_

Extraordinary accounts of missing time.

Once the aircraft
penetrated the tunnel,

time started changing instantly.

It only took three minutes
and 20 seconds

to fly a hundred miles.

Otherworldly events
that seem to alter reality.

It seemed like everything
was going in slow motion,

like everything
was slowing down.

Sightings of strange craft

changing location
instantaneously.

These vehicles are able

to pop in and pop out

of either time
or another dimension.

Could extraterrestrials

have mastered the ability
to travel through time?

Is Earth being visited not only
by entities from other planets

but also from the future,
or even the distant past?

Perhaps an alien civilization
in outer space,

thousands of years
more advanced than us,

may be able to time travel.

There is a doorway

in the universe.

Beyond it is
the promise of truth.

It demands
we question everything

we have ever been taught.

The evidence is all around us.

The future is
right before our eyes.

We are not alone.

We have never been alone.

Mount Pion, Turkey.

Here, where the ancient Greek
city of Ephesus once stood,

lie the ruins
of a religious site

known as the grotto
of the Seven Sleepers.

The grotto is thought
to be the location

where, many centuries ago,

a group of seven men
experienced a shift in time.

In the Christian
and Islamic story

of the Seven Sleepers
of Ephesus,

we learn the amazing story
of seven warriors

who professed Christianity
in 250 AD,

when it was just beginning
to emerge as a new religion.

The Roman emperor offered
these warriors an opportunity

to recant and to disavow
their Christianity.

Instead, they decide
to sell all their possessions

and go into a cave,
and in response,

the-the emperor decides

to seal this cave
with the Sleepers inside of it.

Several hundred years go by,

and a shepherd
chances upon this cave.

And he breaks down the wall,
and the seven people

inside of the cave have been
sleeping for hundreds of years,

and it's now 300 years later.

And they're still alive,
these Seven Sleepers.

These Sleepers
then go into Ephesus...

...and nothing looks the same.

Something they noticed
is that there are

Christian crosses everywhere,

because by now,
Christianity has taken over.

With the Seven
Sleepers of Ephesus you think,

"Okay, is it that there's
some miracle here,"

or have they been in a place
where the time line,

you know, has-has shifted,
and so,

what seems 300 years to them

has been a much
shorter amount of time.

While many scholars
regard this story as fictional,

millions of Christians
and Muslims believe

a true miracle took place,
and that these seven warriors

were transported
into the future.

In fact, hundreds of graves
have been found at the grotto

dating back
to the fifth century,

along with inscriptions
indicating

that people were buried there
because it was considered

a location of great power.

Today, it remains
a popular pilgrimage site,

serving as a testament
to humankind's preoccupation

with one of the most significant
and least understood forces

in the universe: time.

What is time?
That's a great question.

It's a fundamental question.

We all normally live

along the straight line of time,

from the past, present,
to the future.

But the question is,
is there a way around that,

a way to travel through time?

Time is important to us.

The passage of time
is an item of grief

that we all know is universal.

We have a kind of longing
to defeat time.

Why has time travel
stuck around for so long

in human consciousness?

I think this idea that you can
go into the ancient past

or travel into the future
is the ultimate trip.

The notion of breaking free from
the seemingly inescapable bonds

of time has existed in the human
imagination for centuries.

But modern concepts of time
travel are largely credited

to science fiction author
H.G. Wells,

who, in his 1895 book
The Time Machine, speculated

as to how time travel might
be scientifically possible.

H.G. Wells
began to say to himself,

"If we can move in space,
why can't we move in time?"

And that's the beginning
of his novel The Time Machine.

H.G. Wells said it takes
three coordinates

to locate an object in space.

Time, therefore,
is the fourth dimension.

We need four coordinates
to identify

any event in our universe.

H.G. Wells talked about

the idea that space and time
were somehow linked together.

And the protagonist of the book
was able to go, at will,

any time into the future
or any time into the past,

to actually experience
and see what was going on.

Could humankind one day
be able to travel back in time

or even into the future?

Incredibly, just a decade
after the publication

of The Time Machine,

Albert Einstein proposed
a similar vision of time travel.

H.G. Wells, in 1895,

mentioned the idea of time
and space being connected.

Now, this is interesting,
because Albert Einstein

came up with
the theory of relativity,

where he also proposed that
time and space are connected.

Time used to be thought of
in Newtonian classical physics

as something absolute.

It didn't change,
it was the same

for everybody everywhere.

Einstein came along in 1905,

published a paper
on special relativity,

and demonstrated
that time's actually relative.

Now, in Einstein's theory,

space and time
are linked to each other.

That's why it's called
spacetime.

Whatever you do to space
also happens to time.

A rotating black hole
can cause a twisting of space.

Time is linked to space.

So if I'm twisting space,
I can twist time.

Mathematically,
this has been shown.

I can travel from the future
back into the past.

We haven't been able
to do it yet experimentally,

but it's a real part
of Einstein's

general theory of relativity.

Is it possible that spacetime

can be manipulated
to travel into the past?

And if so,
how close is modern science

to achieving
such an incredible feat?

The University
of Connecticut, 2021.

Theoretical physicist
and professor Dr. Ronald Mallett

works closely with a team
of researchers on a project

to realize his lifelong dream:

the creation of a time machine.

By using a mechanism
called a ring laser,

Dr. Mallett believes that he can
manipulate the fabric of space

and time to create a door
that can open to the past.

What I did was I solved

Einstein's gravitational
field equations,

and I was able to show
that a circulating beam

of laser light will cause
a twisting of space.

There is a device,
it's called a ring laser.

All it is is a device
that causes light

to move around in a loop.

You can get it to do that
in a number of different ways.

Bouncing it off mirrors,
for example.

And I was able to show
that a circulating beam

of laser light will cause
a twisting of space.

What I was able to show further
is that if this twisting

of space was strong enough,

it could lead to time
being twisted into a loop.

And these loops in time
could allow for the possibility

of time travel in the past.

This is all anchored
in Einstein's

general theory of relativity.

While Dr. Mallett's time machine

may be theoretically sound,

one major hurdle
stands in his way:

harnessing massive amounts
of energy.

The real constraint

with a time machine
at the moment

is the energy involved,
because you have to bend

the dimension that's time.

The energy at which
you can create

a gateway through space and time
is called the Planck energy.

The Planck energy
is a quadrillion times

more powerful than
our most powerful machine,

the Large Hadron Collider.

We're talking about
the energy of a star.

Perhaps an alien civilization
in outer space,

thousands of years
more advanced than us,

may be able to access
the Planck energy.

That cannot be ruled out.

If extraterrestrial
civilizations

have the technology to traverse
the vast distances of space,

as ancient astronaut
theorists suggest,

might they have also
mastered the ability

to travel through time?

Perhaps further clues
can be found

by examining incredible stories
of time travel

found in some of the earliest
texts ever written.

After a record-breaking 340 days

abord the International
Space Station,

astronaut Scott Kelly returns to
the NASA Johnson Space Center.

The mission was designed
to help researchers

understand the effects
of long-term spaceflight

on the human body.

Scott's identical twin brother
and former astronaut Mark Kelly

remained on Earth to serve
as the control subject.

While Scott was in space,

his immune system
was more active,

his vision deteriorated

and he lost more bone mass
compared to Mark.

But perhaps
the most significant difference

was that for Scott,
time had slowed down.

When they measured the aging
acceleration of Scott Kelly

and Mark Kelly, the twins,
it turns out

that Scott was 0.5 milliseconds
younger than Mark.

And so, what's going on here?

So, that actually fits
with time dilation.

It's a phenomenon that
we have observed to be real,

that the closer you go
to the speed of light,

the more time
slows down for you.

According to Einstein's theory

of special relativity,

the faster you move,
the slower time gets.

So, if you have a telescope
and could look inside

a rocket ship speeding
near the speed of light,

everyone inside that rocket
would be frozen,

moving at a different rate
in time.

Given that the space station
orbits around the planet Earth

at about 17,500 miles per hour,

you can actually calculate
how slow time must be

on the space station.

And so, we can actually measure
this effect in the laboratory.

Imagine, in the future,
when we have rockets that can go

close to the speed of light.

They could find that days,
maybe years had passed

for the people
on board the rocket.

But when they come back,
they would find out

that decades had passed
here on the Earth.

They could come back and find

that they are younger
than their children.

Time travel
to the future is real.

We've seen the baby steps of it.
But it has happened.

If space travel
has revealed to humankind

the possibilities that exist
for manipulating time,

is it possible that somewhere

in the vast expanse
of the universe,

other intelligent beings
have advanced to the point

where they are able to move
through time as easily as space?

Ancient astronaut theorists
believe evidence can be found

in ancient texts
that our ancestors

may have already witnessed

or even experienced
the bending of time.

There's this
wonderful book of stories,

an epic in Hindu culture,
the Mahabharata,

written in the third century
before the Common Era,

but this was writing down
oral traditions

that were much,
much older than that.

And one of the tales
is when King Raivata

goes up into the heavens
and meets God,

the great creator god
Brahma himself.

King Raivata was actually taken
into the heavens in a chariot

to visit this gigantic palace
that was in the celestial realm.

And when King Raivata came back,
much to his surprise,

he did not recognize
a single person

that was in his neighborhood.

In fact, it turns out
that he had returned

hundreds of years later.

Now, how is such
a thing even possible?

Here we have

what is perhaps the first story

of time dilation,

where someone has
gone up into space,

in, say, a spaceship,
and all this time has passed.

Which is exactly what Einstein
had talked about in 1905.

Only, this is a story
from thousands of years ago.

Could King Raivata's experience
be a historical account

of a time dilation event

that occurred
thousands of years ago?

For ancient astronaut theorists,

this possibility
is made stronger

when considering the fact
that similar stories

were told in other parts
of the world...

like in Egypt,
where ancient hieroglyphs

describe a celestial craft
called the solar barge of Ra.

There are many references
in ancient Egypt

about Ra's solar barge,
which was this vehicle

that they described
that they saw cross the sky.

This solar barge is also known
as the Ship of a Million Years.

According to an ancient document
known as the Turin King List,

which contains a record
of all Egyptian rulers

up until 1300 BC,

the earliest pharaohs
lived for hundreds

or even thousands of years.

These were the pharaohs
who were said to have journeyed

to the stars
on the solar barge of Ra.

You look
at some of these records

from the Egyptians
and you think,

well, okay,
if there is this phenomenon

of time dilation, if these
pharaohs really are travelling

on craft at very high speeds,
then when they come back,

they're still young,
the Earth has aged tremendously,

and so, is that part of it?

Is that how you have pharaohs
that lived hundreds of years?

You see this effect
that we now call time dilation

in various ancient cultures.

There is an artifact
at the Ashmolean Museum

in Oxford, England
that is called

the WB44 Kings List
of ancient Sumeria.

It lists the exact
reigning periods

of all the kings
of ancient Sumeria.

The total is 266,000 years,

and there are
crazy reigning periods

that are recorded
very specifically,

and I think they knew perfectly
well how to record time.

You have these figures
in the Bible

that live for hundreds
of-of years.

The oldest figure
in the Bible is Methuselah,

the grandfather of Noah,

and he dies, the Bible tells us,
the age of 969.

According to the Hebrew Bible,

Methuselah's father Enoch

left the Earth
in a fiery chariot,

and was 365 years old

when God chose for him
to remain in the heavenly realm.

All other pre-flood Patriarchs

are recorded as living
for more than 700 years.

Certainly one way
that they would be able to have

these incredibly extended
lives would be

that they are traveling
through space

and coming back and therefore,

400, 900 years can go by,

and-and t-that's essentially
their age on Earth.

These concepts

should not be described
by our ancestors

because it should have exceeded
their knowledge at the time,

but the fact
that multiple stories exist

where someone wakes up
or gets returned

hundreds of years
after certain events...

that's strange.

Could these stories
be historical accounts

of ancient people
experiencing time dilation

after traveling
aboard alien spacecraft?

Ancient astronaut
theorists say yes,

and suggest other accounts,
both ancient and modern,

may reveal
that extraterrestrials

have the ability
to manipulate time

in even more extraordinary ways.

Royal Air Force Wing Commander
Sir Robert Victor Goddard

is dispatched to inspect
an old, disused airfield

near Edinburgh, Scotland.

Sir Robert Victor Goddard
was flying over an airfield

to survey and see
if the airfield could be used

in the future,

and while he's flying over it,
he noticed there's cracks

in the airfield
and there's grass growing up

and cows are eating
the grass and so on.

He's flying home
and he gets kind of lost,

or turned around a bit
in a storm,

so he decides to fly back to
where he was to get a bearing.

On the return journey,
he encountered very strange, uh,

yellow and brown clouds.

Almost like he entered into some
kind of otherworldly portal.

And he came out of there

and found himself
in bright sunlight.

And going over
the same airfield,

everything was renovated.

And there were aircraft
out there on the tarmac.

But they were painted yellow.

And there were people tending
these aircraft dressed in blue.

When Goddard landed

and told his colleagues
what he saw,

they insisted
it was not possible,

since RAF planes were
painted silver at that time

and mechanics' uniforms
were tan-colored.

However, just a few years later,

the RAF changed the color
of both their training planes

and mechanics uniforms,
which Goddard witnessed

when he flew over
Drem airfield again in 1939.

He's making
another flight and realizes,

"There are the planes, at Drem.

"They are painting them yellow.

The people have on
blue uniforms."

It is exactly
what he remembered seeing

when he came out
from beyond this yellow cloud

four years before in 1935.

Some people have suggested

that Victor Goddard's experience

could be extraterrestrial
in nature, and that, just maybe,

he was thrust through time

by a yellow and brown cloud
that he encountered.

There are many examples
of these weird clouds

being encountered
in different parts of the world.

Ancient astronaut
theorists propose

that an alien civilization
advanced enough

to achieve interstellar travel
may also possess the technology

to create portals through time.

And they suggest further
evidence that such gateways

have been established
here on Earth can be found

by examining
the extraordinary events

that have occurred
in the Bermuda Triangle.

At 3:00 in the afternoon,

pilot Bruce Gernon
departs from Andros Island

bound for Palm Beach, Florida,
just north of Miami.

It's a route that he's flown

many times before
without incident,

but this flight
will be unlike any other.

Since I've been flying
for 47 years now, uh...

I've had a lot of flights
in that area.

But this experience
I'll never forget.

It all started a hundred miles
east of Miami

when I found myself surrounded
by this strange storm.

Time started changing instantly.

And I believe I actually got to
see the fabric of time itself

as I watched the tunnel rotate.

When I reached the other end,
the tunnel collapsed.

And I reached the shoreline
of Miami Beach.

It only took three minutes
and 20 seconds

to fly a hundred miles.

I should have been able to fly
only ten miles, approximately.

Not 100 miles.

I think that what
he must have experienced

is perhaps some kind
of a time shift,

or he entered
into an anomalous vortex

that perhaps was
some kind of a time portal.

We don't know, but it's a very
curious example of time travel.

Could it be

that the route
Bruce Gernon traveled

led him into
a portal through time?

As far as ancient astronaut
theorists are concerned,

this incredible possibility
is even more intriguing

because of the area where it
happened, 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 phenomenon.

While Gernon was
fortunate enough

to have survived
his harrowing experience,

many ships and aircraft
traveling through this region

have disappeared
without a trace.

In one extraordinary case

that occurred
on December 5, 1945,

five Navy Avenger
torpedo bombers,

known as Flight 19, all went
missing at the same time.

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.

The planes
disappeared from radar,

and their last communication

consisted of nothing
but eerie static.

The Navy immediately sent
a team to search

for the missing bombers, but
they never recovered any debris.

Is it possible
that the Bermuda Triangle

is subject to portals
or vortexes

that create these mysteries?

What we do know
is that it is a place

of intensive
electromagnetic activity,

and this is something
that we can tell

from the fact that
so many aircraft and ships

experience problems
with their instrumentation.

Might the Bermuda Triangle
be an electromagnetic hot spot

where portals
capable of manipulating time

open and close?

Ancient astronaut
theorists say yes,

and they believe that
these portals may help explain

some of the strange,
otherworldly activity

reported in the area.

Many UFO sightings

and m-more modern
UAP, uh, videos

have been released show unusual
flight dynamics and capabilities

of these... whatever they are.

Well, it may be
they're creating portals,

in our universe
and in our time and our space,

that they can move
in and out of, uh, at will.

There's no reason
to, uh, say they can't

until we know what they are.

Is it possible that visitors

from other worlds
are utilizing portals

in the Bermuda Triangle

to travel through time
and space?

And if so, do such portals
already exist naturally,

or are they being created

with some type
of extraterrestrial technology?

Perhaps the answer can be found

by examining the account
of a UFO witness who claims

to have received
a message from the future.

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.

My supervisor called me
on the radio and asked

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.

So it was Sergeant Penniston.

He got down there and he saw
the same strange lights

that we were seeing.

So 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.

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.

As the servicemen approached
the strange lights,

Sergeant Penniston
reportedly saw a large craft

just beyond the tree line.

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 is 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.

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.

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?

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 nightmares.

During the dreams,

I could see that these
were time travelers,

40 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.

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.

If we look at past trends

in our biological form,

we see that we're likely
to look very similar

to what's
most commonly described

in these instances
of close encounters.

Butte, Montana, 2019.

Professor
of biological anthropology

at Montana
Technological University,

Dr. Michael Masters publishes
Identified Flying Objects.

This groundbreaking book
explores the profound notion

that the UFO phenomenon
may involve

our distant human descendants

traveling backward
across the landscape of time.

One of the big questions about

backward time travel
is why aren't we inundated

by time tourists
if backward time travel exists?

And the answer
may simply be, we do.

We do see them,
in the form of UFOs,

in the form of these
"alien beings"

that are most likely
traveling backwards

from the human future,
using more advanced technology

and with a more
advanced physical form

than what we have now.

Dr. Masters points out

that current accounts
of humanoid aliens,

the Greys in particular,
bear a striking resemblance

to what many biologists
predict humans may look like

in the distant future.

If we look at past trends
in our biological form

and in our technology,

we see the same dominant trends
in our morphology.

Our neurocrania have become
enlarged, becoming more rounded.

Our midfacial and lower
facial anatomy has retracted.

If these are to continue
into the future,

we're likely
to look very similar

to what's most
commonly described

in these instances
of close encounters,

where the being have big heads,
small faces, big eyes.

Many of the types
of aliens, if you like,

or strange beings
that are in these crafts,

they're often taller,
they've got larger heads,

larger eyes, and that
could be a sign of evolution

of our species going thousands

or possibly hundreds
of thousands of years

into the future.

Could the so-called Grey aliens

that many people believe
they have encountered

actually be
human time travelers?

According to some researchers,
further evidence

that Earth is being visited
by future humans can be found

by examining accounts
of unidentified flying objects.

If we look at the craft, too,

they seem to have a form
that indicates the function

of backward time travel.

It's very consistent
with research

since Einstein's paper in 1915,
demonstrating how the rotation

of a massive or highly
energetic disc or cylinder

could create backward
time travel capabilities.

Sometimes I ask myself

if UFOs are not time travelers.

It's our own, uh,
people of the future

who study some history
and they send some vehicles

to measure, to observe,
to photograph us.

But they don't make
direct contact.

So I would exclude nothing,
not even time travel.

But if future humans
have traveled back in time,

are they simply observing
events of the past?

Or could they have
a more profound agenda?

One of the other ideas
relating to this is the idea

that our selves from the future

are actually trying
to help us in some way.

There's some kind
of interaction going on.

They could be
giving us information

about advances in technology.

They could be giving us
information about other planets.

They could be giving us
scientific data

that we need to survive

that they know
about in the future,

but y... we're yet
to get to that point.

Could they be coming back

to help evolve us in some way,

to help us learn new
technologies and innovations?

Perhaps to steer us
towards their own future.

Maybe these technologies
involve everything

from quantum computers
to nuclear fusion

to AI and even nanotechnology.

All of these are
at the cutting edge of science,

and we are actually
looking for answers

to how to better perfect
these technologies.

If UFOs are craft

from our future, if the beings
seen in association with them

are our distant descendants,

and they crashed into
Roswell, New Mexico in 1947,

it's possible that we've
been reverse-engineering

this technology.

And not just for the purposes
of flying through space

at tremendous speeds

or having antigravity
propulsion systems,

but also, potentially, to figure
out how to travel through time.

We may be eventually
reaching the point

where that technology is ours,
coming back through time again,

where there's this constant loop
through the past and the future.

If time travel is possible,

could it be that Earth
is being visited

by both extraterrestrials
and humans from our own future?

Perhaps further clues
can be found

by examining the possibility

that the true nature of time
is much different than we think.

Housed at the National Institute

of Standards and Technology

are two atomic clocks
that together serve

as the United States' primary
time and frequency standard.

Around the world, similar clocks
with incredible precision

set the time by which
all of humankind operates.

It is a relentless march
of seconds, minutes, hours

and days determining
when we wake up,

go to work, eat,
sleep, celebrate

and ultimately, die.

But what if how we perceive time

is nothing more
than a human construct?

An attempt to quantify
and control a universal force

that modern science
hasn't even begun to understand?

We live in the fantasy
of linear time,

because we have to remember

that all the notions of time
are imposed on reality.

Reality flows in its own way.

We imagine
that our clocks measure it.

We claim to be able
to mark it off

in hours and days and things,

but that's all just
imposed on it.

Physicists point out

that going by modern science's
linear concept of time,

even the idea of the here
and now is merely an illusion,

since light and sound
do not travel instantaneously.

When you look at a mirror,
you're not really looking

at yourself as you are,
you're looking at yourself

as you were about
a billionth of a second ago.

When you look at the Moon,
you're not really looking

at the Moon as it is now.

You're looking at the Moon
as it was about a second ago.

So when you look
at the Pleiades,

you're looking at the Pleiades
as they were 400 years ago.

Some of the stars
viewable in the night sky

burnt out long ago,

which, according
to a linear model of time,

means they no longer exist.

They are no longer reachable.

But what if this model
of time is wrong?

Another take
on time travel is that

when the Big Bang occurred,
all of space and time

and everything is in it
was created.

So all of time
is in the universe already.

For some reason,
we can only experience the now.

Could it be that
our understanding of time

is limited
by how we experience it?

And might a more
technologically-advanced

extraterrestrial species
or even future humans

have discovered how
to manipulate time and space

to travel both to the past
and to the future?

The idea that we may
simply be dealing with

space people
from other star systems

may not be the full answer.

We could be dealing
with time travelers.

Could these intelligences
have been aiding us?

Perhaps guiding us?

Perhaps controlling
the evolution of humanity?

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 reality.

Is Earth being visited
by highly-advanced civilizations

that have overcome the
limitations of time and space?

And if so, could they even be
our own human descendants

traveling back from the future?

Perhaps our notions
of time, space

and our place in the universe

are about to be
radically altered.

Only time will tell.
