00:00Have you heard about a diamond star that could put all the riches on Earth to shame?
00:05Or how about twinkling stars with surfaces made of solid iron?
00:09So let's take a look at these weird stars and try to unravel their mysteries.
00:16There's a star in the Centaurus constellation that was nicknamed Lucy in the Sky with Diamonds.
00:22Yes, it was named after a Beatles song, because it basically is a Beatles song.
00:27You see, the star was discovered to have a massive diamond at its core.
00:35Now, you may be wondering how big this diamond really is.
00:39Well, it's estimated to be about 10 billion trillion trillion carats.
00:45That's a one followed by 34 zeros.
00:48To put that into perspective, the Hope Diamond, which is one of the largest diamonds on Earth,
00:53is a measly 45.5 carats in comparison.
00:57Can you imagine the size of the ring you could make with this star diamond?
01:02And it's about the same mass as our sun.
01:06But don't get too excited about the prospect of owning this diamond just yet.
01:11Even if you were Jeff Bezos, you wouldn't be able to afford it.
01:15According to Ronald Winston, CEO of Harry Winston, Inc.,
01:19the diamond is so big that it would likely depress the value of the market.
01:24So you'd have to settle for a much smaller diamond engagement ring.
01:30One interesting thing about the Lucy in the Sky with Diamonds star is that it's incredibly dense.
01:36In fact, it has the mass of the sun crammed into an object only a third the diameter of Earth.
01:43That's like trying to fit an elephant into a shoebox.
01:46And yet, despite its massive size, it's actually quite cool,
01:51with a core temperature of only about 12,000 degrees Fahrenheit.
01:55By comparison, the core temperature of our sun is about 27 million degrees Fahrenheit.
02:03Since the discovery of Lucy in the Sky with Diamonds,
02:07several other crystallized stars have been found,
02:09some with diamond hearts the size of Earth.
02:13It just goes to show that the universe is full of surprises.
02:16And you never know what kind of treasures you might find out there in the vast expanse of space.
02:23And this isn't the only weird star we've discovered so far.
02:27There are many strange, unexplained things in outer space.
02:33For example, let's take Vega.
02:36Vega, also known as Alpha Lyrae, is a bright star located in the constellation Lyra.
02:42It's one of the brightest stars in the night sky,
02:45and is easily visible to the naked eye from most parts of the world.
02:51Now, Vega may look like a beautiful, bright star to us Northern Hemisphere folks.
02:56But little do we know, it's hiding a secret.
03:00It's actually quite squashed.
03:03You see, Vega's high spin rate causes it to bulge at the equator,
03:08kind of like a cosmic belly.
03:10It rotates once every 12.5 hours, which is pretty fast for a star,
03:15and it throws material out around its waistline.
03:19It's almost like the star is hula-hooping.
03:22This material is further from the center of the star,
03:25so it experiences less gravity, causing it to cool and darken,
03:30leading to a gravity-darkening effect.
03:34So Vega is basically a cosmic fitness guru's worst nightmare.
03:40Although for us stargazers, it still looks round,
03:43because we're looking at it from Earth's pole end.
03:46However, if we saw it from a different angle,
03:49we'd get a very different view,
03:51one that might make us wonder
03:53if Vega has been sneaking some cosmic donuts behind our backs.
03:58But while we might joke about its equatorial waistline,
04:02there's no denying that Vega is still one of the brightest
04:06and most fascinating stars in our galaxy.
04:10But if you want something actually bright,
04:13then how about a supernova?
04:18Supernovas are giant space booms
04:21that occur when stars reach the end of their life cycle.
04:24It's like the grand finale of a firework show,
04:27but on a cosmic scale.
04:29They release more energy in a few seconds,
04:32than our sun will produce in its entire lifetime.
04:36And this is exactly what happened to the next star of our show.
04:41This celestial object with a weird name,
04:44IPFT-14HLS.
04:47But there's a catch.
04:49It isn't your average supernova.
04:51Even though this star made a blast in 2014
04:54and started to fade away like usual,
04:58recently it made an unexpected comeback
05:00and brightened once more.
05:02Talk about a dramatic entrance.
05:06And if that wasn't enough,
05:08this thing continued to fade and brighten
05:10at least five times in total,
05:12which is a bit like a yo-yo.
05:14It's like the star just couldn't make up its mind
05:17about whether it wanted to stay bright
05:19or fade away into the abyss.
05:23Also, when scientists measured the supernova's spectrum,
05:26they found that it was evolving
05:2810 times slower than other stars.
05:31Maybe it's a supernova
05:33that just wants to enjoy its golden years.
05:37All in all,
05:38this object is a real mystery.
05:43But this is not the only star
05:45suffering from the 2-in-1 syndrome.
05:48At first glance,
05:49M.Y. Camelopardalus
05:51appears to be a fairly common star.
05:54But after a closer look,
05:56astronomers concluded
05:57it was actually two stars in one.
06:01These two stars are orbiting each other
06:04at over 600,000 miles per hour.
06:06It's a contact binary star system,
06:09which means that the stars are so close together
06:12that they share a common envelope.
06:14In other words,
06:15they're so close to each other
06:17that they're practically smooching.
06:21These celestial Romeo and Juliet
06:23are one of the most massive known binary stars out there.
06:27Each of them individually weighs in
06:29at a whopping 32 and 38 solar masses, respectively.
06:36Astronomers also think
06:37that they might be on the brink
06:38of a stellar merger,
06:40which means that one day
06:42they might just combine
06:43into one giant superstar.
06:46Wow, who knew space could be so romantic?
06:51Next, introducing another long name,
06:55HD 140283,
06:57also known as Methuselah's star.
07:00This little guy in the constellation Libra
07:02has been around for a while.
07:04And by a while,
07:05I mean a really long time.
07:08Actually, scientists used to think
07:10it was older than the universe itself.
07:15Just imagine if it turned out to be true.
07:17But eventually,
07:18they figured out
07:20that it's actually around 14.8 billion years old,
07:23a peer of our universe.
07:26That's still pretty impressive, though.
07:27This star is so old,
07:30it remembers when the Milky Way
07:32was just a baby galaxy.
07:35But despite all that,
07:37this star still has some life left in it.
07:40It's just starting to expand
07:42into a red giant,
07:43which is kind of like
07:44when you hit your 30s.
07:46Talk about aging well.
07:49But if all these things
07:51are somewhat comprehensible,
07:52then how about a star
07:54that was literally named
07:56WTF star
07:57by scientists?
07:58No, I'm not kidding.
08:00At least,
08:00it used to be.
08:02Now,
08:02it's called
08:03Tabby's star.
08:04It also has a more scientific name,
08:06but that one is a bit of a mouthful.
08:11But what's really bizarre
08:12about this star
08:13is its irregular dimming.
08:15For some reason,
08:16it doesn't glow
08:17like a normal star,
08:18but blinks,
08:19as if someone turned
08:21on and off a flashlight.
08:22And it's not just a little dip.
08:24We're talking
08:25up to a 22% drop in light.
08:28So it's not because
08:29it sometimes gets blocked
08:30by a planet or something.
08:34Scientists have come up
08:35with all sorts of explanations
08:37for this strange behavior,
08:38from comets to dust
08:40to even an extraterrestrial
08:42megastructure.
08:43That's right.
08:44But before your imagination
08:46runs too wild,
08:47it's important to note
08:48that the most likely explanation
08:50is just plain old dust.
08:52Perhaps the star
08:53is surrounded
08:54by some kind of dust cloud,
08:55and sometimes
08:56it prevents us
08:57from seeing it clearly.
09:01Although this explanation
09:02is still not 100% confirmed,
09:04there are still plenty
09:06of mysteries
09:06surrounding Tabby's star.
09:08One thing's for sure,
09:10it may be a bit of an oddball,
09:11but that's what makes
09:13it so fascinating.
09:15So,
09:16there you have it, folks.
09:17We're left in awe
09:19of the incredible diversity
09:21and strangeness
09:22of the cosmos.
09:23There's so much more
09:24to discover out there.
09:25So, let's keep exploring
09:27and keep being amazed
09:29by the wonders of...
09:30Ah, consider the rogue planet,
09:32the cosmic wanderer
09:34that nobody wants
09:35to take home.
09:36Basically, a rogue planet
09:37is a planet
09:38that has been ejected
09:39from its own star system
09:41and is now floating
09:42aimlessly through space
09:44like a cosmic loner.
09:46These planets aren't
09:47just a theory.
09:48Scientists have actually
09:49detected some
09:50in our galaxy.
09:51In fact,
09:52estimates suggest
09:53that there may be
09:54lots of these
09:55cosmic nomads
09:56floating around
09:57the Milky Way.
09:58And they aren't just
09:59small rocky worlds
10:00like Earth.
10:01Some of them
10:02are actually
10:02massive gas giants
10:04many times larger
10:05than Jupiter.
10:06These behemoths
10:07could potentially
10:08have their own moons
10:09and even their own
10:11mini-systems
10:12orbiting around them.
10:13For example,
10:14one of the most
10:15famous rogue planets
10:16we know of
10:17has a complicated name.
10:19Here, you read it
10:20for yourself.
10:21It's located about
10:2280 light-years
10:23away from Earth,
10:24and it was discovered
10:25in 2013.
10:26This rogue planet
10:28is estimated to be
10:29around 6 times
10:30the mass of Jupiter
10:31and is believed
10:32to be around
10:3312 million years old.
10:34And yes,
10:36just because
10:36these cosmic loners
10:38don't have a star,
10:39it doesn't mean
10:40they're super cold.
10:41They can still
10:42generate heat and light
10:43from their own
10:44internal processes.
10:45Some may even
10:46have magnetic fields
10:47and auroras
10:48just like Earth.
10:49In other words,
10:51rogue planets
10:51could potentially
10:52be habitable
10:53if they have
10:54the right conditions.
10:55So,
10:56what would life
10:57on such a planet
10:58look like?
10:59And could we
11:00potentially live
11:01in such a world?
11:02Well,
11:03living on a rogue planet
11:04can be a lonely existence.
11:06They have no warm sun
11:08to bask in,
11:09no cozy atmosphere
11:10to cuddle up in,
11:11and no cosmic neighbors
11:13to have barbecue with.
11:14That's why
11:15we'd have to get creative.
11:17Let's start with
11:18the most obvious problem.
11:19We'd have a hard time
11:21without light and heat.
11:22So,
11:22how do we fix this?
11:24Well,
11:25we'd probably have to invest
11:26in some really fancy
11:27space heaters
11:28and wear fashionable
11:30super-warm spacesuits.
11:31Or,
11:32we could invent
11:33a whole new way
11:34to generate electricity
11:35without relying
11:36on solar power.
11:37For example,
11:39how about using
11:39geothermal energy?
11:41Now that's hot stuff!
11:42Each planet
11:43has an internal
11:44source of heat.
11:46Without it,
11:46they would all be
11:47nothing more than
11:48cold,
11:49lifeless rocks
11:50floating through space.
11:51This internal heat
11:53can be harnessed
11:53and used to power
11:55everything,
11:55from homes
11:56to factories
11:57to spaceships.
11:58It's like having
11:59a hot tub
12:00big enough
12:01to power
12:01an entire city.
12:02And that city,
12:04most likely,
12:04will be located
12:05underground,
12:07closer to the
12:07heat source.
12:08And as for light,
12:10well,
12:11we'd probably have to
12:11build some really
12:12bright flashlights.
12:14Or maybe even learn
12:15to genetically
12:16engineer some
12:17bioluminescent
12:17organisms
12:18to light up
12:19our homes.
12:20Just imagine,
12:21space space is
12:22overgrown with
12:23neon mushrooms
12:24and plants.
12:25By the way,
12:26speaking of plants,
12:27plant life would be
12:28pretty hard to come by
12:29without a star.
12:30So,
12:31what would we eat?
12:32Well,
12:33we could use
12:34the same geothermal vents
12:35that we talked about
12:36or some chemical reactions
12:38to sustain ourselves.
12:39And hey,
12:40maybe we'd develop
12:41a taste for
12:42sulfur-rich foods.
12:43Or we'd start
12:44fermenting our own
12:45drinks from the
12:46bubbling volcanic mud.
12:48Yum!
12:50But,
12:50besides food,
12:51we'd have a more
12:52important problem.
12:53Living on a rogue planet
12:55would be breathtaking.
12:56Literally.
12:57We'd have no air.
12:59You see,
12:59not all rogue planets
13:00have good,
13:01stable atmospheres.
13:02It all depends on
13:03their size,
13:04composition,
13:05and other things.
13:06But even if
13:07our new home
13:08does have an atmosphere,
13:09it may be incredibly
13:11thin and unstable.
13:12We'd have no
13:13pretty blue skies
13:14or dramatic sunsets
13:16to admire.
13:17Instead,
13:18we'd be staring out
13:19into the infinite
13:20void of space,
13:21where the stars
13:22would be brighter
13:23than ever before.
13:24And forget about
13:25weather patterns.
13:26Without an atmosphere
13:27to create them,
13:28we'd have no rain,
13:29no snow,
13:30and no thunderstorms.
13:32And that's just
13:33some minor problems.
13:34What's worse,
13:35the temperature
13:36on the planet
13:36would be wildly
13:37fluctuating,
13:38swinging from
13:39unbearable heat
13:40to unbearable cold.
13:42It would be like
13:43living in an oven
13:44that's always being
13:44turned on and off.
13:46And finally,
13:47we'd be exposed
13:48to all kinds of
13:49space debris
13:50and cosmic radiation.
13:52So,
13:52if you don't want
13:53to get crispy,
13:54you might want
13:55to invest
13:55in some serious
13:56SPF.
13:58So,
13:58how do we fix it?
13:59Well,
14:00we'd have to
14:01find a way
14:01to generate
14:02our own oxygen
14:03and probably
14:04create something
14:05like a space-age
14:06biosphere.
14:07For example,
14:08we could grow
14:09some plants
14:09that could
14:10produce oxygen.
14:11Or we'd learn
14:12to filter the air
14:13like a high-tech
14:14air purifier.
14:15Finally,
14:16we have the last
14:17most important problem,
14:19finding water.
14:20And here's where
14:21the underwater oceans
14:22come to our aid.
14:23Now,
14:23we're really diving
14:25deep into the
14:25possibilities.
14:26Nyuk, nyuk.
14:27But seriously,
14:29scientists suggest
14:30that some of these
14:31planets may indeed
14:32have underwater oceans.
14:34It would be like
14:35living on a giant
14:36water balloon
14:36that's been buried
14:37underground,
14:38with the ground
14:39beneath your feet
14:40made of ice and rock.
14:41In other words,
14:43we could just tap
14:44into these
14:44underground oceans.
14:45They could provide us
14:47with a source of water
14:48for drinking,
14:48farming,
14:49and manufacturing.
14:50Maybe even
14:51with some other
14:51resources and materials
14:53we've never seen before.
14:54And, by the way,
14:56who knows what kind
14:57of strange creatures
14:58might be lurking
14:59in those underground seas.
15:01But don't worry.
15:03Even if we don't have
15:04any underground oasis,
15:05there are also
15:07other options.
15:08We could get some water
15:09from comets,
15:10ice mining,
15:11and even from the atmosphere,
15:12the one we just created before.
15:15Finally,
15:15we need to find
15:16and mine some resources
15:18to build our homes
15:19and other stuff.
15:20And a rogue planet
15:21might not have
15:22the same kinds of resources
15:24as a planet
15:25that orbits a star.
15:26It's like trying
15:27to find some treasures
15:28in a desert.
15:29Not exactly a sure thing.
15:31We may have to rely
15:32on resources
15:33from nearby asteroids
15:35and things like that.
15:36And if we want
15:37to extract resources
15:38from the planet itself,
15:40we might need
15:41to drill down
15:41through miles
15:42of ice and rock.
15:43But hey,
15:44if you're up
15:45for the challenge,
15:46there'll always be a chance
15:47you'll strike it rich
15:48on a rogue planet.
15:49And who knows?
15:51Maybe you'll discover
15:52some new resources
15:53that are even more valuable
15:54than gold or diamonds.
15:56Great!
15:57Looks like we've solved
15:58the most important problems.
16:00Now,
16:00there may be
16:01other small difficulties.
16:02For example,
16:03we'd also have to deal
16:05with some seriously
16:06long days and nights,
16:07depending on how fast
16:08our planet was rotating.
16:10And we wouldn't have
16:11a normal,
16:12regular day-night cycle.
16:13The rotation of our planet
16:15could be wildly unpredictable.
16:17Maybe we'd have
16:18weeks-long nights,
16:20followed by weeks-long days,
16:21which could really mess
16:23with our sleep schedules.
16:24We might have to develop
16:25some really strong coffee
16:27to keep us going
16:27through those long,
16:28dark nights.
16:29But,
16:30hypothetically,
16:31we can adapt
16:32to all these things
16:33and overcome
16:34all the challenges.
16:35And now,
16:36finally,
16:37welcome to the rogue planet,
16:39where the sun never rises,
16:40but the adventures
16:41never end.
16:43Thanks to our
16:43advanced technology,
16:44we've managed to create
16:46a comfortable
16:46and habitable environment
16:48in this once-barren world.
16:50The sky above us
16:51is now a beautiful
16:52shade of blue,
16:53filled with fluffy white clouds
16:55and the occasional flock
16:57of flying creatures.
16:58Don't ask.
16:59As we venture out
17:01from our underground habitats,
17:03we're greeted by a world
17:04that's full of surprises.
17:06Strange plants and animals
17:07have adapted
17:08to the unique conditions
17:09of this planet,
17:10some with bioluminescent features
17:12that glow in the dark.
17:14And be careful
17:15if you want to go swimming
17:16in the underground ocean.
17:17They might be home
17:18to some bizarre creatures
17:20who want to feast on…
17:22Well,
17:22we'll come back to that.
17:24Maybe.
17:25As you can see,
17:26we've created
17:27sprawling cities
17:28and thriving communities,
17:29powered by the planet's
17:31geothermal energy.
17:32We also created
17:33a bunch of
17:34artificial light sources
17:35that keep things bright
17:37throughout the dark,
17:38chilly nights.
17:39Of course,
17:39we still have some problems
17:41with navigation
17:41and timekeeping,
17:42but things aren't
17:44as dull as they used to be,
17:45are they?
17:46Overall,
17:47living on a rogue planet
17:48would definitely
17:49have its challenges,
17:50but it could also
17:51be a pretty exciting way
17:53to experience the universe.
17:55And who knows?
17:56Maybe someday
17:57we'll find such a planet
17:58and actually turn it
18:00into a bustling
18:01intergalactic metropolis
18:02someday.
18:03But until then,
18:04let's enjoy
18:05and tidy up
18:06our dear Earth.
18:08Have you ever thought
18:10about Earth itself
18:11as an intelligent,
18:12well,
18:13not creature,
18:14but maybe an entity?
18:16Like,
18:17it has a mind
18:18and some survival instincts
18:19of its own.
18:20When said like this,
18:22it sounds like
18:23you're about to watch
18:23a fantasy movie
18:24where the planet
18:25we walk and live
18:26our daily lives on
18:27will suddenly wake up,
18:29realize it doesn't
18:30like us that much
18:31after all,
18:32and just go crazy.
18:33Hope not.
18:35But we're not
18:36actually talking
18:37about such scenarios.
18:38More of the idea
18:39that the collective
18:40activity of life
18:41like microbes
18:42and plants
18:43can change a planet
18:44and give it
18:45a life of its own.
18:46It's like the planet
18:47has a green mind.
18:50The metaphor
18:51of Earth
18:52as a living planet
18:53makes sense.
18:54Creatures across the globe
18:56crawl,
18:56swim,
18:57walk,
18:57and fly
18:58through the uppermost layers
19:00of our land,
19:01ocean,
19:01and sky.
19:02Plants cover
19:03much of our world.
19:04Plus,
19:05there are viruses
19:05and bacteria
19:06in the water,
19:07soil,
19:08and even atmosphere.
19:11Now,
19:12imagine all the living
19:13things on Earth
19:14like plants,
19:15animals,
19:15and microbes
19:16as a giant team
19:17working together.
19:18They have different jobs,
19:20but they all do their thing
19:21to make the planet
19:22a better place to live.
19:24For example,
19:25plants make oxygen
19:26that we breathe,
19:27and animals help
19:28pollinate flowers.
19:30Together,
19:30they form the biosphere,
19:32which is like the Earth's
19:34team of life.
19:37That's where the idea
19:38of planetary intelligence
19:40comes in.
19:41Just like individuals
19:42and groups
19:43can be intelligent,
19:44so can an entire planet.
19:46Researchers believe
19:47we should measure
19:48the planet's intelligence
19:49by its ability
19:50to keep itself
19:51going forever.
19:52And just like how humans
19:53need to work together
19:54to survive,
19:55a planet's
19:56collective intelligence
19:57is measured
19:58by the capacity
19:59of all the life on it
20:00to work together
20:01towards this same goal.
20:03It's like the planet's
20:04planet is a complex system
20:06that knows how
20:07to take care of itself.
20:08Like forests,
20:10they can share nutrients
20:11through their secret
20:12underground networks
20:13of fungi.
20:14This helps all the trees
20:15stay healthy.
20:16We can obviously learn
20:18a lot from forests.
20:20If we jump
20:21into the fantasy universe
20:22while looking for
20:23intelligent,
20:24conscious planets,
20:25we'd definitely choose
20:26Mogo from Green Lantern.
20:28It's a specific
20:29planetary entity
20:30that can do things
20:31like changing its weather
20:33and altering gravity,
20:34plant growth,
20:35or some other
20:36surface conditions.
20:37Or how about
20:39the stunning Pandora
20:40from Avatar?
20:41Do you remember
20:42the fascinating scenes
20:43of flora and fauna there
20:45with organs
20:46that might remind you
20:47of tentacles?
20:48They enable creatures
20:49to interlink
20:50with each other
20:51on a neural level.
20:52It's like the entire planet
20:54is like one giant brain
20:56with many smaller trees,
20:58creatures,
20:58and its other pieces
20:59as its cells.
21:02We're far from that,
21:04but it's still nice
21:05to imagine.
21:06At the moment,
21:07our civilization
21:08is in the stage
21:09scientists named
21:10an immature technosphere.
21:12That means we're still
21:14too focused
21:14on using technology
21:15that doesn't always
21:17do good for our planet.
21:18We don't have
21:19a planetary intelligence
21:21or a collective understanding
21:22of what needs to be done
21:24to do better
21:24for our planet.
21:26Instead,
21:26we're all just
21:27doing our own thing.
21:29I mean,
21:30we're not
21:31at the worst stage.
21:32Researchers have come up
21:34with four stages
21:35of Earth's past
21:35and future
21:36to explain
21:37how planetary intelligence
21:39could impact
21:40the long-term future
21:41of humanity.
21:42The first stage
21:43is what we call
21:44the immature biosphere.
21:46It's when life
21:47first started on Earth
21:48billions of years ago.
21:50Only microbes
21:51were there
21:51on the bare land
21:52without any vegetation.
21:54There wasn't
21:54any global feedback,
21:55which means
21:56these microbes
21:57couldn't yet
21:58affect Earth,
21:59its atmosphere,
22:00or other systems
22:01in any way.
22:02The second stage
22:04is the mature biosphere,
22:06which was 2.5 billion
22:07to 540 million years ago,
22:10when stable continents formed
22:11and the biosphere
22:13started to have
22:13a strong influence
22:14on the Earth.
22:16The third stage,
22:18known as immature technosphere,
22:20is where we are now,
22:21with interlinked systems
22:23of communication,
22:24technology,
22:25transportation,
22:26electricity,
22:26and computers
22:27that draw resources
22:29from Earth's systems
22:30and affect the biosphere.
22:32The fourth stage,
22:34also known as
22:34the mature technosphere,
22:36is where Earth
22:37should aim to be
22:38in the future.
22:39It means technology
22:41will benefit
22:41the entire planet.
22:42We'll use sustainable
22:44forms of energy,
22:45like solar power.
22:46Planetary intelligence
22:48is the sign
22:48of a mature planet,
22:50and researchers
22:51are trying to figure out
22:52how we can move
22:53towards it.
22:56So,
22:56things we do
22:57on an individual level
22:58do matter.
23:00The collective activity
23:01of life,
23:02like microbes
23:03or plants,
23:03can change a planet
23:05and make it more
23:06than just a lifeless rock
23:07floating in space.
23:09Through the biosphere,
23:11our home planet
23:12kind of figured out
23:13how to host life
23:14by itself
23:15billions of years ago,
23:16and it's still going.
23:17Now we need to figure out
23:19how to have a similar
23:20kind of self-maintaining system,
23:22but this time
23:23with the technosphere.
23:25It's hard to imagine
23:27planets could generally
23:28become sentient,
23:29like Pandora,
23:30or some other
23:31imaginary conscious world
23:32out there.
23:33There are a few reasons
23:34for that.
23:35First,
23:36planets form
23:37based on how
23:38different materials,
23:39like rocks,
23:40gases,
23:40and liquids,
23:41gather around a new star.
23:43It's like you have
23:44a big family gathering,
23:45where everyone brings
23:46different ingredients
23:47to make a delicious dish.
23:49And just like
23:50how these ingredients
23:51won't suddenly turn
23:52into a living being,
23:53the materials
23:54that make up a planet
23:55won't just turn
23:57into self-aware creatures.
23:58On Earth,
23:59after billions of years
24:01of complex chemical reactions,
24:03some molecules
24:04started to replicate
24:05themselves
24:05and carry information.
24:07That's how life
24:08on our planet began.
24:09And Earth
24:10is the only such example
24:12we have.
24:13Here's the second reason.
24:15Imagine you have
24:16a big garden
24:17where you plant
24:18a lot of mushrooms
24:18or bacteria,
24:20hoping they'll become
24:21really smart
24:21and help you
24:22take care of the garden.
24:24But mushrooms
24:25and bacteria
24:25don't have brains
24:27like we do.
24:28Eh,
24:29it's not like
24:29they need it anyway.
24:31Having a big brain
24:33is really expensive
24:34for animals, too.
24:35It takes a lot of energy
24:36to keep it running.
24:38So,
24:38animals only become
24:39as smart as they need to be
24:41to survive
24:41and thrive
24:42in their environment.
24:43Dogs and cats
24:44are pretty smart
24:45because they need
24:46to be able
24:47to avoid danger
24:48and find food.
24:49They don't need
24:50human kind of intelligence
24:51for things like
24:52building houses,
24:53creating art,
24:54or inventing
24:55new technologies.
24:56So,
24:57it would be hard
24:58to bring all living beings
24:59and plants
25:00to the same level
25:01of intelligence.
25:03The third reason
25:04why it would be difficult
25:05for a planet
25:05to become sentient
25:06is the main rule
25:08of the animal kingdom.
25:09Life is all about
25:11survival of the fittest.
25:12Every creature
25:13is competing
25:14for resources
25:14like water,
25:16food,
25:16and space.
25:17But not only
25:18do different species
25:19compete against each other,
25:20but individuals
25:21within the same species
25:22also fight.
25:24Just think of how
25:25fiddler crabs
25:26fight for territory
25:26on the beach,
25:27or how wolf packs
25:29fight over prey,
25:30or me
25:31when I see an empty spot
25:33on a crowded beach.
25:34This kind of competition
25:35is not a good base
25:37for global cooperation.
25:40There are a couple
25:41of exceptions
25:42to this rule.
25:43For example,
25:44ants.
25:45They may not be
25:46the brightest creatures
25:47on the planet,
25:47but when they come together
25:49in colonies,
25:50they can achieve
25:50amazing things,
25:52like gathering food
25:53that's way bigger
25:54than them,
25:55building nests,
25:56raising young,
25:57and even farming.
25:58In fact,
25:59they act like
25:59a superorganism
26:01called a hive mind,
26:02where every ant
26:03works together
26:04towards a common goal.
26:07Insects like bees
26:08and ants
26:08are very altruistic
26:10and work together
26:11to ensure
26:11their queen reproduces.
26:13If one large
26:15ant colony
26:15took over
26:16our whole planet,
26:17it could act
26:18as a single mind
26:19and work towards
26:20the colony's
26:21and planet's interests
26:22until they run
26:23out of resources.
26:24But in reality,
26:26it's hard to imagine
26:27any organism,
26:28even a superorganism,
26:29could reach such a level
26:31of self-awareness
26:32and consciousness.
26:38When it comes
26:39to communication,
26:41ants use pheromones
26:42and humans
26:43use nerves.
26:44Both of these methods
26:45work well
26:46for small organisms,
26:47but when it comes
26:48to a giant
26:49planet-sized entity,
26:50it would be hard
26:51to make such communication
26:52fast and efficient.
26:54So,
26:54communication
26:55within a planet-sized entity
26:57would be much slower
26:58than what we have
26:59in our homes,
27:00like our computers
27:01or smartphones.
27:02Oh well,
27:03we'll just continue
27:04dreaming about Pandora.
