At the coldest, most isolated place on Earth, researchers have uncovered something that doesn’t fit any known category of human technology. Buried deep beneath Antarctic ice, the object appears manufactured — but not by any civilization we recognize. What it is, how long it’s been there, and who made it could challenge everything we think we know about our planet.

00:00A vast expanse of white snow, freezing winds, lifeless landscapes, and weird, eerie signals seemingly coming from within Earth.
00:10These radio pulses occur in Antarctica, and no one can figure out what they are and where they're coming from.
00:18You see, scientists are running an experiment called ANITA, short for Antarctica Impulsive Transient Antenna.
00:25Basically, it's a bunch of detectors strapped to giant balloons and floating way up above the South Pole.
00:31Their job is to detect extremely high-energy neutrinos.
00:36How do they spot them?
00:38Right at the moment when neutrinos come into contact with ice and produce an intense, short burst of radio waves.
00:46Now, neutrinos are these tiny, almost massless particles that don't have an electric charge.
00:52They're everywhere, and billions of them are flying through you every second, even while you're watching this video.
01:00Neutrinos come from all over the place.
01:03From the Sun, exploding stars, deep space, even from under your feet.
01:08The Sun pumps them out non-stop as it fuses hydrogen into helium.
01:13Stars that are going off blast out huge bursts of neutrinos during supernova explosions.
01:19When high-energy cosmic rays hit our atmosphere, they make new neutrinos that rain down on us, too.
01:26And some even come from radioactive stuff decaying inside Earth.
01:31The oldest neutrinos have been flying through the universe since the Big Bang.
01:36But they're practically invisible, because they almost never react with anything.
01:42That's why scientists use unbelievable experiments like ANITA to try and catch even a few of them.
01:49But let's get back to that fateful day when everything changed.
01:54Normally, the radio signals produced by neutrinos bounce off the ice and fly upward.
02:00That's where ANITA can catch them.
02:03This is the whole point of the experiment.
02:05To study neutrinos and learn more about distant cosmic events, like supernovas or whatever's happening light-years away.
02:13But then something really weird happened.
02:16The detectors picked up radio waves that weren't bouncing off the ice at all.
02:20They looked like they were coming from below the horizon.
02:23From under the ice.
02:24Now, this shouldn't even be possible.
02:28According to everything we know about physics, signals can't just travel upward through solid rock and ice.
02:35One of the researchers, Stephanie Wiesel from Penn State, also said that those radio waves were coming in at super
02:42-steep angles, like 30 degrees below the surface.
02:46The only way that could happen is if the signal had passed through thousands of miles of solid rock before
02:52hitting the detector.
02:53But if that were true, the rock would have completely absorbed it.
02:57So something just didn't add up.
02:59The team ran all the numbers and still got no clear answer.
03:03But for them, it was an interesting problem, since they didn't actually know what those anomalies were.
03:10What they did know was that they were probably not neutrinos.
03:15That's because if the team does detect a neutrino, that means it's traveled an insane distance without bumping into anything,
03:22possibly all the way from the edge of the observable universe.
03:27So, whatever Anita has picked up, it's not behaving like anything scientists have seen before.
03:32It might mean there's some totally new type of particle out there, or maybe something else is going on that
03:37we just don't understand yet.
03:39They published the findings in physical review letters, but the mystery remains unsolved.
03:45No one really knows what's going on under that Antarctic ice.
03:48Just that something out there isn't playing by the rules.
03:52Now, if scientists actually manage to detect and trace where those crazy fast particles come from, they can learn tons
03:59of stuff about the universe.
04:01Way more than even the biggest, most expensive telescopes allow us to see.
04:06You see, neutrinos basically zip through space almost at the speed of light, barely bumping into anything.
04:13It means they can carry untouched data about events that happened millions or even billions of light years away.
04:19That's why WISL and a bunch of other researchers around the world have been building these insanely sensitive detectors to
04:27catch neutrino signals.
04:29Even the tiniest ones are super important.
04:31Because in this field, one tiny blip of data can hold a treasure chest of information.
04:38So, researchers have been designing setups in both Antarctica and South America to catch these rare particles.
04:46ANITA is one of those detectors, and Antarctica's the perfect spot for it.
04:51There's hardly any radio noise, there are no cities, no traffic, and no random interference.
04:57The setup is actually pretty cool.
05:00They attach a cluster of radio antennas to a giant balloon, send it a few dozen miles up into the
05:06sky,
05:07and make it float over the endless stretches of white ice.
05:10From up there, it points downward, listening for faint radio signals coming from deep inside the ice.
05:16When one of those super-rare neutrinos, specifically a tau neutrino, hits the ice,
05:22it creates another particle called a tau lepton.
05:25That lepton then shoots out of the ice and starts breaking down, losing energy and turning into smaller bits.
05:31That decay process gives off what's called an air shower,
05:34kind of like a spray of invisible sparks flying through the air.
05:38If we could actually see those air showers with our eyes,
05:42they'd look like someone waving a sparkler through the dark,
05:45bright streaks trailing behind as it moves.
05:49Studying the direction and pattern of these signals,
05:52the ones from the ice, ice showers,
05:55and the ones in the air, air showers.
05:58Scientists can figure out where the original particle came from.
06:02Usually it's super precise,
06:04kind of like bouncing a ball off the ground.
06:06You can predict where it'll go.
06:09But these weird new signals don't bounce the way they're supposed to.
06:14The angles are all wrong way steeper than anything the models can explain.
06:19So, the team dug deeper.
06:21First, they looked at all the data from ANITA's multiple balloon flights.
06:25Then they compared it against tons of computer simulations of cosmic rays and neutrinos
06:30and filtered out all the usual background noise.
06:33They even cross-checked their results with other experiments like the ice cube detector,
06:38which is also located in Antarctica,
06:41and the Pierre Auger Observatory in Argentina.
06:44They wanted to see if anyone else had picked up similar upward-going air showers.
06:49And guess what?
06:51Things got even weirder.
06:52They found...
06:54nothing.
06:55No other detectors had picked up anything that could explain what ANITA had seen.
06:59That's why the researchers ended up calling the whole situation anomalous.
07:03It basically means,
07:05yeah, we have no idea what this is,
07:07but it sure isn't behaving like a neutrino.
07:10Whistle explained that the signals just didn't fit into the usual picture
07:13of how particles were supposed to act.
07:15Some people have floated ideas,
07:17like maybe it's some new kind of physics,
07:20or a hint of dark matter.
07:22Dark matter is basically that invisible stuff
07:25that keeps the universe from falling apart.
07:27It's everywhere.
07:28We just can't see it.
07:30Scientists have been trying to figure out what it actually is for almost a century,
07:34and it's still one of the biggest mysteries out there.
07:38Everything we can see,
07:39like stars, planets, people, dogs,
07:42makes up only about 5% of the universe,
07:44and dark matter makes up around 27%.
07:47The rest is something even stranger,
07:50called dark energy.
07:52Scientists think dark matter is what gives galaxies their shape,
07:56and holds everything together like cosmic glue.
07:59Without it, the universe would look totally different.
08:02It would be totally amazing to find out that this theory is true.
08:06But since Ice Cube and Augur haven't caught the same thing,
08:09that really limits the possibilities.
08:12Penn State has been in the neutrino-detecting game for almost a decade now,
08:17building detectors and analyzing all kinds of cosmic signals.
08:20And the team is already working on their next big project,
08:24a brand new detector called Pueo.
08:26It's going to be bigger, more sensitive,
08:28and way better at spotting those elusive neutrino signals.
08:32For now, this remains just one of those long-running cosmic mysteries
08:36that keep scientists awake at night.
08:38But the team is optimistic.
08:40When Pueo goes up, it'll have better sensors,
08:43which means if there really are more of these anomalies out there,
08:47this time, they'll catch them.
08:49And maybe then, we'll finally figure out what's behind them.
08:55Welcome to one of the most mysterious and unexplored places on Earth.
09:00Um, but what's so special about that?
09:03It's just some icy peaks and the endless snowy expanse of Antarctica.
09:07Yeah, that's right.
09:09But there's still a planetary scale mystery here.
09:12No matter how hard you try, you won't see a hidden mountain range,
09:16giant, unexplored land where no human has ever set foot.
09:20And it lies under another layer of mountains.
09:24It's like a nesting doll, but the size of a continent.
09:28These mountains hide Antarctica secrets.
09:31And these secrets can tell us something awesome
09:34about the ancient history of our planet.
09:38This gigantic, unexplored territory in Antarctica
09:41is called the Gambritsev Subglacial Mountains.
09:44And the layer of ice above keeps this place untouched by nature and people.
09:50It's like a land inside another land.
09:53And it hides more than just mountains.
09:55There are valleys, hills, and plains.
09:58The whole area is similar to the European Alps.
10:01But unfortunately, we can't enjoy the view.
10:05Those mountains were first discovered in 1958 using seismological instruments.
10:10More than half a century has passed since then.
10:14And this place still remains one of the most poorly studied tectonic objects on Earth.
10:19Why?
10:20Because it's ice.
10:21A lot of ice.
10:24Who knows?
10:25Maybe there are some unknown ancient artifacts lying there.
10:28What if they're hiding a secret city or spaceships?
10:31It's unlikely, of course, but it would still be interesting to look there.
10:35Think about it.
10:36Hundreds or even thousands of miles of land that have remained unchanged for hundreds of millions of years.
10:44Even if no new species of animals or remains of an ancient civilization are there, this place still has a
10:51history.
10:52The history of the formation of continents on our planet.
10:56And scientists have already figured out some of this story.
11:01The mountains buried in Antarctica were originally like ordinary mountains.
11:06But as a result of a planetary scale event, they just...
11:09Wait a minute.
11:10Have you ever wondered how mountain ranges are formed?
11:13We see them in real life.
11:15In movies.
11:16In photos on the internet.
11:18We climb them.
11:19But how did they appear?
11:21Mountains have not always existed on the planet in this form.
11:24They appeared as a result of a large-scale collision of tectonic plates.
11:28Two giant solid chunks of ground are moving toward each other, then crash, and boom!
11:35Millions of tons of the Earth's crust pile on top of each other, mix, and form ledges and gorges.
11:43And all this can last for millions of years.
11:47Yes, it's a disaster, but it's very slow.
11:51Some tectonic plates are still colliding.
11:53For example, the Himalayas continue to grow because the Indian and Eurasian plates are still ramming into each other.
12:00And this process began about 50 million years ago.
12:05The Gambertsev Mountains under ice experienced a similar event, only much earlier.
12:10An article in the journal Earth and Planetary Science Letters says that they appeared during the formation of the supercontinent
12:17Gondwana.
12:19Two giant pieces of land were separated by a boundless ocean.
12:24But then, about 700 million years ago, they collided and formed Gondwana.
12:30This supercontinent included the territories of modern Africa, South America, Australia, India, and Antarctica.
12:38The giant pieces crashed into each other and released a stream of hot, partially molten rock.
12:45This mess grew bigger and bigger, forming mountains.
12:48The temperature of those mountains grew, their mass increased, and at some point, Gondwana became unstable.
12:55The supercontinent began to collapse under its own weight.
13:00The hot rocks below the surface began to flow sideways as a result of a process called gravitational spreading.
13:07Take toothpaste and start squeezing it out of the tube.
13:11Approximately the same thing happened with billions of tons of red hot rock.
13:16Ancient mountains in Antarctica appeared right during this catastrophic event.
13:21You've just watched a visual simulation of global events that took place hundreds of millions of years ago.
13:28It looks cool, but how did scientists figure it out?
13:31How did they see this planetary scale destruction?
13:35If the Gambertsev Mountains under ice is one of the most unexplored places in the world,
13:40then how could people find out its origin?
13:43The answer is simple.
13:45Tiny particles of rock have told us about the changing landscape of the planet.
13:51These are zircons, but scientists also call them time capsules.
13:56This mineral is very handy and resistant to mechanical and chemical influences.
14:01It's difficult to crush, it doesn't get affected by erosion, and it doesn't dissolve in water.
14:07And there's uranium inside it.
14:10This chemical element shows scientists the age of the rock.
14:14The fact is that uranium always decays into lead at the same rate.
14:19Scientists look at the ratio of uranium and lead and determine the age of minerals with great accuracy.
14:26Okay, this sounds a bit complicated.
14:29Here's a simple example.
14:30Imagine that each mountain belt is a clock that starts ticking at the moment of its formation.
14:36That is, after the collision of tectonic plates.
14:39After the rock forms, uranium begins its slow decay.
14:43The more time passes, the more uranium turns into lead.
14:48The rate of this decay is always the same.
14:51This decay can last for billions of years.
14:54The less uranium is in zircons and the more lead, the older the rock is.
14:59And this is how it happens in practice.
15:02Geologists take several rock samples.
15:05In a lab, they crush it to extract crystalline zircons.
15:10Geologists then dissolve the particles in acid to separate uranium from lead.
15:15Then, they use a special device.
15:17A mass spectrometer that accelerates atoms and sorts them by mass.
15:21This is a rather complicated process, but the bottom line is that this device shows scientists the amount of uranium
15:29and lead.
15:30They look at the ratios of these two elements and calculate the age of the rock.
15:36Geologists took zircons from sandstones near the Gambertsev Mountains, studied those particles,
15:42looked at the level of uranium, and calculated the chronology of mountain formation.
15:47Then, they compared the data obtained with the history of our planet and realized that the mountains buried in Antarctica
15:54appeared during the formation of the supercontinent Gondwana.
15:58But how did they find out that the supercontinent included Australia, India, and Africa?
16:04Zirconia from those Antarctic rocks turned out to be very similar to zirconium from those countries.
16:10That is, a long time ago, these three continents were together.
16:15So, the Gambertsev Mountains began to grow about 650 million years ago.
16:21About 580 million years ago, they reached the height of the Himalayas.
16:25And 80 million years later, they experienced the melting of the Earth's crust.
16:30And while most of the mountain ranges on the planet were changing and collapsing,
16:35the Gambertsev Mountains under ice remained untouched.
16:40Water, soil, wind, earthquakes, gravity, and other natural forces destroy mountain belts.
16:47This process is called erosion.
16:49But mountains buried in Antarctica haven't experienced anything like this.
16:53The cold temperature and the ice sheet around them kept this range unchanged.
16:58It's one of the best-preserved ancient mountain belts on the planet.
17:01Okay, but why do we need to explore these mountains?
17:05What difference does it make that the supercontinent Gondwana collapsed in the past?
17:10It's possible that plants, frozen bodies of insects, or ancient bacteria have remained preserved under thick layers of ice.
17:18What about ancient animals?
17:20Many species could have lived on Gondwana.
17:23Studying ancient mountains in Antarctica can show us what the planet looked like about a half a billion years ago.
17:30When Antarctica was a green continent, what lived on it?
17:33What happened to this life?
17:35Is it possible to revive those ancient creatures after so many years?
17:40If scientists were able to calculate the date of the supercontinent's appearance using tiny particles,
17:45then imagine what they could find after examining this hidden mountain range.
17:50It all sounds very interesting.
17:53But there's one problem.
17:55To take a small piece of this unknown world, you need to drill through a lot of ice.
18:00You need to deliver heavy equipment to one of the most inaccessible continents in the world,
18:05build stations, obtain an energy source, and conduct large-scale research.
18:10It sounds incredibly expensive, so this hidden territory will probably remain a mystery for a long time.
18:17Let's just hope that some billionaire will want to find out Antarctica's secrets and arrange a large-scale expedition there.
18:25In 2020, strange signals from deep beneath Antarctica sent shockwaves through the news.
18:33Within days, headlines exploded.
18:36NASA had found a parallel universe where time runs in reverse.
18:41But what really happened?
18:43And what did scientists actually detect?
18:46Well, this story is a case of madness, misunderstood experiments, and the human need to believe in mystery.
18:56Even today, every few months, someone reposts a headline screaming that NASA found a parallel universe in Antarctica.
19:04A universe where time flows backwards, and people believe it.
19:08But no, NASA didn't find a mirror world under the South Pole, or some sort of a backwards reality where
19:15people age in reverse or speak in rewound sentences.
19:19They did find something curious, though.
19:22Here's what actually went down.
19:25Scientists were flying a strange-looking instrument over Antarctica called ANITA, short for Antarctic Impulsive Transient Antenna.
19:34ANITA is a machine that floats over Antarctica.
19:38Basically, a giant balloon with antennas.
19:41It listens for tiny space particles called neutrinos.
19:46Neutrinos are super small and ghost-like.
19:49They have almost no weight and go through stuff like it's not even there.
19:53Even entire planets.
19:56Usually, these neutrinos come from space and reign on Earth from above.
20:02Most neutrinos, the common low-energy ones, just fly right through the Earth like it's air.
20:08They're like tiny bugs flying through a chain-link fence.
20:12There are some very high-energy neutrinos, though.
20:16They're super rare, and they interact a bit more often with matter.
20:20And they can get blocked.
20:23If high-energy neutrinos hit something dense enough, like the rock and metal inside Earth, they might finally bump into
20:31a particle and get absorbed.
20:33That's more like fast tennis balls that hit the fence once in a while.
20:38Low-energy neutrinos, which are everywhere and pretty harmless, are pretty undetectable.
20:44But these high-energy guys are exactly what ANITA can detect.
20:49When they slam into ice, they send some radio waves that are easy to listen to.
20:54This faint radio signal is called the Ascarian effect.
20:59And yep, that's exactly why ANITA is flying over Antarctica.
21:03That's because the ice is pure, dry, and quiet.
21:08It's perfect for catching those rare signals.
21:12So, what did ANITA detect?
21:15It detected something rising up from below the ice, like a high-energy neutrino coming from the Earth.
21:22What?
21:24Okay, let's think logically.
21:26Maybe it started somewhere in the north, traveled all the way through the Earth, and popped out the other side.
21:33Still, that's super weird.
21:35That's not supposed to happen.
21:37Neutrinos with that much energy should have been stopped inside the planet.
21:42Like we said, get absorbed.
21:45So, scientists caught a little bit of a brain bug.
21:48That shouldn't be possible with our current physics.
21:51Unless something we don't understand is going on.
21:55And when you're faced with something bizarre, you explore all options.
21:59Even the wildest ones.
22:02The nightmare began.
22:04A group of researchers published a paper suggesting that this strange signal might make sense in a CPT symmetric universe.
22:13CPT stands for charge, parity, and time.
22:17These are basically three ways to flip the universe.
22:22Charge means swap all particles to their opposites.
22:26For example, swap electrons.
22:29The guys with the negative charge with positrons.
22:32They're antimatter twins with the positive charge.
22:36Parity means mirror the universe.
22:38Literally like looking at it through the mirror.
22:41Left becomes right, and right becomes left.
22:45And time, of course, means run time backward, like rewinding a video.
22:51Now, there's a big rule in physics called CPT symmetry.
22:55It says that if you change all three of those things at once, the laws of physics should still work
23:01the same.
23:02This is kind of insane.
23:04But if you took the entire universe and swapped matter with antimatter, mirrored it, and reversed time, it would still
23:12follow the same physics.
23:14Why is that?
23:16Well, in our universe, an electron bumps into a positron, and they annihilate into photons.
23:23Cool!
23:24Now take that, mirror everything, and what do you get?
23:28Well, photons spontaneously turn into a positron and an electron, but mirrored and reversed.
23:36It's still the same physics, even if it's backwards.
23:39The equations still check out, so nature thinks this is valid.
23:45So here came the crazy part.
23:47Some physicists thought, what if the Big Bang created two universes?
23:53One is ours, made of normal matter, going forward in time.
23:57The other is a mirror twin, made of antimatter, going backward in time from our perspective.
24:04This doesn't mean that someone in the other universe feels time going backward.
24:09To them, time flows forward, just like it does for us.
24:12But from our point of view, they're moving from our future toward our past.
24:18And vice versa.
24:19To them, we're weirdos who move backwards.
24:22And if both universes are exact CPT mirror images of each other, that would mean
24:28Same physics, same rules, just symmetrical.
24:33Same rules, just symmetrical.
24:36This isn't some crazy sci-fi theory, even if it sounds like it.
24:40It helps explain weird physics mysteries.
24:43For example, why there's so much matter in our universe, but not much antimatter,
24:48even though they were supposed to be created in equal proportions.
24:53Or why the universe is so symmetrical and balanced in some strange ways.
25:00So, coming back to the neutrinos, some scientists suggested that maybe those upward-flying particles
25:06could be coming from that CPT mirror universe.
25:10Poking through into ours.
25:12Like a crack between two symmetrical realities.
25:16And if you look at it like that, this is quite a wild take.
25:21It's speculative.
25:22It's not proven.
25:23It's more of a cool thought.
25:25But the media immediately blew up.
25:27They ran a piece with the headline that said we found proof of a parallel universe going backwards
25:33in time in Antarctica.
25:35And all the other big tabloids picked it up.
25:38They made it sound like NASA had actually found a parallel universe.
25:43Time travel is real.
25:44Multiverse is confirmed.
25:46Meanwhile, people who worked directly on ANITA immediately caught brain damage.
25:52They tried to jump in to say that's not what happened at all.
25:55They explained that the signals were unusual, yes.
25:59But there were plenty of normal explanations that didn't require rewriting the laws of physics.
26:05It could even be just an experimental error.
26:09Maybe an unusual particle behavior or gaps in how we model neutrino interactions.
26:14Of course, no one listens to experts about what experts discovered.
26:20And once an idea like that hits social media, it becomes nearly impossible to put back in the box.
26:27But that also doesn't mean that the multiverse definitely isn't real.
26:32Far from it.
26:33Physicists are still exploring the concept and assume that some of those potential universes,
26:38if they exist, could have different laws of physics.
26:43One idea, called the many-worlds theory, comes from quantum physics.
26:49It says that every time something can happen in more than one way,
26:53like a particle moving or a decision being made,
26:57all those possibilities actually happen, but in separate universes.
27:02So, there could be endless versions of reality, each slightly different, branching off from every event.
27:10Maybe in one universe, dinosaurs never went extinct.
27:14Maybe in another, you never sent that embarrassing text.
27:18Another theory is called the Bubble Universe Theory.
27:21After the Big Bang, the universe expanded incredibly fast in a process called inflation.
27:30Some scientists think that inflation never fully stopped and is still happening in some regions.
27:35That would mean new bubble universes are constantly forming,
27:40each with its own version of physics.
27:42Our universe would just be one bubble in a giant cosmic sea of others.
27:50The third idea is about shadow matter.
27:53Dark matter is invisible, but its gravity affects the universe.
27:57Some scientists think it could be made of particles similar to the ones that make up regular matter,
28:03but they're just hidden from us.
28:05This mirror, or shadow matter, could form entire invisible galaxies, and even life,
28:12all existing right alongside us.
28:14Maybe we just can't detect it in any way, except through gravity, for now.
28:20But in physics, all of those are just theories, mathematical possibilities.
28:27We have no direct evidence that it's real.
28:29If we ever find one, though, let's now hope it won't be the Boy Who Cried Wolves scenario.
