NARRATOR: Hidden portals

to alternate realms and timelines,

rare glimpses of rifts in the fabric of space-time,

and extraordinary encounters

with time travelers from the future.

For nearly two decades,

Ancient Aliens has traveled the globe,

exploring towering megalithic structures,

mysterious artifacts,

and stories of otherworldly beings

in a quest for evidence that might reveal the truth

of our extraterrestrial origins.

It's fascinating to contemplate that

we're destined not just to become space travelers

but time travelers, too.

NARRATOR: Now we take a look back

through the Ancient Aliens archives

to the show's very origins

to examine the evidence that we are not alone.

We have never been alone.

♪ ♪

In most of the Western world, we conceive of time

as a straight line of past, present and future,

but in many cultures they think of time as a plane

in which you can move backwards and forwards.

DAVID CHILDRESS: Yeah, we have this in many

Eastern traditions,

and the Mayans believed in this, too.

And they described otherworldly beings

coming from different points in the universe

and from different points in time.

GIORGIO A. TSOUKALOS: Well, Albert Einstein

proved theoretically that time travel is possible.

We talked about this

in a 2012 episode of Ancient Aliens

called "The Time Travelers."

NARRATOR: Bern, Switzerland, September 26, 1905.

Albert Einstein publishes

his special theory on relativity.

According to his astonishing scientific breakthrough,

space and time are one.

RONALD L. MALLETT: In the old theory of Newton,

space was a rigid container

and time was an absolute flow.

In Einstein's theory, this was revolutionized.

Space now became a flexible medium,

and time now could be altered.

MICHAEL DENNIN: Einstein realized that if you move faster,

the ticks on your clock actually change.

Prior to Einstein, no one understood that

or would even have expected that

because it only happens

when you get very, very close to the speed of light.

SARA SEAGER: There is a way within the laws of physics

to travel long distances and still be alive.

And that actually is related to special relativity

and the idea that

if you can travel very, very close

to the speed of light, time will slow down for you.

And in this sense, if you could travel

very near the speed of light, only a day or two would pass

instead of the whole four years.

NARRATOR: January 30, 1933,

Berlin, Germany.

Adolf Hitler and his Nazi Party take power,

and Albert Einstein flees to the United States.

Fearing Hitler's rise to power, he warns the U.S. and the world

of terrible dangers posed to humanity,

especially if Nazis were to acquire advanced technology.

But by revealing to the world his breakthrough theories,

might Einstein have accidentally helped the Nazis

build a time machine?

Southwest Poland, the Owl Mountains.

Here, concealed under rolling hills,

were seven underground complexes

built for a top secret Nazi program

called Die Glocke.

Some researchers believe

it was in these covert facilities,

between 1943 and 1945,

that Third Reich scientists

carried out clandestine experiments

in an effort to win World War II.

JIM MARRS: They were developing lots of exotic things.

They were in charge of the V-1, the V-2 rocket programs.

But then I think the culmination of their experimentation

was with Die Glocke, or "The Bell,"

and they called it that because it was bell-shaped.

MIKE BARA: And what this appeared to be was some sort of device

that had very, very powerful,

rapidly rotating, energetic magnetic fields.

And there are thoughts that this basically was a time machine.

That the idea was that you would be able

to move back and forth in time,

change history,

change certain events, and create a new timeline

and a new reality.

NARRATOR: The existence of the mysterious bell-shaped device,

measuring nine feet wide and 12 feet tall,

was first exposed by the high-ranking Nazi general

Jakob Sporrenberg while being interrogated

by Polish authorities after the war.

But when the Allies eventually captured

the German research center, neither the Nazi Bell

nor its project commander Hans Kammler

could be found.

BARA: Hans Kammler was in charge

of all the super-secret Nazi technology,

and this guy just disappears after the war.

In fact, there are four official versions of his death.

So nobody really knows how he died, when he died,

if he died, where he went, or what happened.

NARRATOR: Is it possible that the German military

was experimenting with time travel technology?

And if so, might the Nazi Bell

have actually traveled to the future?

December 9, 1965.

Thousands witness a brilliant fireball

flash across the sky

before crashing in Kecksburg, Pennsylvania,

30 miles southeast of Pittsburgh.

MARRS: The military was immediately on the scene,

grabbed everything up, and then said nothing happened.

The thing that intrigues me about the Kecksburg crash

is the description of the object.

Unlike most of the flying saucers

you hear about, this one was bulbous.

It has been described like an acorn,

or what I could see is kind of something

that resembled the Nazi Bell.

NARRATOR: Might the object that crashed at Kecksburg

have been the long-lost Nazi Bell

that disappeared 20 years earlier?

And is it possible that German scientists

had discovered a way to transport humans

from one time and place to another,

as some researchers believe?

If so, did they use Einstein's theories

to create their own time machine?

Or might their inspiration have been perhaps more divine?

Tibet, May 1938.

While on an expedition through the northeast region

of the Himalayan mountains,

Nazi officials searching for the origins

of the Aryan, or master race,

instead discover the Buddhist teachings

known as the Kalachakra.

In the Buddhist tradition, there is the notion of samsara,

or the wheel of time.

In the Kalachakra initiation,

the teaching is to understand time,

particularly biological time...

...calendar time, and astrological time,

and how those things actually influence you.

(monks chanting)

PHILIP COPPENS: And so, what the discipline

of Kalachakra is telling us is that whereas

we seem to see time as linear, this is not the case,

that time is somehow cyclical

and that we can somehow master this and control time.

Throughout the Buddhist world,

the Buddhists build, uh, what they call stupas.

And they look very much like the Nazi Bell.

COPPENS: The stupas-- it is sensed that we can use this shape

to somehow connect with the gods.

Now, when we put the practice of Kalachakra on this,

what we are talking about is somehow a practice

of transcending time.

BARHAM: The Kalachakra teaching

gives individuals actual practices and techniques

to be able to step outside of time

and to be able to move in time.

So it's entirely possible

that the Nazis were looking for secrets

on how to travel in time.

NARRATOR: Is it really possible that the Nazis unlocked

the secrets of time travel

during their expedition in Tibet?

And if so, might the early teachings of the Kalachakra

be evidence that ancient Tibetan Buddhist monks

had knowledge of time travel thousands of years ago,

as some ancient astronaut theorists believe?

Perhaps the answer can be found in the legends and rituals

of an ancient civilization in New Mexico.

One place that's always fascinated me

is Chaco Canyon

in the desert of New Mexico.

And it is built with very precise geometry

and was built by the Anasazi

-over a thousand years ago. -HENRY: Right.

And according to Native American tradition,

this is the place where the Anasazi went to contact

star people who could traverse space and time.

Yeah, I mean, I visited Chaco Canyon in 2012,

and I saw some of the most amazing petroglyphs

featuring these very strange humanoid figures.

And many Native Americans today claim

that these carvings are representations

of the so-called "star people."

(hawk screeches)

NARRATOR: Chaco Canyon, New Mexico.

In a remote desert region

150 miles northwest of Albuquerque

lie the mysterious ruins of an ancient Pueblo people.

Called the Anasazi,

they thrived from 900 to 1100 AD.

TSOUKALOS: This is the plaza of Pueblo Bonito.

This is a representation of our place in the universe.

You've got the worlds above, the worlds below,

and this right here is our plane of our world.

This is the exact place where time and space began

for the ancestral Puebloans who inhabited this place

hundreds and hundreds of years ago.

NARRATOR: Scholars believe the Anasazi, or "ancient ones,"

built their civilization with advanced knowledge

of engineering, mathematics and astronomy.

SEAN-DAVID MORTON: Somehow, someway, they built a city

that is perfectly circular,

that goes out in perfectly straight lines,

that the structures of the city themselves actually predict

the 5,200-year cycle of the Moon and cycles of the Sun,

all in the geometry.

All in the stone, if you will.

MARSHALL KLARFIELD: These are very elaborate constructions

which required engineering skills beyond

what the local folks had.

And it had to be done by an advanced civilization.

RED STAR: The Anasazi built Chaco Canyon.

And they built it as part of a promise of a way of living.

That they were to uphold the wishes of the Creator.

And so, Chaco Canyon is the delivery of the teachings.

The teachings came from the star people.

NARRATOR: But how did these ancient people

engineer such elaborate structures

without modern machinery?

And just who were the star people

who brought knowledge to the Anasazi?

Ancient astronaut theorists believe the answers can be found

by looking at the ancient rituals

and myths of Chaco Canyon.

According to local legends,

the Anasazi believed in a multidimensional existence

and practiced sacred rituals called crystal stargazing,

ceremonies believed by some to enable time travel.

RED STAR: If you go up into the cliff dwellings of the Anasazi,

there are elaborate star maps up in those caves.

And that's where the crystal stargazing ceremonies

took place,

where they had the ability to traverse space and time.

COPPENS: What we're seeing within this area

are people who basically say that they somehow emerged

out of a different dimension onto this place.

And they say that this for them is a place of emergence.

They say that they interacted

with mysterious creatures.

NARRATOR: Did the Anasazi really believe

in interdimensional time travel,

as some ancient astronaut theorists believe?

If so, might they have left behind

tangible evidence of otherworldly contact?

I'm standing in front of the petroglyphs at Una Vida.

And they're very amazing as you can tell.

With animal life,

but there's also some very weird creatures standing there--

humanoid figures-- and one guy is holding

what, to me, looks like a representation

of a spiral galaxy.

Native Americans were very aware of our place in the universe,

that we were part of a giant spiral galaxy.

RED STAR: The spiral symbol,

the one that you see on the walls,

is a connection between the Anasazi

and the extraterrestrials.

They had contact.

And they either came with them or they either left with them.

We just don't know.

But it's a bridge that existed

between the Anasazi and the star people.

TSOUKALOS: Four very interesting

humanoid petroglyphs have been found,

one of which hovers above the other three humanoids

with antennae sprouting out of its head.

Some have suggested that this is a depiction

of the ancient Ant People

that emerged to essentially jump-start human civilization.

NARRATOR: According to the legends of the Hopi,

a Native American tribe

believed to be the descendants of the Anasazi,

the Ant People saved them

from the first destruction of the universe.

HENRY: The Ant People are described

as very special cosmic visitors,

maybe even star beings, extraterrestrials

who rescued them from this cataclysm

by taking them underground.

What's interesting about this is that in ancient Sumeria,

they tell of beings called the Anunnaki

who also came from the stars.

The Hopi word "anu" means "ant,"

and the word "naki" means "friend."

Is it possible that the Anunnaki

are the ant friends or Ant People

that the Hopi were describing?

NARRATOR: Did the Anunnaki of ancient Sumeria

also appear here in Chaco Canyon thousands of years ago,

as many ancient astronaut theorists believe?

Perhaps the answer can be found

in the local legend of the Wingmakers.

1972.

A group of hikers exploring a system

of hidden caverns in Chaco Canyon

discovered wall paintings and even cuneiform writing

similar to those found on Sumerian artifacts.

After careful analysis,

ancient astronaut theorists suggest that the caverns

were originally inhabited by beings

visiting from the future called the Wingmakers.

CHILDRESS: The Wingmakers were, they claimed,

humans-- and in a sense,

extraterrestrials-- from 300 years in the future.

And they were using Chaco Canyon

as their base for this time zone

where they were coming from the future

into our present time.

RED STAR: My belief is that yes,

the Wingmakers were the culture bearers

bringing us a look at what our future was,

which was mathematics,

it was science, it was art, it was cultivation.

NARRATOR: Might there be truth to the story

of the time-traveling Wingmakers at Chaco Canyon?

And if so, is it possible

the Wingmakers were actually alien visitors?

Ancient astronaut theorists say yes

and suggest the evidence still lies in Chaco Canyon.

TSOUKALOS: This is a kiva.

A kiva was known to be the most sacred of places

where ceremonies took place with the ancestral Puebloans

when they talked about the cosmos--

the universe-- and our place in the universe.

NARRATOR: Mainstream archaeologists believe the kivas

were once covered with timber to make a roof.

But strangely, some Hopi legends

refer to this circular structure as a "cloud house."

What if these cloud houses were nothing else

but biodomes, or biospheres, made of nuts and bolts?

It is interesting that biospheres today

look as if people are living sort of sunk into the ground

with a giant dome over it,

and here we have something very similar.

So the question is, why would anybody do this?

And according to the ancient myths,

they were witness to an incredible event

that had something to do with ancient aliens...

...and to them, it was a divine encounter.

NARRATOR: Is it possible that alien beings inhabited

biospheres in Chaco Canyon,

like those our own scientists envision

for future use on other planets?

And might they have traveled here not in spacecraft

but through an interdimensional space-time portal?

But if so, where did they come from?

Perhaps answers can be found halfway around the world

in the ancient Indian text of the Mahabharata.

NARRATOR: The Mahabharata.

In this sacred Indian text

written in the eighth century BC,

King Raivata is described as traveling

to the heavens to meet with the creator god Brahma.

Only to return to Earth hundreds of years in the future.

Some researchers believe this Hindu tale

may be one of the oldest records

of successful time travel in the ancient past.

CHILDRESS: There's the story of, uh, a king called Raivata,

and he is taken into space to see the gods.

And when he returns to the Earth,

he finds that many ages have gone by

and it's been hundreds of years.

And this is the kind of thing that would happen

to space travelers and in time travel as well.

You think you're gone for only a few days,

but when you return to Earth, you find out

that you've been gone for hundreds of years.

NARRATOR: Like the legend of Chaco Canyon,

similar tales of time travel can be found

all around the ancient world.

In Japan, the legend of Urashima Taro

details a fisherman's visit to the protector god of the sea,

Ryujin, in an underwater palace

for what seemed like only three days.

When he returns to his fishing village,

he finds that it's been 300 years that he's been gone.

And his house is in ruins, everybody he knows is long dead,

no one remembers him or his family.

NARRATOR: And in the Hebrew Bible,

descriptions of the prophet Jeremiah in Jerusalem

are eerily similar to both of these accounts of time travel.

ERICH VON DÄNIKEN: Even in the Bible, the prophet Jeremiah

was sitting together with a few of his friends,

and there was a young boy. His name was Abimelech.

And Jeremiah said to Abimelech,

"Go out of Jerusalem, there is a hill,

and collect some figs for us."

The boy went out and collected the fresh figs.

All of a sudden, Abimelech hears some noise and wind in the airs,

and he'd become unconscious, he had a blackout.

After a time, he wakes up again,

and he saw it was nearly the evening.

So he runs back to the society,

and the city was full of strange soldiers.

And he said, "What's going on here?

Where is Jeremiah and all the others?"

And an old man said, "That was 62 years ago."

It's a time travel story written in the Bible.

NARRATOR: Southern Egypt. Agilkia Island.

Here, just six miles upstream from Aswan

in the Nile River Valley, lies the Temple of Isis.

Built in the fourth century BC,

the temple was a center of worship for the Egyptian goddess

of fertility and nature until the sixth century AD.

Isis became the most important deity

which ancient Egypt ever had.

She was married to her brother Osiris,

and together they really became the popular husband and wife

which everybody wanted to be like.

She is seen as a symbol of life, whereas Osiris is seen

as the deity who rules over the dead.

And so, whether you are alive or whether you're dead,

you can always identify with Isis and Osiris.

NARRATOR: According to ancient Egyptian religious belief,

the goddess Isis was known as the divine mother

and believed to be the soul of the brightest star in the sky,

Sirius.

BARA: To the ancient Egyptians, Osiris was Orion.

That constellation actually was a literal living embodiment

of the great god Osiris.

Sirius was the representation

of his wife, sister and consort Isis.

Together, those two essentially ruled

the skies and the life of the Egyptian people themselves.

CHILDRESS: Many ancient cultures, including the Egyptians,

Chinese, the Greeks, the Japanese,

all had beliefs and legends that

our gods who created us have come from Sirius.

And this star-- extremely important star

to almost all ancient cultures.

This knowledge originally emerged

in ancient Egypt and in Africa with the Dogon tribe...

...who taught that beings of light came from Sirius

and created humankind.

COPPENS: It is clear that so many cultures

possessed information about Sirius,

and they single out Sirius apart from everything else,

and it's got nothing to do with its brightness.

It has to do with the fact that somehow

Sirius is responsible

for sending us emissaries who educate us.

NARRATOR: Could the Sirius star system really be the point of origin

for the gods of ancient man?

Or was it, in fact, the place of origin

for extraterrestrial time travelers,

as ancient astronaut theorists believe?

According to astronomers,

Sirius is approximately 8.5 light-years away from Earth,

an incredibly vast distance.

SETH SHOSTAK: A light-year is about, hmm, six trillion miles,

so it's quite a ways to Sirius.

Our best rockets go about seven miles a second.

So that's pretty fast, but even at that speed,

to get to Sirius would take about 200,000 years.

SEAGER: So far, the farthest humans have traveled is the Moon,

at about 250,000 miles away.

Our next step will be Mars someday.

But even that is a huge, huge stretch for humans.

Six-month trip to Mars

and just being able to survive there without oxygen

and the things we usually have around us is a huge challenge.

The distances are too vast, and our technology is just

nowhere at the level of being able to do that.

We got to the Moon, and that's as far as we got.

That's not to say that another civilization

couldn't have done that. It's just, on Earth,

we just don't have the technology to do that.

NARRATOR: What if interstellar distances were too great,

even for advanced extraterrestrial beings?

Or might their level of technical sophistication

be beyond our wildest dreams?

Simply because it is impossible to us

doesn't mean it's impossible for everybody.

And definitely, when it comes to beings out there

who are able to transcend this boundary of time,

it is clear that they are not subject to time

in the way we are subject to it.

NARRATOR: Do some of the ancient myths and legends provide proof

of successful intergalactic time travel,

as ancient astronaut theorists believe?

If so, might time travel have allowed passage for alien beings

as well as humans to and from our world?

Perhaps the answers can be found in a laboratory

deep underground in Geneva, Switzerland.

As far as we know, time travel only exists in science fiction,

but we also know that there are physicists working today

on creating a time machine.

Right, and you have to imagine that, if we're working on this

right now, an advanced ET race

could have already developed time travel technology.

Yeah, I suppose time travel is possible,

but on my way here in my DeLorean,

I got it up to 88 miles an hour,

-and here I am, still in the present. -(laughs)

NARRATOR: Storrs, Connecticut.

January 2012.

In a lab at the University of Connecticut,

theoretical physicist Ronald Mallett

demonstrates his large-scale model of a time machine.

Using a device called a ring laser

that produces a circulating beam of light,

the professor hopes to prove that the twisting light

actually bends space, forming a loop in time.

MALLETT: Now, what's happening here

is that these lasers, even though you can't see it,

they're actually creating a circulating pattern of light.

And that circulating pattern of light

is actually twisting the empty space in here.

The twisting of space will eventually lead

to a twisting of time.

In Einstein's theory, the two are connected.

And that twisting of time will be where time travel's occurring

because if you think of time as being a straight line,

then if we twist space, then what will happen eventually

is that the space will twist time into a loop.

So, breakthrough of my work was to use light

to manipulate time.

And that should allow for the possibility

of going back in time using light.

NARRATOR: Although this is only a prototype,

Mallett believes he may be able to create

a working time machine in as little as ten years.

He believes the energy of the light beams

will produce a gravitational field

strong enough to drag a spinning neutron through time.

Let's say I'll call the spin-up a one.

And I'll call spin-down a zero.

So, imagine I send a stream of neutrons

with spin-up, spin-up, spin-down.

Spin-up. What do you call that? That's binary code.

So, by using the spin of neutrons,

I can send a binary code,

which could be translated into a message.

NARRATOR: But could this technology ultimately be able to send

larger objects through time, like a person or a spacecraft?

Einstein's theory of relativity allowed for something

called the Einstein-Rosen bridge,

which is what we today call a wormhole.

It opened up the possibility that we can travel

from point A on Earth to point B somewhere else in the universe

as if there were nothing in between.

NARRATOR: If the possibility exists to travel instantly from one end

of the universe to another through wormholes,

might there be evidence that such technology

was used in the ancient past?

The ancient Egyptians knew about stargate and wormhole travel.

The evidence that I discovered is

at the Temple of Hathor at Dendera.

When you enter into this temple, you look up on the ceiling,

which is called the astronomical ceiling,

and you see the gods as ascended light beings

traveling on their ships of eternity.

And it suggests to me that the ancients didn't use

the term "wormhole" for these time travel portals

but were clearly talking about the same thing.

NARRATOR: Is it possible, as ancient astronaut theorists believe,

that advanced celestial beings

traveled in time through wormholes on their way to Earth?

Or might they have possessed

an even more advanced time travel technology,

perhaps based on the complex science of quantum physics?

Geneva, Switzerland.

300 feet underground,

in a tunnel more than 16 miles in circumference,

lies the world's greatest particle accelerator,

the Large Hadron Collider.

Completed in 2008

by the European Organization for Nuclear Research,

also known as CERN,

the massive international project

may allow scientists to solve outstanding scientific mysteries

concerning the creation of the universe.

DENNIN: The Large Hadron Collider is a machine we use in science

to study how particles smaller than an atom behave.

The Large Hadron Collider is based on the principle

of accelerating protons, which are

one of the key elements of the nucleus of an atom.

And you want to accelerate them up to very, very high speeds,

basically in a circular motion,

and collide two beams that are moving in opposite directions.

When you make this collision of the particles,

you get a large number of product particles out,

just like when you collide any two objects,

they smash and break into pieces,

the protons break into pieces.

And it allows us to study

the fundamental particles that make up all of matter.

NARRATOR: On December 13, 2011,

scientists working with the Large Hadron Collider

announced their findings of possible evidence

for the existence of the Higgs boson,

or what some refer to as the "God particle."

MALLETT: A number of physicists have discovered that there is a link

between the four forces of nature that we believe exist.

And you might say the glue that holds these together,

we believe, is this Higgs particle.

It gives particles their mass,

and it also is the thing that helps to bind the forces,

so discovering this God particle

is a way of understanding

the possible unification of the forces of nature.

NARRATOR: Some scientists believe the discovery

of the so-called God particle

may lead to the creation of the Higgs singlet...

...a particle believed to possess the ability

to jump into another dimension,

move forward or backward in time,

and appear in the future or past.

In other words, it would make time travel possible.

SEAGER: We live in a three-dimensional world,

and sometimes people consider time a fourth dimension.

But some theories in physics-- string theory--

predict that there are many, many more dimensions.

Ten or 11 dimensions altogether.

Only these dimensions are not accessible to us.

We don't see them.

Now, these dimensions are tiny,

subatomic, smaller than particles inside of an atom.

And if you could somehow travel along these other dimensions,

it would take you somewhere else entirely.

NARRATOR: Could other dimensions really exist

that we are not yet able to perceive?

If so, might advanced beings

from a distant galaxy have already mastered and utilized

the God particle to visit Earth,

as ancient astronaut theorists suggest?

TSOUKALOS: If you place a picture side by side

of the Hadron Collider and the Aztec calendar,

there's an eerie similarity between the two.

The Aztec calendar was known to be

a gateway to the universe.

And the Hadron Collider is similar to that

because we are trying to unlock

the secrets of the universe with this machine.

And I find it fascinating that we have a carving

from a long time ago,

and when compared to the modern-day Hadron Collider,

there is an eerie similarity.

Is it coincidence? I think not.

NARRATOR: Did ancient man really make contact

with early time travelers?

And are humans on the verge

of discovering that same incredible ability?

Perhaps further evidence can be found by examining

a 20th century account of accidental time travel.

I find it fascinating that two of the most prominent scientists

of the 20th century-- Nikola Tesla and Albert Einstein--

both considered time travel to be possible.

Right, and allegedly, the two of them worked together

on a secret Navy experiment that proved it was possible

-to break through the space-time continuum. -Yeah,

the so-called Philadelphia Experiment.

And the government, of course, claims that it never happened,

but if it did, it could be a breakthrough in time travel.

We talked about this in a 2014 episode

of Ancient Aliens called "The Tesla Experiment."

NARRATOR: New York City. July 1934.

On his 78th birthday, Nikola Tesla makes headlines

on the front page of The New York Times

for his alleged "death beam."

According to the article,

the weapon could generate enough energy to bring down a fleet

of 10,000 enemy airplanes as far as 250 miles away.

JOHN BRANDENBURG: Tesla apparently discovered that he could direct

a stream of plasma plus solid particles

for long distances through the air

and kind of direct a lightning bolt.

And he called this a death ray.

GEORGE NOORY: Tesla wanted to invent a machine that would knock out

enemy aircraft in the air.

You would point it to the skies, turn it on,

and all of a sudden those planes would just

fall like that.

SEIFER: Tesla felt that, if every country

had a particle beam weapon,

then no country would ever be invaded

because planes would be shot down and ships would be sunk.

So he was trying to sell this particle beam weapon

to the U.S. government during World War II.

And I think Franklin Roosevelt

was basically looking at two possibilities.

Einstein was discussing the possibility of an atom bomb.

Tesla was discussing the possibility

of a particle beam weapon.

And it turned out the atom bomb was able to be invented.

And that's the way they went.

NARRATOR: Although the death ray announcement

failed to ignite interest by the U.S. War Department,

some say other innovative work by Tesla

did catch their attention.

Earlier in his career, while conducting research

with one of his transformer coils,

Nikola Tesla had a near-death experience

when he came in contact with a resonating

electromagnetic charge of three and a half million volts.

Tesla was working with 60-foot lightning bolts,

and he made a mistake and he almost got electrocuted.

And he couldn't get out, and he had to get one of his workers

to stop the lightning from happening.

And he barely escaped with his life.

And because of the shock that he had,

he had a revelation.

CHILDRESS: Tesla said that he entered a-a state of timelessness,

and he could see the past and the future and the present

all at one in this mystic vision,

but he was paralyzed and he couldn't do anything about it.

Tesla was being essentially electrocuted,

and right then his assistant cut the power to him.

But what Tesla said it had done

was moved him through time and space.

NARRATOR: But is it really possible

Tesla had found a way to break through

the space-time continuum?

Ancient astronaut theorists

believe the answer might be found by looking

at what has become known as the Philadelphia Experiment.

According to reports, right before Tesla's death,

he was working with Albert Einstein

and the United States Navy

at the Philadelphia Naval Yard

to create an electromagnetically charged

invisibility cloak for the USS Eldridge.

BRANDENBURG: They were attempting to do a stealth technology,

and apparently they mounted a bunch of Tesla coils

to make a bunch of plasma around a ship,

and this is well-known to help hide things from radar.

But something very unexpected happened.

The ship didn't just disappear from radar.

It disappeared completely...

and then reappeared with some of the crew

actually embedded in the metal of the ship.

NARRATOR: Although mainstream scientists believe

the so-called Philadelphia Experiment is a hoax,

some insist the account is authentic.

We have leaked testimony from classified levels

of secrecy in the U.S. government

that the Philadelphia Experiment was real,

that the soldiers on that ship got disoriented

and they ended up walking into the hull.

And when the ship, then, rematerialized in our reality,

their bodies melded with the metal in the hull.

NARRATOR: Could Tesla have discovered the ability to time travel?

If so, might the secrets behind this technology,

along with the blueprints for Tesla's death beam,

have been obtained from a future point in time and space?

Ancient astronaut theorists believe

evidence of this might be found

with the modern world's most sophisticated new weaponry.

NARRATOR: The Singapore Airshow,

February 2014.

An Israeli arms company

known as Rafael Advanced Defense Systems

reveals details of a laser defense system

capable of shooting missiles from the sky

with a pulse of energy.

The futuristic military hardware is called Iron Beam.

REDFERN: The concept of Iron Beam

is that it's essentially a high-energy laser

that is designed to rapidly heat up the target

that it's aimed at.

We're talking about aircraft,

drones, missiles.

Anything that could launch an attack on a city

could be literally destroyed in the sky by Iron Beam.

This sounds very much like Tesla's death ray.

CHILDRESS: This is exactly the kind of technology

that Tesla was talking about in the 1920s and '30s,

of using these beam weapons to shoot down missiles

and projectiles.

WILCOCK: The War Department sided with Einstein

and Oppenheimer's atomic bomb, not with Tesla.

But now what we're seeing is that Israel

is developing this Iron Beam technology

because they realized

that atomic weapons were far too destructive.

Is it possible that Tesla developed

a time-viewing or time travel technology

and that he became aware of these developments?

NARRATOR: Tesla was once quoted as saying,

"The present is theirs,

but the future for which I have really worked is mine."

Did Tesla, in fact, see into the future?

Might Iron Beam be proof

that plans for the death ray not only existed

but also may have even been confiscated

and carried out by the United States government?

There are those who believe that Nikola Tesla

was not only in contact with extraterrestrials

but was sent here to Earth by them to fulfill a mission

and usher in a new age for mankind.

SEIFER: One of the big questions is, who is Tesla?

Is he, in a sense, an avatar,

an enlightened being that comes to the Earth to help humans?

No one really knows exactly what's going on,

but I think all great artists--

and Tesla saw himself as an artist--

feel that they're instruments of a higher purpose,

and Tesla certainly felt

that he was working along those lines.

There is an agenda for humanity.

There is a plan.

And in every generation,

whatever power it is that's behind the plan

sends to Earth certain specific souls

who are, by birth, more inclined

and able to be receptors to the higher knowledge.

CHILDRESS: You have to wonder if Tesla

was transplanted to Earth by extraterrestrials

in order to envision and invent

all of these amazing devices.

WILCOCK: If extraterrestrials put Tesla in place

for a specific purpose,

did they accomplish what they hoped to achieve?

The answer may be no,

because if Tesla's technologies

had been openly acknowledged here on Earth,

we could have greened the deserts,

we could be desalinating ocean water

with tabletop energy levels.

We could have a totally new and different world

in which we don't have to pay for energy,

in which we have antigravity craft,

in which we have teleportation technology,

and in which we truly have become

a golden age here on Earth.

That has not happened.

NARRATOR: Could it be that Nikola Tesla

was able to access advanced technology

by seeing or even traveling into the future?

While mainstream science

tends to dismiss such claims as mere speculation,

Tesla was not alone in encountering a reality

beyond the normal bounds of time.

And even today, there are those who say

they have experienced strange distortions in time and space.

In 2018, I met pilot Bruce Gernon,

who claims that he had a bizarre experience

while flying over the Bermuda Triangle.

And he told me that he entered

some kind of time tunnel vortex

and traveled 100 miles in just three minutes.

Right, there seems to be multiple locations

all around the world where inexplicable events

such as that one seem to be happening all the time.

Yeah, and scientists have speculated,

there could be some exotic physics at play

in these locations and that maybe people really are

getting caught up in these space-time portals.

NARRATOR: Fort Lauderdale, Florida.

December 5, 1945.

Five Navy Avenger torpedo bombers,

collectively known as Flight 19,

set out on a training mission over the Bermuda Triangle.

Without warning, all five bombers

experience malfunctions with their onboard instruments.

They contact air control

and report their mysterious difficulties.

And all five of their compasses were not working correctly,

and they had two navigational instruments that they could use,

and they were not working properly either.

It caused total confusion.

They didn't know their position.

So they did what a lot of other pilots

had done in the past-- they made a series of turns.

And that's what causes pilots to become confused.

NARRATOR: The planes disappeared from radar,

and their last communication

consisted of nothing but eerie static.

The Navy immediately launched two seaplanes

to search for the missing bombers.

Just 20 minutes after takeoff, they, too, vanished.

GERNON: The unusual thing is,

they didn't find any parts.

No life jackets or life rafts.

ANDREW COLLINS: Despite some claims

in more modern times that the Grumman Avengers

have been discovered

that might have been Flight 19,

the actuality of the case is that it is a mystery

of exactly what happened.

NARRATOR: The disappearance of Flight 19

is one of many bizarre and unexplainable events

that have taken place in the area that is now known

as the Bermuda Triangle.

The Bermuda Triangle is really located

off of, uh, Florida.

The northern point of it is the island of Bermuda.

It then goes down to, essentially, Southern Florida

and then out into the Bahamas.

And this is an area that has historically

had strange phenomena.

NARRATOR: For decades, scientists and researchers

have struggled to find a cause

for the mysterious disappearances.

They are equally puzzled by the numerous reports

of everything from instrument failure

to compasses that strangely point to true north

instead of magnetic north.

Electromagnetic phenomenon associated with thunderstorms

that can perhaps open up portals in space-time

and that we never would have thought possible.

An analogy is that lightning...

...is still poorly understood.

Lightning typically carries several million volts.

This is not sufficient voltage to jump from a cloud,

miles above the ground, to the ground or between clouds.

Yet nature does it.

Combine that with the strange location

of the Bermuda Triangle,

where the collision point of these cold and warm currents,

you can have a playground for exotic physics, I believe.

NARRATOR: Might storm clouds, lightning flashes,

and powerful ocean currents

located within the Bermuda Triangle

have unexpected and otherworldly effects?

Ancient astronaut theorists believe

such an audacious theory is possible

and point to the story of pilot Bruce Gernon

as the best evidence that such incredible phenomena

can and do exist.

On December the 4th, 1970,

almost 25 years to the day

after the disappearance of Flight 19...

...a pilot by the name of Bruce Gernon

was in an aircraft flying between Andros Island

and the island of Bimini,

when he had an absolute incredible experience.

The controls on his plane also went crazy.

He felt, in the end, that somehow he had been

in the Bermuda Triangle when it was activated.

Since that time, researchers have been trying to find out

exactly what happened during that flight.

NARRATOR: In March 2018,

ancient astronaut theorist and author David Childress

traveled to an airfield in West Palm Beach, Florida...

-Hi. -...to meet face-to-face

with one of the very few men

who experienced the strange power

of the Bermuda Triangle and survived.

So, what is our plan today?

Well, we're gonna recreate our flight

that I had in, uh, 1970.

And I can show you on the chart here,

we're gonna go direct from Palm Beach

right to this curved area of Andros Island

on the western shore.

And we're gonna go down to 1,000 feet at this point.

And that's where my experience in 1970 began.

I am the only living person that has flown

through the heart of it and then exited what I call

a time tunnel vortex and survived.

So, have you ever retraced your flight?

I've never been on the exact flight path

that I was when I had this event.

And that's what I'd like to take you through today,

the exact flight path.

Into the Bermuda Triangle, and, uh--

this isn't a one-way flight, is it?

ADAM NORWITCH: No, sir, we'll be back.

CHILDRESS: Okay. I'm ready.

So, Bruce, uh, it was,

it was 1970, and you were flying out of Andros.

Who-who was with you on this flight?

Uh, my dad and our business partner was with us,

and it was a routine flight.

But, uh, this is the area

where I, uh, took off and started my ascent.

I was at 1,000 feet just like we are right now.

And I started climbing

straight out over that bank right there.

-There it is. -CHILDRESS: Is that it? Okay.

I don't know, it looks kind of eerie here.

There's nothing much around, is there?

Very remote area of the Bahama Bank.

Whoa, what was that?

Did you feel that?

-Uh... -There it is.

-That-that was a weird... -Can you catch that?

CHILDRESS: Something we should maybe...

Okay. It's out of control?

NORWITCH: It's okay, guys, we just hit a rough spot.

We've just got a little turbulence here.

-Turbulence. -CHILDRESS: How about that?

Yeah. Wow.

I'm-- I have to admit, I'm actually glad

w-we didn't vanish.

That's right in this exact area here...

...where it did that.

Wow, uh, a premonition, maybe.

-Kind of, yeah. -All right, so you--

did you think that anything strange

was gonna happen to you that day?

No, no, I had no premonitions,

but this strange cloud, uh, formed right in front of us,

and it was like a lenticular-shaped cloud.

But it was just sort of hovering there.

And it did look a little strange.

A-As soon as I got over it, it started expanding.

And then, before you know it, I, I'm inside the cloud.

And I-- so now I can't see anything.

Visibility was near zero.

There was lightning in there.

It was flashes of lightning.

These flashes got more and more intense

the deeper we went in it.

It got darker, too. It was almost like night and day.

My copilot-- my dad-- he said,

"Uh, maybe we ought to turn around

and go back to Andros."

I didn't want to turn around

and go back through this cloud

that was freaking me out, you know?

That would've been worse.

There was no turning back, you felt.

I said to my dad, "Well, hold on. Not yet."

NARRATOR: Rather than turning back for land,

Bruce decided to pull out of the cloud

that the plane had become immersed in

and continued on his flight path.

But when he came out of the cloud, he realized

that the situation was even more incredible

than he first thought.

His plane was surrounded on all sides by a giant storm,

and there appeared to be no way out.

I felt like we were trapped inside this strange storm.

And then I notice a big tunnel,

about a mile wide and ten miles long.

So I said, "All right, we'll go through that,"

and, uh, my dad agreed.

When we entered the tunnel, an incredible thing happened.

A series of clouds formed a swirling line

that was slowly rotating counterclockwise.

It felt like we were hydroplaning.

Somehow we were at zero gravity,

we were floating and going forward somehow.

When I came out of the tunnel,

I looked back behind and I watched the tunnel collapse.

The radar controller comes back on the microphone

and he's-he's yelling really loud and he's all excited.

He says, "I got an airplane directly over Miami Beach."

So I look at my watch.

"No, I got another 30 minutes to go here.

"Uh, I'm, uh,

at least 80 miles east of you guys," I tell him.

But then I looked down, and, yeah, there's Miami Beach

right below me.

I traveled 100 miles

in only three minutes.

NARRATOR: One hundred miles

in three minutes?

Bruce's plane would have to have been traveling

2,000 miles per hour

to cross that distance in such a short amount of time,

a speed that his small plane was not even remotely capable of.

But the people on the plane, there-- except for a little bit

of mist and fog around them,

they're-- they don't really notice anything strange

-is happening. -No, they didn't notice anything strange.

But, uh, all their watches were set back 20 minutes.

I believe now that what was happening

was, I-I was seeing the fabric of time.

And I believe that is what creates the mystery

of the Bermuda Triangle.

NARRATOR: Could it be that the so-called tunnel

that Bruce describes

was actually some type of electromagnetic vortex?

One that, like a black hole, could alter both time and space?

For ancient astronaut theorists, the answer

is a resounding yes, and they argue

that even more evidence can be found

by studying ancient disappearances

not only of individuals

but of an entire civilization.

NARRATOR: Easter Island.

Located in the Pacific Ocean,

over 2,000 miles off the coast of Chile,

this remote island was once home to the Rapa Nui people,

who, after flourishing for hundreds of years,

seemed to mysteriously disappear sometime in the 18th century.

It seems, at some point, it may be as much

as 10,000 people lived there at its peak.

But about 100 years later,

when more Europeans started showing up on a regular basis,

it seemed to be down to about 1,500.

So something happened at Easter Island

to seriously decrease their population.

NARRATOR: While mainstream historians have long debated the cause

of the mass disappearance of the Rapa Nui,

ancient astronaut theorists believe

it may have something to do with Easter Island being located

in one of the 12 areas that were identified

by cryptozoologist Ivan T. Sanderson

as "vile vortices,"

places on Earth where strange, electromagnetic activity

is more likely to occur.

We know there are places around the world

that have an unknown energy.

Easter Island,

Mexico, Egypt,

Indus Valley.

Also in Asia. In Tibet.

All around the world, in these areas,

also there were built megalithic structures.

How we can explain that?

The only possible explanation is an ancient contact

with sophisticated alien civilizations around the world.

NARRATOR: Is it possible that because Easter Island,

like the Bermuda Triangle, is located

at a place of increased electromagnetic activity,

that the area serves as a kind of extraterrestrial portal?

A gateway which, when opened,

could allow alien beings to come to Earth

and humans to travel back with them?

Ancient astronaut theorists say yes

and suggest this phenomenon might also happen

in every country on Earth.

Holland, Michigan, February 18, 1978.

Steven Kubacki, a student at Hope College,

tells his roommates he is going out cross-country skiing.

When Steven doesn't return by nightfall,

his roommates contact the police,

and a massive search and rescue operation is launched.

PAULIDES: Two days later, they find Steven's backpack

and his skis sitting

on the beach to the Great Lakes.

And they walk out and they search the area

and they find tracks in the snow

leading out onto the ice towards the lake.

The tracks appeared to stop in the middle of the lake.

There was no hole, there was nothing.

That was just where they stopped.

He completely disappeared.

NARRATOR: A little over a year later,

Steven Kubacki awakens in a field

some 700 miles from where he disappeared.

Certain it was the same day as the one when he went missing,

he had no memory of where he had been

or how he had traveled across the country.

PAULIDES: Where he was for that one year and two months

is a complete black hole.

NARRATOR: After months of investigation,

there was no credible evidence that Steven Kubacki

had staged or faked his disappearance.

So, how was it that a 23-year-old skier

suddenly vanished without a trace,

only to return just over a year later

and with no memory of where he had gone or for how long?

These are the questions currently being answered

by former police detective

turned missing persons investigator

-Dave Paulides. -(phone rings)

-This is Dave. -NARRATOR: For the past nine years,

he has been investigating the world's most baffling

missing persons cases and has concluded

that there are certain places on Earth

where unexplained disappearances occur

in astonishingly high numbers.

I know a lot of people throughout the world have heard

of the Bermuda Triangle,

missing ships and planes over water.

I don't think many people have heard about

the disappearances of people on land

that fit this exact profile that we've established.

Certain profile points replicate themselves

time after time after time.

When they bring in search dogs, bloodhounds,

they can't pick up a scent.

They bring in professional trackers.

They can't track point to point.

Many, many times, there's a weather event

in relationship to the disappearance.

Other times, the person disappears

near a body of water

or is found near a body of water.

Other instances, if the person is found,

they're found in a location

that has been previously searched

not just once, maybe dozens of times.

They leave the searchers scratching their head.

NARRATOR: After examining thousands of missing persons incidents,

Dave Paulides has identified 59 so-called hot spots

in the United States alone.

Places where more people appear to vanish--

and without any signs of foul play--

than anywhere else in the country.

PAULIDES: In the work we do, it's-it's a rare event

that you find somebody who's alive.

But in those instances,

the vast, vast majority of times,

the victim doesn't remember what happened.

They don't know why they got lost,

they don't know where they went,

they don't know where they've been.

I've been very fortunate to meet some of the smartest people

in the world of theoretical physicists,

and during those conversations,

many times it's gone towards portals.

And the response coming back from the physicists was,

"These portals can be directed and targeted."

Is it possible that when people go through

these time tunnel portals

and they have no memory of what went on,

it's because there's nothing for them

to have a memory of

because for them it was just an instantaneous thing?

PAULIDES: So, I'm one of these people, as an investigator,

that lives in the world of facts.

I don't hypothesize, I don't theorize,

and I'm very careful about where I tread

and wh-- who I talk to about these things.

And when you hear from a scientist who's credible,

saying these things could be occurring,

it makes you uncomfortable.

And it makes you wonder, really, what might be going on.

NARRATOR: Could mankind be on the verge of an incredible breakthrough?

Might we soon learn that traveling backwards

and forwards in time is, in fact, possible?

Perhaps further clues can be found

by examining a famous UFO event

reported by military personnel

that involved profound revelations about the future.

When talking about time travel, we have to talk about

that extraordinary event witnessed by dozens of people

at the U.S. Air Force base at Bentwater, in England,

the Rendlesham Forest incident, where two military personnel

who were involved had truly profound experiences.

Yeah, and both claimed to have seen

strange lights in the forest,

and then one of them later claimed

to have had a missing-time event,

and the other one claimed to have seen

some kind of a craft as it was sitting in the field.

CHILDRESS: Yeah, and he said that he got

a message that the craft was being piloted

by humans from the future.

We talked about this in a 2022 episode

of Ancient Aliens called "The Time Benders."

NARRATOR: In Suffolk County, England,

there is a remote forest in the village of Rendlesham

that has become famous for being the site

of one of the most extraordinary UFO encounters ever reported.

And some of those who experienced it

believe this incident also involved time travel.

The event occurred on December 26, 1980.

Airman John Burroughs was performing

a routine security check at a U.S. Air Force base

when he received orders

to investigate a possible downed aircraft.

JOHN BURROUGHS: My supervisor called me on the radio and asked me

to meet up with him so we could check the east gate.

We're driving down the road leading to the east gate

to check on it when all of a sudden he saw

some strange lights in the forest.

So I decided we'll call it in and let them know

something strange was going on.

They decided to send one of the security units down,

which was Sergeant Penniston.

He got down there and he saw the same strange lights

that we were seeing.

SERGEANT JAMES PENNISTON: I could see all these multiple

color lights and things like that.

And the air felt different.

I don't know how to really explain that.

But it did feel like there was electricity

on our skin and hair and stuff.

But that progressively got worse

the closer we got to the tree line.

And it got more intense.

BURROUGHS: There seemed to be, like,

an electricity-charged atmosphere,

and then, also, there were points where there--

it seemed like everything was going in slow motion.

NARRATOR: As the servicemen approached the strange lights,

Sergeant Penniston reportedly saw a large craft

just beyond the tree line.

PENNISTON: The craft was triangular in shape,

measuring about six to seven feet high,

black in color.

I had come around to the far side of the craft,

and that's when I noticed that there was,

you know, inscription on the side.

You know, it was about three feet long,

maybe six inches high, um,

and, uh, so I'm expecting to find, I don't know,

some kind of prototype stuff, uh, USAF.

I'm-I'm looking for something very familiar.

Instead of something familiar,

I see these pictorial-type glyphs.

And got running my hand over the side of the craft.

I don't know how to explain this.

It's like someone was holding a picture up, okay?

I could see it in my mind's eye.

Zeros and ones.

So I recorded those, one after another.

HESELTINE: When Penniston touched

the craft, he then said

that he felt a strange download of information,

uh, to his mind.

And he felt compelled the next day to write down

a series of zeros and ones,

which we now regard as binary code.

POPE: Years later,

a computer programmer took this information,

ran it through a translation program

and a message emerged.

The message read: "Exploration of humanity

"continuous for planetary advance,

"eyes of your eyes,

origin year 8100."

When one sees "origin year 8100,"

one is forced to speculate, might we be looking

not just at extraterrestrials

but time travelers from the future?

NARRATOR: After the incident, the U.S. military

conducted a brief investigation

but allegedly tried to keep the eyewitnesses

away from the press.

But for Airman Burroughs and Officer Penniston,

the event wasn't easy to leave behind.

Both men had lasting physical effects from the encounter

and even reported strange dreams.

After the incident, I started having throat and eye problems.

At one point, my gums turned white.

I also had vision problems,

and when I went and saw the doctor,

one of his first questions was,

had I been ever exposed to radiation?

I've definitely had dreams about it,

and I still have feelings about what happened

and what could happen in the future.

I got out of the service in 1993.

Then I was out about maybe three months,

and then I started getting these dreams

and, uh, nightmares.

During the dreams,

I could see that these were time travelers,

40,000 to 50,000 years in the future.

I see that their purpose to come back

was to correct things, was to fix things.

Something horrible has happened.

Something they have to correct.

But it requires time travel.

It requires going back into the past.

I never had a feeling of it being extraterrestrial.

It's always been

that they were simply us in the future.

NARRATOR: Could it be

that the craft reportedly witnessed

by James Penniston and John Burroughs

came not from a distant star

but from a distant point in time?

Perhaps further clues can be found

by examining trends in evolution

and what humans may look like

in the future.

The great majority of modern-day contactees

describe beings known as the Greys, you know,

large heads, little bodies, gray skin.

To me,

these are clearly extraterrestrials,

but some people have proposed that the Greys potentially

could be future humans.

Right. And some scientists say

that the more time we spend in space,

we might evolve to look just exactly like the Greys.

Yeah, and it's fascinating to contemplate

that we're destined not just to become space travelers

but time travelers, too.

NARRATOR: Ever since the infamous UFO incident

of 1947 in Roswell, New Mexico,

there have been thousands of reports

of extraterrestrial sightings

and even firsthand accounts of alien abductions.

Described as humanoids with large heads and small bodies,

researchers believe these beings might, in fact,

be an alien species that some call the Greys.

BARA: These aliens look not too dissimilar from us.

They have heads, they have hands,

they have two arms, two legs, two eyes,

a nose, a rudimentary mouth.

They certainly, in their descriptions,

appear to be pretty close to us.

Or what they kind of look like

is very, very early science fiction concepts

of how the human race would eventually evolve over the eons.

If you look at the, uh, extraterrestrials

that are described-- the Greys--

that are related to the Roswell incident,

you'll see that, uh,

their forms, in many ways,

resemble what we might project or predict

that we could look like in the future,

uh, if we became a spacefaring race.

CHILDRESS: The Roswell crash in New Mexico,

in fact, happened, coincidentally, close

to the birthday of the Egyptian goddess Isis.

So you have to wonder, too, if these so-called alien bodies

that were allegedly found at the Roswell crash,

with thin bodies and big heads,

if they weren't some kind of

time-traveling extraterrestrials.

NARRATOR: Is it possible the beings

believed to have been recovered at Roswell

traveled here from the star Sirius,

just like the Egyptian goddess Isis,

as some ancient astronaut theorists believe?

And might they be coming here using advanced expertise

in space-time technology?

EDGAR MITCHELL: I would think that it's quite possible

that the alien visitors,

if they're proved to be the way we think they are,

that they're using certain forms of teleportation perhaps,

or certainly they have propulsion devices

that can approach the speed of light.

LINDA MOULTON HOWE: What we do know is that

the physics of our planet--

quantum physics and string theory--

have moved the ball

so much further than it was in the last century

to saying there are no mathematical restrictions

on time travel to the future or to the past.

And that once you know that the physics community

is saying there are no restrictions,

it's just us finding out, "How do we do this?"

CHILDRESS: Time travel is basically the same as teleportation.

We could go from place to place on Earth

in a matter of milliseconds.

This would revolutionize all kinds of travel,

at the same time, our connections between us

and any other civilization,

and including civilizations on other planets as well.

NARRATOR: But just who really are

these otherworldly creatures called the Greys?

Is it possible they came to Earth

not from outer space but from the future...

...or the past?

Or might they actually be human time travelers?

COPPENS: There are various theories as to what the Greys are.

There are stories that they are

beings which have been around since time immemorial

and are still around.

But there are also encounters which people have had,

and in giving these encounters, it has been said

that, really, the Greys are us from the future...

...and that they really have traveled back in time

because somehow we have genetically created

this situation

whereby the Greys are no longer able to procreate...

...and that they have to therefore come back to our times

to sort of remedy the situation.

BARA: People back in the '60s and '70s kind of speculated,

"What would human beings look like

in 1,000 years or 2,000 years?"

And the idea was that we would expand

our intellectual knowledge,

so our brains would get bigger...

...and we'd have machinery that would basically do

all the physical tasks for us that we do with our hands now.

We really would become almost physically inert beings.

And if you look at those early concepts

of the future of the human race, they kind of look like

the standard traditional Grey alien, the Roswell alien.

VON DÄNIKEN: I rather am a believer in time travel.

I say nothing will be impossible for us in the future.

Even if you think it's completely crazy,

it will happen.

Whatever humans are able to think, to calculate,

even to fantasize, will one day become a reality.

Sometimes I ask myself if these UFOs are not time travelers.

It's our own people of the future.

NARRATOR: Considering the scientific advancements

from the last century alone,

might it be possible future humans have discovered

the ability to travel in time,

as some ancient astronaut theorists believe?

Are they, in fact, the so-called visitors

that have been recorded throughout the centuries?

Or are they otherworldly aliens

who have mastered travel through both time and space?

Perhaps the answers can be found not in the here and now

but in another place and time.

If we actually do develop real time travel,

being able to, you know, go through a time tunnel

or a wormhole,

I would like to go back to see

how the pyramids were built in Egypt.

I've always wondered

just how they built those pyramids.

And if you could go back in time, you could maybe see

-how they really did it. -TSOUKALOS: Go ahead.

You go and visit the pyramids.

I would want to go to see Puma Punku,

how Puma Punku was being built, as it was happening.

You know, what type of machines--

and I mean machines-- were used at the time.

I think it'd be fun to be a greeter for the Anunnaki,

you know, when they first arrived...

...to be a part of the welcoming crew

and just see what that might have been actually like.
