That's relatively small for its size.

01:11:52T-Rex could be terribly slow and clumsy, but some of its bones are hollow.

01:11:57This is what reduces its total weight.

01:11:59Thanks to this, she could be much faster and more agile without losing strength.

01:12:04But we see that Tyreana loses to Megan in weight by at least three times.

01:12:10So another point goes to Megalodon.

01:12:14Next up is speed and agility.

01:12:16According to different estimates, Tyrannosaurus rex could run at speeds of 11 to 45 miles per hour.

01:12:23For comparison, the speed of the fastest human on Earth is only 16 miles per hour.

01:12:29So you do the math.

01:12:31Yep, we wouldn't have had a chance to escape having lunch with, sorry, being lunch for T-Rex.

01:12:37But what about maneuverability?

01:12:39Tyreana seems to be big and clumsy.

01:12:43However, T-Rex had excellent balance because of her massive tail and could turn and change direction very quickly.

01:12:49And look at her legs.

01:12:51She clearly doesn't miss a leg day.

01:12:54Now let's look at the second fighter, Megan.

01:12:57Scientists have found that the Megalodon could swim at a speed of about 11 miles per hour.

01:13:02This was enough to become an ultimate predator, but it was inferior to many other species.

01:13:07For example, the fastest sea creature is the sailfish.

01:13:11It can reach 68 miles per hour, about 100 feet per second.

01:13:15Besides, because of its heavy weight, it could not quickly turn or maneuver.

01:13:20Imagine a giant truck needing to make a U-turn.

01:13:23So when she attacked, she had only one chance to strike.

01:13:27If she missed, she went for a second lap.

01:13:30This gave her prey enough time to run away.

01:13:33In this round, T-Rex finally gets her first score.

01:13:37But we're still 2 to 1 in favor of Megan the Megalodon.

01:13:41Okay, moving on to the next category, fighting skills.

01:13:45Megalodon was definitely the best predator in the aquatic world.

01:13:49Not only because of its size and mass, but also because of its intelligence.

01:13:54Scientists have found traces of Megalodon's teeth on the remains of whales.

01:13:58They concluded that Megan aimed at her prey's weakest spots and knew where the vital organs were located.

01:14:06Other remains of Megalodon's victims had many bone fractures.

01:14:10This suggests that she was not shy about using her weight as a ram.

01:14:14Such a 50-ton ram could easily break through concrete walls.

01:14:18Some individuals prefer to attack the whale's tails and fins first to immobilize them,

01:14:23then attack a defenseless victim.

01:14:26This makes the Megalodon an excellent strategist.

01:14:29Megalodon's prey just didn't have a chance.

01:14:32So this shark had two main techniques, ram and ultimate bite.

01:14:37But the arsenal of T-Rex is much broader.

01:14:41Like a Megalodon, it had the strongest bite of its kind and also used a ram.

01:14:46Although its weight was not as big as Meg's, Tyreana could reach a much higher speed,

01:14:51and her impact was much more powerful than that of a shark.

01:14:55On top of that, she could strike with her tail, and her legs had a tremendous force and could hold the victim.

01:15:01No doubt the T-Rex arsenal is much more diverse.

01:15:05So this point goes to the dinosaur.

01:15:08Now it's time for the bonus category, the prize of audience sympathies.

01:15:13T-Rex is undoubtedly the most famous dinosaur of all time.

01:15:17It's appeared in movies, TV series, cartoons, video games, and even postage stamps and memes.

01:15:24And its skeleton in the American Museum of Natural History is the most recognizable in the world.

01:15:30But there are also many myths about it.

01:15:33For example, the idea that it could only see moving objects.

01:15:37In a famous movie, the heroes escape from a T-Rex by just remaining frozen in place.

01:15:43Well, first of all, a dinosaur could easily smell them.

01:15:47Secondly, T-Rex had an excellent vision.

01:15:50It was actually 13 times clearer than humans.

01:15:53Megalodon, on the other hand, has the reputation of a real devil.

01:15:58A scene where Megalodon destroys a fishing boat is still a cult favorite and frightening for viewers worldwide.

01:16:04But because there were so few remains left of it, we can only guess what it really looked like.

01:16:10So, Instagram T-Rex would be much more popular.

01:16:14T-Rex takes this point.

01:16:16Let's move forward. The score is 2 to 2.

01:16:19So the results of the battle will be decided by the last round.

01:16:23Combat tools.

01:16:25Tyrannosaurus Rex had the most powerful bite force of its kind.

01:16:29It could easily break dinosaur bones much bigger than themselves.

01:16:33But the power of their bite was limited by their teeth.

01:16:36They had a weak layer of enamel and were quite brittle, though they rebuilt quite quickly.

01:16:42Her front hands have sharp claws, but this weapon is mostly useless because of the structure of these arms.

01:16:48Megalodon has only one dangerous tool – its teeth.

01:16:53But they can be worth everything that T-Rex has.

01:16:56The teeth of the Megalodon were triangular in shape and were over 7 inches long.

01:17:01These are the most massive teeth that have ever existed.

01:17:04And it had 250 teeth, arranged in 5 rows.

01:17:08Each of them was incredibly sharp and could penetrate through the thick skin of whales.

01:17:13Also, the Megalodon's jaw was 6.5 feet wide.

01:17:17An adult person could easily fit in there, but not for long.

01:17:21Because Megalodon had one of the strongest bites on our planet.

01:17:25The gong sounds, and it means it's time to start the fight.

01:17:29These two predators meet on the coast of North America.

01:17:33Megalodons mostly lived in deep waters, but sometimes they hunted near beaches.

01:17:38T-Rex was also in this area, and now these two predators have come face to face.

01:17:44In shallow water, the Megalodon becomes even slower, and T-Rex easily evades its bite.

01:17:50But it's difficult for her to attack the shark, because Tyriana's body size does not allow her to dive underwater.

01:17:57T-Rex decides to retreat to even shallower water.

01:18:00Megan the Megalodon drops, trying to bite the dinosaur, and just rams her with all of her 50-ton weight.

01:18:07The T-Rex loses her balance and falls down.

01:18:10Now, nothing can help her.

01:18:12Uh-oh.

01:18:14So, Megalodon proves again that she was the ultimate predator and could easily defeat the world's most famous dinosaur.

01:18:23For several years, NASA's spaceship Kepler was wandering through space.

01:18:27It studied more than 150,000 stars across the galaxy.

01:18:31This search had a specific goal – to find planets that are similar to Earth.

01:18:35These planets might become our second home, but it'll happen only in the distant future, when humanity begins to colonize space.

01:18:42The mission was successful.

01:18:44Kepler found loads of planets that got called super-Earths.

01:18:48In our solar system, there's not a single planet that can be called super-Earth.

01:18:53Some scientists think it may be hidden somewhere on the edge of our system, but nobody has found direct evidence of this.

01:18:59A super-Earth sounds impressive, but in fact, it's unlikely to look anything like our planet.

01:19:05All over the universe, there are many such supers.

01:19:08To become a super-Earth, a planet must weigh from 1 to 10 times the mass of our planet.

01:19:14It also has to be twice its size and powered by a star's energy.

01:19:18That's all the criteria.

01:19:20The surface of such a planet may be rocky, or gaseous, or even mixed.

01:19:25Imagine living on such a planet.

01:19:27It's the same as ours, with similar atmosphere, climate, and landscape, but several times larger.

01:19:33Our lives are different here.

01:19:35Because of the increased mass, the gravity on this planet is much stronger.

01:19:39There are no high mountains or trees in this world.

01:19:42Everest is several times smaller.

01:19:44Most trees don't grow higher than a single-story building.

01:19:47People are also more compact.

01:19:50It's difficult for the body to grow tall when gravity presses on it with double or triple force.

01:19:55The average height of a grown-up is 3 feet.

01:19:58There are almost 8 billion people on Earth today.

01:20:01In large cities, people feel quite crowded.

01:20:04But on the Super Earth, the area is twice larger.

01:20:07People are smaller too.

01:20:08They drive small cars and live in small houses.

01:20:11That's why there's much more space.

01:20:13The air is cleaner, and not all parts of this planet are fully explored yet.

01:20:18Days and nights here last longer than on good old Earth.

01:20:22Today is Monday, and Tuesday will start in 48 hours.

01:20:25But people still don't have enough free time.

01:20:28Working hours are longer now, and people need more time to sleep, rest, and commute.

01:20:33But the cool thing is that now people are much stronger and more resilient.

01:20:37If an ordinary person gets to the Super Earth,

01:20:40they will feel as if they're carrying a heavy backpack filled with bricks.

01:20:44Their muscles won't be used to hauling such a load at all times.

01:20:47Even during sleep, they'll feel heavy.

01:20:49In an unprepared person, this pressure can damage bones and muscles,

01:20:53and lead to unpleasant consequences.

01:20:56But since people have been living on the Super Earth for thousands of years,

01:20:59they've evolved and adapted to the new conditions.

01:21:02On this planet, human bones are as strong as iron.

01:21:06Muscles are as hard as a rock.

01:21:08People are small but powerful creatures.

01:21:10But they don't know about their own strength.

01:21:12Everything around them is heavy, and this is the norm.

01:21:15Trees are sturdier, and their wood is more durable,

01:21:18which means the furniture is more massive.

01:21:21A single sheet of paper on the Super Earth can weigh 10 times more than the ones we're used to.

01:21:26The average passenger car can weigh as much as two fire trucks.

01:21:29And a teaspoon is heavier than a dumbbell.

01:21:32But since the weight of all vehicles is greater than that on our planet,

01:21:36people need more power and fuel to reach higher speeds.

01:21:39They use a lot of gasoline.

01:21:41Much more resources are needed to send rockets into space.

01:21:44It takes more fuel to overcome the gravity of Super Earth and leave its atmosphere.

01:21:49Spacecraft also have to weigh less.

01:21:52When everything is so heavy and dense, you don't feel super strong.

01:21:56But let's say you're a resident of the Super Earth and decide to visit good old Earth one day.

01:22:01You become a superhuman here.

01:22:03You can come up to any car, put your hands against its trunk, and start moving it.

01:22:08In the gym, you can easily lift any weight.

01:22:11With one strike, you can leave a crack in a concrete wall or punch through a wooden board.

01:22:16All of this looks extremely impressive, considering your small stature.

01:22:20Your legs, used to heavy loads, feel so light here.

01:22:24You can easily jump from one roof to another.

01:22:27If you accidentally fall from a two-story building, your body won't receive any serious damage.

01:22:32Your skin won't be scratched, your bones will easily withstand the fall.

01:22:36On Earth, you become a superhero.

01:22:39Unfortunately, a Super Earth with the conditions perfect for humans hasn't been found yet.

01:22:45These planets are still poorly understood.

01:22:47They can even pose a danger to people.

01:22:49A large mass means a huge amount of energy, and this energy needs to be released.

01:22:54If we lived on the Super Earth, volcanic eruptions would be as common as thunderstorms.

01:22:59The increased gravity could also cause more tectonic plates movement.

01:23:03The landscape and the planet's crust would be very unstable.

01:23:07Imagine earthquakes waking you up every day.

01:23:10Such conditions would encourage people to develop a great sense of balance.

01:23:14There would also be special technologies strengthening house foundations.

01:23:19Frequent shifts of tectonic plates would trigger huge tsunamis.

01:23:23Oceans would constantly change their shape.

01:23:25Vast areas of land would get flooded.

01:23:28In such changing conditions, people would never be able to build permanent cities and live comfortably.

01:23:33Plus, if people ever came here, it'd be difficult for them to fly away because of the planet's powerful gravitational force.

01:23:40Space objects flying past the Super Earth would be more likely to fall on the planet.

01:23:45In addition to volcanic eruptions and earthquakes, there would be frequent meteor showers,

01:23:50and those wouldn't be just tiny rocks that evaporate in the atmosphere.

01:23:54Huge asteroids could be thrown off their course by the planet's gravity.

01:23:58People would have to build a machine that could destroy meteorites before they enter the atmosphere.

01:24:03But even if they succeeded, hundreds of chunks of space rock would still fall on the Super Earth.

01:24:09After all these catastrophes, people would most likely understand that there's only one super awesome Earth,

01:24:15and it's our home planet.

01:24:18The worst thing that can happen to Earth is the hardening of its core.

01:24:22As soon as it stops working, the planet will lose the shield that protects it, and us, from space radiation.

01:24:28Solar storms and blasts of energy can create serious problems for people.

01:24:32All electronics will stop functioning normally.

01:24:35The Internet, power plants, traffic lights, computers, airplanes, you name it.

01:24:40To survive in such a place, people would have to live under a huge dome.

01:24:44It wouldn't allow radiation and meteorites to pass through.

01:24:48But many Super Earths have conditions that are even tougher than that.

01:24:52For example, there's a planet where the air temperature is so high, metals get vaporized there.

01:24:57It's unlikely any life forms can appear in such a place.

01:25:01But if people had to evolve there, our species would be invulnerable.

01:25:05Imagine creatures covered in skin that's stronger and more elastic than any material on Earth.

01:25:10Walking through fire would be as ordinary to them as breathing air.

01:25:14The inhabitants of this world would probably try to take over other planets.

01:25:18The only thing they wouldn't be able to withstand would be low temperatures.

01:25:22A light, warm breeze would seem like an ice-cold gust of wind to them.

01:25:27There's another Super Earth similar to this one.

01:25:29It receives tremendous amounts of energy from the nearest star.

01:25:32Because of this, the temperatures there are so high, they even destroy molecules.

01:25:37In the depths of space, scientists have found another Super Earth.

01:25:41It's two and a half times the size of our planet and is completely covered with water.

01:25:46There's not a single patch of land on it.

01:25:48The planet is super heavy. That's why it's tilted a bit to the side.

01:25:52When this Super Earth rotates on its axis, water flows from one side to another.

01:25:57Massive, destructive tsunamis are a common occurrence on this planet.

01:26:01If people lived there, they would look more like amphibians than humans.

01:26:05Another Super Earth is six light-years away from us.

01:26:08Its mass is three times that of our Earth.

01:26:10It takes the planet about 233 days to orbit its star.

01:26:14This planet receives only 2% of the star's energy.

01:26:17The surface of this world is a dark place, covered with ice.

01:26:21One of the most amazing planets out there seems quite friendly and potentially habitable.

01:26:26Just like our Earth, it glows with blue light.

01:26:29But its appearance is deceptive.

01:26:31On this Super Earth, winds blow at seven times the speed of sound.

01:26:35But the main danger is glass rains.

01:26:38Trillions of shards turn everything that gets in their way into powder.

01:26:42Gee, no, I'll have to pass on that one.

01:26:47You feel a bit dizzy, hanging in the air 10 floors above the ground.

01:26:52The only thing that stops you from falling is one of your palms and your shoeless feet.

01:26:57There's a crowd gathered down there in the street, far, far down.

01:27:01People, tiny like ants, keep screaming and pointing their fingers,

01:27:05supposedly at you and your precious cargo.

01:27:08The elderly lady in your arms seems frail and terrified.

01:27:12And still, her hands are surprisingly strong when they hold her cat clutched to her chest.

01:27:18The flames are raging above your head, bursting out of the windows,

01:27:21and the smoke is still burning your throat.

01:27:24It started three weeks ago.

01:27:26You're watching a football match, and your team is losing.

01:27:29After a while, you can't stand it anymore.

01:27:32You leap out of your seat and start pacing in front of the TV.

01:27:35At one point, you get so agitated that you hit the wall with your open palm.

01:27:40And you get stuck.

01:27:42Your first thoughts aren't very coherent.

01:27:44Uh, what's this sticky stuff on my wall?

01:27:47Finger by finger, you unstick your hand, examine it, touch the wall.

01:27:52A couple of minutes later, it finally sinks in.

01:27:55There's indeed something wrong, but not with the wall, with your palms.

01:28:00After a lot, and I mean it, of experimenting,

01:28:03you figure out they somehow stick to all kinds of surfaces.

01:28:07You try the floor, window panes, walls, furniture.

01:28:11You even manage to attach yourself to the ceiling.

01:28:14This last idea isn't well thought through, as it should've probably been.

01:28:18For almost 10 minutes, you're hanging next to the chandelier,

01:28:22swinging a bit, at a complete loss for what to do next.

01:28:26Once you manage to break free, you drop down on the sofa and start thinking.

01:28:30So, which animals can climb vertical surfaces and even travel upside down?

01:28:35Snails and slugs?

01:28:37But they produce mucus-like slime that helps them move.

01:28:40You stare at your palms. No gooey stuff there!

01:28:43Okay, what's next on the list?

01:28:45Spiders!

01:28:47You Google these creatures and find out the secret of their sticky success.

01:28:51It's miniscule hairs at the ends of their legs.

01:28:54These teeny-tiny hairs create countless points of contact

01:28:58between a spider and the surface it's on.

01:29:01Once again, all of your attention is focused on your palms.

01:29:04Are they hairy now? It doesn't seem so.

01:29:07But then you remember reading that the larger and heavier an animal is,

01:29:11the smaller the hairs are.

01:29:13For example, a beetle's hair is about one-tenth the width of a human one,

01:29:17but gecko's is already one-fiftieth the size.

01:29:21Can it be that your hands are covered in tiny hairs,

01:29:24but your eyes simply can't make them out?

01:29:27Then your thoughts take a different turn.

01:29:29You decide to figure out how far your newly-acquired abilities stretch.

01:29:34Can you actually walk on the ceiling?

01:29:37During a new series of experiments, you find out the following.

01:29:41The soles of your feet are as sticky as your palms.

01:29:44You start to feel dizzy after three and a half minutes of hanging upside down from the ceiling.

01:29:49You can't unstick and fall down no matter what.

01:29:53You should be more attentive not to bump your head against the ceiling fan again.

01:29:57And no, you can't fly from one wall to another like you've seen some superheroes do.

01:30:04Getting this experience hurt!

01:30:06After practicing and experimenting for hours on end,

01:30:09and ignoring seven calls from your probably most likely furious boss,

01:30:14you decide it's time to take it outside.

01:30:17Your apartment is on the fourth floor.

01:30:19Not too high, but nothing pleasant if your bizarre abilities suddenly stop working.

01:30:24You drink some orange juice to pluck up your courage and open the window.

01:30:28Cars moving along the street down there suddenly look much smaller than they did in the morning.

01:30:33Weird, huh?

01:30:35You breathe in and step forward.

01:30:38At least you aren't hurtling toward the ground.

01:30:40In fact, you're firmly stuck to the wall next to your window.

01:30:44Time to start moving.

01:30:45You've almost made it to the second floor when you decide to take a break.

01:30:49That's when you notice the face.

01:30:52It's pale, with a wide-open mouth and some strange emotion in the eyes.

01:30:56You're pretty sure that's horror.

01:30:58Ah, it must be your downstairs neighbor.

01:31:01Unfortunately, you can't tell him there's nothing to be worried about.

01:31:05The man won't hear you, and your hands are kind of occupied.

01:31:08You see your neighbor grabbing his phone.

01:31:11Duh, is he gonna call 911?

01:31:13True to form, several minutes later, you hear sirens.

01:31:17In no time, several people are using loudspeakers, trying to calm you down.

01:31:22The help is coming! Hold on!

01:31:24As if something terrible can happen to you at the height of the second floor.

01:31:28And still, soon all this situation becomes too much for you.

01:31:32You get so stressed that instead of moving down to the ground, you climb back into your apartment.

01:31:38All of a sudden, everything goes quiet.

01:31:40You hide in the bathroom and drink another glass of orange juice.

01:31:44When you crawl toward the window, half an hour later, the street below is empty.

01:31:48A week has passed, and you finally have to accept the bitter truth.

01:31:52Your downstairs neighbor is doing his best to avoid you.

01:31:55The next day, after discovering your unusual abilities, you realize you can't put it off any longer.

01:32:02You have to return to work.

01:32:04When you arrive at the office, your boss spends a good half an hour telling you off.

01:32:09After that, you're free to go and deal with a pile of working issues.

01:32:13By the end of the working day, you feel as if a diplodocus has chewed on you and then spat you out.

01:32:19But the only escape route is blocked by your boss talking to one of your colleagues.

01:32:23And it doesn't look as if they're going to finish their animated discussion anytime soon.

01:32:29But then, why would you need your super abilities if not to sneak out of places?

01:32:34You open the window and slip through.

01:32:36Oh look, you're getting better at this!

01:32:39During the next several weeks, you discover more and more uses of your wall-climbing abilities.

01:32:44For one thing, you can change light bulbs without using a chair.

01:32:48But you have to do this within three and a half minutes.

01:32:51Any longer, and you get dizzy.

01:32:53You conquer that mountaintop you've been dreaming about.

01:32:56But before, it seemed too hard for you.

01:32:59One night, you try to climb a skyscraper.

01:33:01But you get awfully tired before reaching the top.

01:33:04You save countless kittens stuck on roofs and trees.

01:33:08And now, you even have a criminal story to tell.

01:33:12One evening, a gang of muggers surrounded you.

01:33:15They were trying to get your money and phone.

01:33:17They didn't expect you to escape by climbing a smooth vertical wall.

01:33:21It scared them out of their minds.

01:33:23And then, one day, a fire happens.

01:33:26You're driving to work when you see the flames bursting out of an apartment on the 10th floor.

01:33:31Dozens of people have already gathered near the building.

01:33:34You join them and hear someone mention an elderly woman who lives in the apartment with her cat.

01:33:40You understand the time has come for you to use your abilities.

01:33:44You take off your shoes and start climbing the wall of the building.

01:33:47Your ascent is accompanied by screams and loud cheering.

01:33:51After reaching the needed window, you break it and carefully get inside.

01:33:55That day, luck is on your side.

01:33:58For one thing, the lady is really small.

01:34:00It won't be a problem to lift her.

01:34:02Even better, both she and her cat are in the room.

01:34:05Miraculously, the woman doesn't demand long explanations.

01:34:09She grabs the cat, you grab her, and in the next moment, you're all out the window.

01:34:14You successfully get to the ground, and the lady is taken away by doctors.

01:34:19And then, you get surrounded by reporters.

01:34:22An avalanche of questions and camera flashes follow.

01:34:26Lots of people have been recording your heroic descent, so it doesn't take long for you to become a superstar.

01:34:32At first, you feel shy and exposed.

01:34:35But pretty soon, you realize this kind of popularity can bring you good money.

01:34:40You're invited to numerous TV shows.

01:34:42Loads of companies want you to advertise their products.

01:34:46Illusionists and circus troops ask you to take part in their performances.

01:34:50You become world famous.

01:34:52Your face is on all magazine covers.

01:34:54You earn enough money to travel by business jets and stay in the world's most expensive hotels.

01:35:00But one year after you started walking on vertical surfaces, you wake up to a news article.

01:35:06Another person has gained the same ability.

01:35:09And every week, more and more people discover they can walk on walls.

01:35:13In several more years, it isn't considered to be such a rare ability.

01:35:17And all you can do is deal with the fact that you aren't unique anymore.

01:35:21But then, you check your bank account and smile, happy in the knowledge that, hey, you were the first.

01:35:31You're trying to sneak into the dark labyrinths of the ancient pyramids in search of immortality.

01:35:37You open the puzzle lock on the door and hear a loud rattle.

01:35:41Everything around you begins to shake and you see a huge door open.

01:35:45The room is full of gold and ancient scrolls.

01:35:48A large golden bowl falls right at your feet.

01:35:51But you kick it aside and move forward because you came here for a different purpose.

01:35:56Suddenly, you hear footsteps.

01:35:58You hide behind a pillar quickly and you see a man appear from the depths of the room.

01:36:03You're scared because the old man looks just like a living mummy.

01:36:08His skin is dry and stretched over his skeleton.

01:36:11He drags his long hair behind him like a train of a dress.

01:36:15And he's... smiling?

01:36:18The man invites you to sit next to him.

01:36:20It turns out that this old man is the last person of an ancient civilization that wanted to discover the secret of immortality.

01:36:29And they succeeded.

01:36:31Three thousand years ago, this tribe held their ritual.

01:36:35They danced around a fire and a huge cauldron.

01:36:38They caused a great storm with their dance.

01:36:41And a second later, a huge bolt of lightning struck the cauldron.

01:36:45There was a blue column of light for several minutes.

01:36:48During this time, the whole tribe continued to dance and sing.

01:36:52When the storm was over, the tribal leader came up to the cauldron.

01:36:56There were only a few drops left.

01:36:58He poured them into a flask and drank.

01:37:01The next second, his body started glowing and he felt stronger than ever before.

01:37:07It was the elixir of immortality.

01:37:10This man had recently celebrated his three thousandth birthday.

01:37:14He received all the knowledge available to a man of his time.

01:37:18He wandered the world and taught other people.

01:37:21But then, he strangely decided to lock himself in a pyramid and live in eternity alone.

01:37:27As a reward for your intelligence and dexterity, the old man gives you that very flask of elixir.

01:37:34You drink a few drops and feel a burning sensation spread all over your body.

01:37:39Your hands get tremendously powerful.

01:37:42The fire subsides and from that moment on, you are immortal.

01:37:47There's one condition though.

01:37:49You'll live forever, but your body will age infinitely.

01:37:53One day, you'll turn into a skinny old man.

01:37:57You return home and hundreds of journalists are waiting for you when you get off the plane.

01:38:02Flashing cameras, microphones.

01:38:04Now you're a real celebrity and you have to decide how to spend your endless time on Earth.

01:38:10And while your body is young, you decide to do everything you were afraid of before.

01:38:15You spend the next twenty years of your life traveling the world.

01:38:19You've been to Everest, the highest mountain in the world.

01:38:22And you've been down into the Mariana Trench, the deepest place on Earth.

01:38:26You've surfed in Hawaii and skied in the Alps.

01:38:29You've even made it to the North Pole on a dog sled.

01:38:32Finally, you've been to the International Space Station as a tourist.

01:38:36You're not afraid of anything because you know you'll live forever.

01:38:40Now you look forty years old.

01:38:43And when you go to a nightclub to dance till morning, everyone looks at you with amazement.

01:38:48But you feel so young.

01:38:50So it's time for some new hobbies.

01:38:52Breakdancing, why not?

01:38:54Oh, here's why.

01:38:56You do a stunning move and your bones crack like an old man's.

01:39:00That's because you're fifty years old now.

01:39:04It's time for a career change.

01:39:06And you decide that you need to acquire every single piece of knowledge that is available to humanity.

01:39:11It takes you ten years to get an education at the world's best universities.

01:39:16You understand how the mechanism of our civilization works.

01:39:19And you manage it.

01:39:21And now, besides immortality, you have a huge fortune.

01:39:25But you look in the mirror and you don't feel happy.

01:39:28You begin to age.

01:39:30Your hair is no longer as silky as it used to be.

01:39:33And there are wrinkles all over your face.

01:39:36But sixty years is nothing compared to the infinity you have to live.

01:39:41So now, your goal is to find a way to extend the youthfulness of your body.

01:39:46To do that, you take out your microscope and start studying the aging process.

01:39:51Our body is like a huge puzzle of big blocks.

01:39:54Those blocks are the organs.

01:39:56They're made up of smaller blocks, which are tissues.

01:39:59They group together to form a functioning organ.

01:40:02All the tissues are made up of much smaller blocks, which are cells.

01:40:06When we're young, our cells are small and active.

01:40:09They keep multiplying and renewing.

01:40:11It keeps our tissues and organs as good as new.

01:40:14But as we age, the cells lose this ability.

01:40:17They multiply less actively, increase in size, and perform poorly.

01:40:23And like old car parts, they start to malfunction and break down.

01:40:27And you get the check engine light on.

01:40:30So you work in the lab to create a potion that will make your cells keep dividing and working.

01:40:36You've spent another ten years of your life doing this.

01:40:39Now you look very old.

01:40:42But the results of your ten years of work is a failure.

01:40:46Like other scientists, you've concluded that your cells lose the ability to regenerate at a certain age.

01:40:52They can no longer compensate for the damage that various factors do to us.

01:40:57It was for this reason that the 3,000-year-old chief of the ancient tribe decided to hide in the pyramid.

01:41:04He isolated himself from any outside damage so that his body wouldn't be exposed to any danger.

01:41:10Locking yourself up in a safe place seems like the only way out.

01:41:15The air in the pyramid has no harmful bacteria, but was so dry that it turned the old man's body into a real mummy.

01:41:23Your money could allow you to build quite a posh greenhouse.

01:41:27So the inside of your mansion is lined with airtight plastic sheeting to protect you from bacteria.

01:41:33Every piece of interior furniture is now in its own film.

01:41:37You'll also have to wear a sealed spacesuit on Earth with a tank of purified air.

01:41:42And most importantly, several helicopters lower a glass dome onto your house.

01:41:48Now this aquarium is your home forever.

01:41:51Literally forever.

01:41:53All of your guests and employees in the house must also wear airtight suits so as not to infect you with anything.

01:42:00Oh, it's dinner time!

01:42:02A few tubes of food.

01:42:04It looks disappointing.

01:42:06The thing about food is that there are bacteria and germs in it.

01:42:10Usually our bodies fight them easily, and we enjoy a burger without thinking about the problems.

01:42:15But your body might not be able to handle it.

01:42:18So from now on, you have to eat only specially processed food.

01:42:22A couple of decades later, you'll only be eating nutritional solutions to keep your stomach out of danger.

01:42:29But you can still go out for a walk.

01:42:31For that, you'll need an airtight bubble with a wheel, like the one that hamsters play with.

01:42:36You can walk the streets and admire your hometown, which gradually begins to resemble a futuristic movie.

01:42:43Neon signs, flying cars, holograms, and robots everywhere.

01:42:48Hey, hey, it's your 200th birthday!

01:42:51And your gift to yourself is a special flying vehicle in which you can travel around the world safely without touching anyone or anything.

01:43:00All this technology has made you feel young again.

01:43:03But your face is sad.

01:43:05It's all about your brain.

01:43:07It ages like the rest of your body.

01:43:09And our brain, like a computer, has a memory limit.

01:43:13All your busy life, all your surfing and skydiving, they're all recorded on that computer as video files.

01:43:20And there are too many of those files out there.

01:43:22And when you record a new event in your brain, it deletes something old and unnecessary from your memory.

01:43:28For example, the formula for finding the area of a trapezoid.

01:43:33Naturally, you want to expand your memory.

01:43:35You can insert an extra flash drive in your brain.

01:43:38Ah, that solves the problem for the next few decades.

01:43:42But your body continues to age.

01:43:45In the year 2300, you read the news about a scientific breakthrough.

01:43:50They've created a computer you can transfer your consciousness to.

01:43:54And now, that computer is in your house.

01:43:57But you're scared.

01:43:59Our identity is our memories and our thoughts.

01:44:02And if you transfer them to a computer, will you still be you?

01:44:06Or will it be just a copy of you?

01:44:08And then, what happens to you as a person?

01:44:11Fear and hopelessness take over you.

01:44:14Immortality is both a great gift and a great burden.

01:44:18You're all alone.

01:44:19Your family and friends aren't here with you 200 years after you became immortal.

01:44:24All you have now is an abnormally old body.

01:44:27And you're kind of angry at yourself for being immortal.

01:44:31April 10th, 1912.

01:44:33You're on the coast of the Atlantic Ocean in a small port town.

01:44:37Hundreds of people, and you among them, are going to board the huge majestic ship.

01:44:42It's three times as long as the Statue of Liberty is tall.

01:44:46The ship is considered the most advanced and unsinkable watercraft of its time.

01:44:50You can see hundreds of luxury cabin windows on its deck.

01:44:53And the Titanic inscription on the magnificent iron hull.

01:44:58This day, the famous superliner set off on its first and last voyage from Southampton to New York.

01:45:05But now, you'll see an alternate story.

01:45:10You can hear a crew member announcing the start of the Titanic's trip.

01:45:14The ship sails from Africa to Bermuda.

01:45:17And the cause of its catastrophe will not be an iceberg at all.

01:45:21For four days, Titanic sails through North Atlantic waters.

01:45:25The sun warms the ship so much that during the day, all the passengers sit inside the ship.

01:45:30In the evening, when a cool breeze descends on the ocean, all the people go up on deck to watch the beautiful red sunset.

01:45:38Midnight, April 15th.

01:45:40You're sitting in your cabin reading a book.

01:45:42You're usually asleep at this time, but right now, you're just flipping through page after page.

01:45:48You close the book and look around the cabin.

01:45:50You feel like someone's watching you.

01:45:52You get up and break out into a cold sweat.

01:45:55An inexplicable feeling of anxiety permeates your body and causes goosebumps.

01:46:01You look out the cabin window where the ocean spray is banging the glass, but you can't see anything.

01:46:07There's a thick fog outside.

01:46:09You leave the cabin.

01:46:10In addition to you, several passengers also left their beds because of a heightened sense of danger.

01:46:16They greet you and ask what's wrong, but no one knows.

01:46:20You head to the stairs to go out on the deck to see the situation.

01:46:24At this point, the floor goes out from under your feet.

01:46:27A strong push makes you fall.

01:46:29A rumble reverberates through the Titanic.

01:46:32You get up and see more and more people going out from their cabins.

01:46:36You run up the stairs and meet a crew member.

01:46:38He doesn't tell you anything, but his eyes are wide with fear.

01:46:42You go up on deck and can hardly see anything.

01:46:45A thick, wet fog has settled over the ship.

01:46:48Several passengers are holding their heads as if they have a headache.

01:46:51You see the captain and ask him what happened.

01:46:54The captain admits that he has no idea where you are.

01:46:57You see a compass in his hand.

01:46:59The arrow turns in different directions.

01:47:01It's impossible to determine where exactly the ship is now.

01:47:05Interestingly, there was no such thing as the Bermuda Triangle before 1964,

01:47:10but the first reports of missing ships in this area date back to the middle of the 19th century.

01:47:16Another push.

01:47:17This time you've managed to stay on your feet.

01:47:19It felt like something big just hit the ship.

01:47:22You run to the railing at the edge of the deck and stare overboard.

01:47:26Through the white fog, you notice a huge shark fin.

01:47:29You haven't seen the full size of the shark,

01:47:32but from what you've seen, it must be as long as a train car.

01:47:36The shark swims away, but after a few seconds, you can see its fin again.

01:47:40It quickly approaches the ship and grabs the iron hull with its huge jaws.

01:47:45The deck is shaking.

01:47:47You can hear the grinding of metal.

01:47:49It seems this huge predator just made a hole in the hull.

01:47:53Only one creature on the planet can do this.

01:47:55The Megalodon.

01:47:57It's an ancient marine predator that measured almost 60 feet in length.

01:48:01Megalodon had no competition in the ocean.

01:48:04It was at the top of the food chain.

01:48:06It's believed the shark disappeared millions of years ago,

01:48:09but the ocean is only 5% explored.

01:48:13Here, it's alive and swimming in the mysterious waters of the Bermuda Triangle.

01:48:18Everyone aboard the ship is panicking.

01:48:21People from the lower decks are running upstairs.

01:48:23The Titanic slowly sinks and tilts to the side.

01:48:27Everyone goes to the lifeboats,

01:48:29but no one dares to get in them while the huge ancient monster is around.

01:48:33The ship's bow submerges under the water.

01:48:36You stand on the left side of the deck

01:48:38and see the Megalodon bite off pieces of the iron hull.

01:48:42You shout to the people in the stern section that the Megalodon is busy

01:48:46and they have time to evacuate.

01:48:48The first rescue boats with passengers go down on the water.

01:48:51Some passengers just jump overboard.

01:48:54Fortunately, the water is much warmer than the place where the Titanic actually sank.

01:48:59You put on a life jacket and jump too.

01:49:02The Megalodon attacks the ship and drags it deeper into the water.

01:49:06The smell of the Titanic's kitchen must have attracted it.

01:49:09You find yourself among the ship's flotsam and lifeboats.

01:49:13The fog's finally rising.

01:49:15The starry sky and the moon illuminate the sea's surface.

01:49:18People help you to climb on board a rescue boat.

01:49:21Everyone tries to sail as far away from the sinking ship as possible.

01:49:25You see the huge shark swimming around the Titanic.

01:49:28At this moment, something distracts it and the predator goes away.

01:49:32More than half of the ship is already under the surface.

01:49:35The second part looks like a candle sticking out of the water.

01:49:38The ocean is calm. The sky is clear and cloudless.

01:49:41There's no wind.

01:49:43From the side, you see a huge wave growing behind the Titanic.

01:49:47It's about 50 feet high, like a five-story building.

01:49:51It knocks the ship down as easily as if it was made of paper.

01:49:55The monster wave dissolves in the water as quickly and unexpectedly as it appeared.

01:50:00You've just witnessed a rogue wave.

01:50:03This phenomenon occurs all over the world.

01:50:06Enormous waves suddenly appear, demolish ships, and disappear without a trace.

01:50:11Scientists still can't determine their exact nature.

01:50:14But according to the most popular theory, these waves are formed by kinetic vampirism.

01:50:20Under certain natural conditions, waves accumulate and exchange kinetic energy.

01:50:25Among all the waves out there, there is one vampire wave that absorbs the energy of all the others.

01:50:32When a lot of energy is accumulated, a huge wave grows and splashes it all out.

01:50:38Some believe the frequent disappearance of ships in the Bermuda Triangle occurred because of rogue waves.

01:50:44The people on the boats calm down.

01:50:46Someone sends a flare into the sky.

01:50:48You look at the ocean and see the triangular fin of the Megalodon emerging from the water.

01:50:54It's the size of a sailboat, and it's coming your way!

01:50:58You row the oars as fast as you can.

01:51:00People are screaming and calling for help.

01:51:02There's no chance of escape.

01:51:04The legendary monster is getting closer and closer.

01:51:08The shark's head peeks out from under the surface.

01:51:10It opens its huge maw filled with hundreds of sharp teeth.

01:51:14Each of them is the size of your palm.

01:51:17The boat will fit entirely inside the shark's mouth.

01:51:20It can swallow you whole.

01:51:22The shark stops and closes its mouth at arm's length from the boat.

01:51:27You can see the water bubbling around you.

01:51:29From the ocean depths, several giant tentacles lash out and wrap around the Megalodon.

01:51:35They pull the shark down.

01:51:37You look over the side and see a purple glow with a black circle in the center.

01:51:42Someone on the boat notices it too.

01:51:45People start screaming,

01:51:46It's looking at us!

01:51:48A woman shouts.

01:51:49After a second, you get goosebumps, and a shiver runs through your entire body.

01:51:54This purple glow is something's eye, and the black circle is the pupil.

01:52:00The creature that is looking at you right now is so big that the boat seems like a grain of rice to it.

01:52:06It's the Kraken!

01:52:08The giant squid, an ancient monster that sank hundreds of ships,

01:52:13but whose existence has not been proven by anyone yet.

01:52:16Fortunately, the boat you're sitting in is too small to interest the Kraken.

01:52:21You can see its eye moving deeper away.

01:52:24Huge tentacles pull the struggling Megalodon into the depths.

01:52:28An hour passes, and another big superliner arrives at the wreck of the Titanic.

01:52:33All the passengers are rescued.

01:52:35You look back at the calm sea, at the place where the Titanic recently sailed.

01:52:40You climb aboard the rescue ship and promise yourself never to go on a sea voyage again.

01:52:47You've finally done it!

01:52:49You've created a simulator that allows you to copy yourself into the apps on your phone to learn faster.

01:52:55You plug your phone in, open Google, and put on a helmet with goggles to get a 360-degree view.

01:53:01After hooking them up, you call your sister to activate the machine.

01:53:07She's not answering you, so you head to her bedroom, where you see her doing a TikTok dance challenge.

01:53:13You tease her for it and pester her to activate the machine downstairs.

01:53:17She follows you while still using TikTok.

01:53:20She gets upset and, without you looking, changes the homepage on your phone to TikTok.

01:53:26She then activates the machine.

01:53:30You're in the simulation, but something's wrong.

01:53:33You're going through a virtual wormhole.

01:53:35You see all kinds of apps circling you until you land flat on your face on a dark surface.

01:53:43You're scared. Your heart is thumping.

01:53:45You look around and see yourself in a room with a screen in front of you.

01:53:50It asks for your username.

01:53:52You shout all kinds of words, asking to let you out, but a red light blinks every time you do so.

01:53:58Every word you say is picked up by the screen, which then displays it as your username, while asking you to accept it to proceed.

01:54:06You say accept, and the wall opens.

01:54:09Your username is LetMeOut.

01:54:13You exit and enter a futuristic city glittered with purple and blue lights and tall towers with screens showing TikTok videos nonstop.

01:54:23The tallest tower shows the most trending videos today.

01:54:26We'd like to continue helping you learn and giving you useful skill improvement tips.

01:54:31Got a thirst for knowledge?

01:54:33We've prepared four masterclasses on creating a 2D character animation from scratch,

01:54:3810 hours of video lessons, practical tasks using professional software, and additional materials that you can use with your own projects.

01:54:46While the other towers show other popular videos, you follow the road in front of you.

01:54:51It leads you into a crowd in the middle of a virtual Times Square.

01:54:55Everyone has a floating bubble above them with their username and bio written there.

01:55:00It also shows how many followers they have.

01:55:03Most of these people have just a handful of followers.

01:55:06They look like their profile pictures.

01:55:08Everyone is staring at you, since you're the only one who looks not like an avatar, but like a real human.

01:55:17You see two people standing opposite each other without moving.

01:55:20You see the bubbles above each of them change.

01:55:23They are now following each other.

01:55:25Suddenly, everyone stops and stares at the girl as she becomes verified.

01:55:31A blue tick appears in her bubble, and she vanishes.

01:55:35You run up to the one who has just followed her and try to get some information.

01:55:39You're the only one talking out loud, while everyone else is communicating through direct messages in their inboxes.

01:55:46You realize that you have to stand still and wait for someone to accept your DM.

01:55:51The person you're talking to receives your message and blocks it.

01:55:55You try to initiate another dialogue, but the person freezes and then walks away.

01:56:02You realize some people are looking at you in a peculiar way.

01:56:05They start following you.

01:56:07They're everywhere.

01:56:08You start walking fast and disappear into a sea of people where they can't find you.

01:56:15After a while, you dip into an alley and find an underground cafe.

01:56:19You enter and see a bunch of people sitting around doing nothing.

01:56:24You try to talk to some of them, but they don't answer.

01:56:27Even weirder, they don't have faces.

01:56:29None of them have followers.

01:56:31They don't respond to anything.

01:56:33And if you try to communicate with them, they just spaz out some advertisements.

01:56:40You look at the screen in the room.

01:56:41It shows your face.

01:56:43TikTok is after you.

01:56:45You hear a knock on the door, and dozens of people rush in.

01:56:49They're the internal security of TikTok, and they're after you.

01:56:53You exit through another room.

01:56:55Now you're inside a building where many of these bots are living.

01:56:59They're behind you and getting closer.

01:57:01You reach a dead end with a window in front of you.

01:57:04You turn around and see the security running straight at you.

01:57:09You have no choice but to jump out of the window.

01:57:13You get a running start and sprint through the glass.

01:57:16You land on the roof of a neighboring building.

01:57:19Every tower is now displaying your username and profile pic as wanted.

01:57:24You have no idea why they're after you.

01:57:28You make your way to another alley and hide in a dark corner.

01:57:31It seems you've lost them.

01:57:33You check your settings to see why you're the most wanted man on TikTok.

01:57:38It shows that you're an invalid user.

01:57:41The app thinks you're a glitch that's going to destroy the very fabric of TikTok.

01:57:47You know for a fact that it's just the cybersecurity of TikTok working to catch any bugs or attacks.

01:57:53You open your settings but you can't do anything since they blocked you.

01:57:57You open search and type in your sister's name.

01:58:00It turns out she's verified with a blue tick which will be difficult to track.

01:58:06You head back out and try to search for her.

01:58:08You hear some people walking around and quickly leave the alleyway.

01:58:12You get back to the crowd.

01:58:14You can't act hysterically anymore or you'll draw attention to yourself.

01:58:19You reach Hashtag Avenue where all the trending videos are.

01:58:23So far no one has noticed you.

01:58:25The most popular hashtags are at the top.

01:58:28It's quite a walk to get there.

01:58:30You browse through most of them but can't find your sister.

01:58:33Then you remember that she was dancing.

01:58:36So you check the hashtag dance and try to locate her.

01:58:40You find out that the video she was doing earlier is one of the most popular videos.

01:58:45You finally find her but the security stops you and chases you along Hashtag Avenue.

01:58:51You randomly appear in various trending videos.

01:58:55You reach a dead end and the security catches you.

01:58:58They escort you to a room where they try to get information out of you.

01:59:02They think you're a bot.

01:59:04But you keep telling them that you invented the machine to copy yourself into TikTok virtually.

01:59:09They're not buying it.

01:59:11Eventually they try to extract you but it's not working.

01:59:14They try to figure out what to do but they don't let you leave.

01:59:18While they're transporting you to another facility,

01:59:20you manage to slip out of their sight and sneak off to search for your sister.

01:59:25This time you have to be on high alert.

01:59:29TikTok is searching for you.

01:59:31Users have seen you in hashtags so they're also on the lookout.

01:59:35Out of nowhere, large cameras pop out.

01:59:38They're trying to spot you.

01:59:40You slip up and you could be stuck in TikTok for good.

01:59:45You make one last attempt to get to your sister.

01:59:48You find a hat and a jacket to disguise yourself.

01:59:51Now it's impossible for you to interact with anyone since they can detect your activity.

01:59:56But you have to take this chance for her to get you out.

02:00:01Eventually you go back to Hashtag Avenue and head to your sister.

02:00:05You find some of the most popular TikTokers chilling together.

02:00:08Your sister is among them.

02:00:10There's a lot of security so you keep it low.

02:00:13After a while, you slowly approach her and take her aside.

02:00:17You activate the chat option and ask her to head downstairs to the basement

02:00:21and unplug you from the system.

02:00:24But before you can finish the last few words,

02:00:27the security guards rush over to you and start chasing you.

02:00:31But this time all cameras are on you and there's no place to go.

02:00:35You surrender yourself to the security and they take you to a locked room you can't escape from.

02:00:41You sit there worried.

02:00:42You're bouncing your knees and rubbing your palms together.

02:00:45You have no idea if your sister has received the full message or not.

02:00:51Hours pass and no word from outside.

02:00:54You may have blown it.

02:00:56But suddenly you get a notification from your sister.

02:00:59You try to type but nothing is working.

02:01:01You start feeling funny.

02:01:03Everything around is shaking.

02:01:05The walls start glitching and you see the real world.

02:01:09You get pulled into a wormhole and you wake up in your lab.

02:01:15You're breathing heavily, trying to piece the recent events together.

02:01:19You feel like you've been in TikTok for half a day.

02:01:22But apparently it was less than half an hour.

02:01:25Your vision is clear and the first thing you see is your sister filming you with her phone.

02:01:30She's grinning from ear to ear, not knowing what you've actually gone through.
