William Shatner: You know, I've been around

for a while.

Met some interesting people, done some crazy things.

So you just might think that there's not much that

can take me by surprise.

You'd be wrong.

The world is full of stories and science and

things that amaze and confound me every single

day, incredible mysteries that keep me

awake at night.

Some I can answer.

Others just defy logic.

Do parallel worlds exist?

In New York, a woman has a frightening encounter with

a mysterious shadow shaped like a human.

Was it an entity from another dimension?

Rosemary Guiley: There was something

very sinister about it.

In New Jersey, a boy becomes entangled

in a strange machine...

Andrew Basiago: On the count of three

we jumped through the field of energy.

And ends up in another world.

Does teleportation exist?

And in Mexico, an explorer uncovers a bizarre skull

made of crystal.

Is it a doorway to another universe?

William Shatner: Yeah, it's a weird world.

And I love it.

[♪]

William Shatner: Bubbles! Beautiful, aren't they?

Well guess what?

Scientists believe that we're living in one.

They say that our entire universe is a giant,

perhaps infinite sized one of these.

But if that's hard to comprehend there's

something else - in 2010 scientists found something

extraordinary - evidence that our bubble, our

universe, has been bruised,

not once but four times.

Why? 'Cause it smashed into other bubbles and do you

know what those other bubbles are?

Other universes.

There could be millions of them, parallel worlds,

other dimensions that exist alongside ours.

Amazing isn't it?

But let's think about this.

If it's true that means there could be people or

something like us floating around inside them.

Isn't that a little scary?

Could we, in the distant future, bump into

something or someone from a neighbouring dimension?

Well I've got news for you.

It's happening right now.

Bubbles!

Rosemary Guiley is an author.

In October 2010, she decided to go hiking in

the Fahnestock State Park in New York.

Rosemary Guiley: So I trekked out by myself,

which is not always a good idea, and there

was no one around.

There was no one on the trail and I went out to

what we call the King's Chamber.

The King's Chamber is one of several mysterious

manmade structures in the area.

Rosemary Guiley: Nobody really knows who built

them or why and many people who visit them have

paranormal experiences.

Some think Native Americans made them.

Others believe it was European settlers

or even ancient Druids.

No one knows for sure.

But as Rosemary enters the ruins, she begins

to sense something strange.

Rosemary Guiley: I could sense an unusual presence there.

You have a feeling that there may be something

unseen watching you or that something unusual

is about to happen.

Despite her misgivings, Rosemary presses on.

It's not long before she's sorry she did.

Rosemary Guiley: I became aware of a dark shape

moving through the trees in front of me.

There was something very sinister about it.

This figure was tall and slim and it looked like

the outline of a human being.

It was very dark in colour, inky dark and it

had very blurry edges and the lower portion of it

sort of trailed away.

There's no facial features, no eyes but yet

you know it's looking at you.

You can just feel it and that is a very scary thing.

Was Rosemary's mind playing tricks?

Or was someone or something stalking her

through the King's Chamber?

Rosemary Guiley: This was not an apparition.

You simply know when you are encountering something

that's not quite of this world.

So what was it?

Rosemary didn't wait around to find out.

Rosemary Guiley: It wa like one of those movies

where bad things are happening to people and a

voice says get out.

It's time to go.

What did Rosemary Guiley see?

Was she in real danger from a shadow?

Or was it something even more sinister?

Incredibly, her experience is not unique.

Hundreds have reported encounters with dark

humanoid transparent creatures.

They call them shadow people.

But what are they?

Rosemary has come to an incredible conclusion.

Rosemary Guiley: Shadow people come from other

dimensions, parallel dimensions that are right

here on this planet.

They're just around a certain bend in space

where we can't normally see them except under the

right circumstances.

Are shadow people intruders from

a parallel dimension?

If so, how did they cross into our world

and what do they want?

Chris French is a psychologist.

He believes there is a simple explanation.

Christopher French: These shadow people

are just shadows.

The way that these shadow people are said to move is

kind of a very fleeting motion.

One moment they're there, the next moment,

they're somewhere else.

I mean, to me, it sounds very much like the way

that shadows move.

Are shadow people simply random shadows?

If so, what gives them such distinct human shapes?

French believes the answer lies in a phenomenon

called pareidolia.

Christopher French: Pareidolia refers

specifically to this idea that we can sometimes

think we see clear and distinct human forms in

what is essentially just random background noise.

I think everybody's probably had the

experience of looking at patterns on wallpaper and

making out faces in those patterns.

Or we look up in the clouds and we see animal shapes.

People have found images of Christ in plates of

spaghetti, in cinnamon buns, in the burn marks

on tortillas.

What you've got are really kind of more or less

random patterns but we will impose some

kind of meaning on them.

People tend to experience shadow people in certain

kinds of locations.

If you are in a forest, if you're in a cave, if

you're in somewhere where there's lots of shadows,

then those are precisely the kind of random

background visual noise situations where you might

actually think you can see things that aren't there.

But many who have encountered shadow people

feel physically threatened.

Why?

Christopher French: I think one of the reasons

that people often perceive these things as being

something potentially threatening is because

that's the way we've evolved.

You know, some guy back in the Stone Age and he

thinks that there might be a saber tooth tiger

in that bush.

On the one hand, you've got the guy who very

quickly decides it's a saber tooth tiger

and runs away.

You've got the other guy who stands there

scratching his beard wondering whether it

really is a saber tooth tiger.

He gets eaten.

So who's going to pass on their genes?

We've evolved to survive.

Are our survival instincts tricking us into believing

a shadow is a terrifying and real creature?

Christopher French: It's an extremely common

phenomenon for perfectly sane people to sometimes

see things that aren't actually there.

There are parts of the brain that are hard wired

to recognize faces and human forms and so

sometimes those parts of the brain will actually

fire when what we're looking at

are really just shadows.

Are shadow people simply shadows?

Rosemary Guiley isn't convinced.

Rosemary Guiley: It was not a trick

of my imagination.

It was unmistakable, a black shape moving

through the trees.

William Shatner: You know it's amazing how real

shadows can appear.

But could something like this be a terrifying

shadow creature from another dimension

that's come to pay us a visit?

Did you do that Fluffy?

So who exactly are shadow people?

Where do they come from?

One man believes he has the answer.

Philip Imbrogno: They belong to a race of beings

that predates human beings.

They exist in a dimension very close to oursrs.

A woman has a terrifying encounter with a

human-like shadow.

Was it a trick of her mind or a visitor from a

parallel world?

Philip Imbrogno is a paranormal researcher.

He thinks the answer is clear.

Philip Imbrogno: From the cases that I've studied

about shadow people, I believe they are

inter-dimensional in nature.

They're intelligent.

They belong to a race of beings that

predates human beings.

They exist in a dimension very close to ours.

It's an incredible theory but it begs one big question.

How can we know these other dimensions exist?

Imbrogno believes the answer lies with the force

of gravity and its component part,

the graviton.

Philip Imbrogno: A graviton is a theoretical

particle that ties the entire universe together.

Gravitons flow through the dimensions just like a,

a wave, These particles have a pull,

like a magnetic pull.

Philip Imbrogno: The gravity coming from our

sun, reaching the earth, should theoretically tear

the earth apart but it doesn't.

If all of these gravitons being emitted from the sun

were filtered through multi-dimensions before

they reach us, it could give us an indication that

these other extra dimensions do in fact exist.

If that sounds like gobbledygook, here's the

simple version.

Imbrogno thinks gravity is being weakened as it

travels from the sun to earth because it's being

diffused as it passes through - yeah,

you guessed it - other dimensions that are home

to shadow people.

It's an extraordinary and somewhat crazy idea.

But if there are other dimensions surrounding

ours, how are shadow people traveling between them

- and to us?

Philip Imbrogno: Shadow people may understand the

concept of gravitons more than we do.

Their technology has been around thousands and

thousands of years before human beings.

So they may understand that they may have to

focus gravitons at a particular area to open up

a portal to lead into our reality.

According to Imbrogno, he will soon have hard

scientific evidence to support his theory.

Philip Imbrogno: When these dimensions are

opened up, we should see an influx of gravitons.

This interaction can be measured.

So the exciting research that I'm involved in right

now is building devices that would be able to

detect large amounts of gravitons to predict when

shadow people would appear.

Are shadow people using gravity to open portals

to our dimension?

And, if so, what do they want?

Philip Imbrogno: It seems to me that the main

objective of, of the shadow person's visit is

to learn about us as much as they can

by observing us.

Some people would find that very unsettling.

I would like to think that they just discovered us

and they're as curious about us as we are about

them and perhaps some day in the future they may

make their presence known to us and try to coexist

with us since we are neighbours.

Did Rosemary Guiley encounter a curious shadow person?

Are we facing an invasion of beings from a

neighbouring dimension?

Should we be afraid?

Very afraid?

Or are they nothing but a trick of light?

Weird or what?

[♪]

William Shatner: You know, I uh used to get into a

lot of sticky situations during our voyages on the

Starship uh Enterprise but I was always able to get

out of them like this.

Ah see what I, I just did there?

And I didn't even have Scotty to beam me up.

But can we somehow transport ourselves from

one location to another in an instant?

Things like that are science fiction, right?

Wrong.

1960. Suburban New Jersey.

Six-year-old Andrew Basiago is about to have

the most incredible day of his life.

Andrew Basiago: My dad called out to my mother

and said hon, I'm taking Andy to the hardware store.

Instead, he drove me up to the old aeronautical

company facility in Wood-Ridge, New Jersey,

a large defense technical experimental area that

dated back to World War Two.

As they enter the facility, Andrew wonders

why his father Frank would bring him to a place like this.

Andrew Basiago: I didn't know what was happening.

Andrew's dad leads him to a secret room.

Inside is something unlike anything he's ever seen before.

Andrew Basiago: It was so strange.

It essentially consisted of two elliptical shaped

booms that were about eight feet tall

and about ten feet across.

It's a machine that's beyond Andrew's comprehension.

Whatever it is, his father is clearly in charge.

But why?

And what is it for?

Andrew Basiago: He had the technician turn the device on.

As Andrew watches, the booms begin to spin,

generating a strange cascade of energy.

Andrew Basiago: It looked almost like water falling

in a public fountain.

It was a very beautiful sort of shimmering field of energy.

As the energy field from the machine grows,

Andrew's dad does something incredible.

He tells his son to take his hand.

Then, the unimaginable happens.

Andrew Basiago: We counted down, you know,

one, two, three.

On the count of three we jumped through

the field of energy.

We seemed to be moving and I could ultimately see a

point of light in the distance and that light

reached us very quickly and accelerated and when

the light hit us we were elsewhere in the country.

Now my father didn't tell me where we were going.

In fact, we were jumping two thousand, five miles

through this vortal tunnel in the fabric of

time-space to the State Capitol grounds in

Santa Fe, New Mexico.

It's an astonishing claim.

Did two humans actually transport from New Jersey

to New Mexico in the blink of an eye?

What happened to Andrew and his father?

Is his story just the wild fantasy of a six year old?

Basiago believes there is only one answer.

Andrew Basiago: I think I must have teleported.

Imagine traveling through the Lincoln Tunnel in

New York City at ten thousand miles per hour without any

automobile around you.

That's sort of what it was like.

We were physically moving through a vortal tunnel in

the fabric of time-space.

Had Andrew's father Frank invented the world's first

teleportation machine?

And, if so, why?

Frank Basiago was no ordinary dad.

During the Cold War, the US and Soviets raced for

military superiority.

Frank was head of a top secret American research

team who were conducting experiments into

teleportation.

But why did Frank use his son as a guinea pig?

Andrew Basiago: I think my dad's immediate goal in

inviting me to teleport was to show that if

teleportation was safe for his son it was safe

for anybody's child.

And I was in it as a child just as, for example,

a child may have been aboard, you know, one of

Columbus' boats or may have been an office boy to

the Wright brothers, or an assistant

to Thomas Alva Edison.

After the success of the experiment, Frank Basiago

decides teleportation is too important to keep secret.

He wants to tell the world, but the

US military disagrees.

Andrew Basiago: And so the, the unfortunate

history of US teleportation is that it

has remained essentially a military secret ever since.

Forty years later, Andrew is on a mission.

He believes teleportation technology

is vitally important.

His father's invention should

be available to all of us.

Andrew Basiago: Today I'm leading the truth campaign.

I'm urging the United States government to

declassify teleportation to allow people to

teleport between major world cities.

The way I see it, I have a duty simply to stand in

my truth and tell it, tell the truth about what

happened because this was clearly an important

epoch in the history of applied science.

This was the moment when our human civilization on

Earth became a time-space faring civilization.

Did Frank Basiago invent a machine that could

instantly transport us across the world or even

to other dimensions?

Is teleportation possible?

Raymond Laflamme: I wouldn't like to be

the first one to be teleported.

I would worry to end up maybe like a Picasso painting.

A boy enters a teleportation machine and

is suddenly transported thousands of miles in seconds.

Is human teleportation possible?

Raymond Laflamme is a physicist.

He thinks the idea we can teleport our bodies

is simply fantasy.

Raymond Laflamme: It seem that the laws of physics

are more constrained than the imagination

of human beings.

The first idea that we have when we think about

teleportation is the Star Trek idea - Beam me up

Scotty, the idea of taking a person so they

disintegrate in some form and reappearing up

in a space station.

Now this is something that happens

in science fiction.

But, incredibly, although Laflamme dismisses the

idea that people can teleport, he does believe

it can happen in other ways - because he was one

of the first scientists to do it.

Raymond Laflamme: We're not teleporting matter

from one location to the other.

We're really teleporting information.

Wait a second.

Teleporting information?

How is that any different than sending an email?

Raymond Laflamme: When we send an email or even when

we talk on our cellular phone, the information

goes from the sender, through the intervening

space to a receiver.

Remarkably, Laflamme has been able to teleport

information without it traveling through

any device at all.

Raymond Laflamme: What has been teleported is one

quantum bit of information.

We've been able to teleport a few kilometers

taking one particle of information and make it

reappear a few kilometers down the line.

We've been able to do this.

It works like this.

In the world of quantum physics, even the tiniest

particles are somehow connected - even across

huge distances.

In quantum teleportation, such entangled particles

can literally be in two places at once.

Raymond Laflamme: Absolutely amazing

that we can teleport.

In quantum teleportation it seems to disappear here

and reappear there.

It looks like a piece of magic.

This technology could soon be used to instantly

communicate with spaceships, no matter how

far away - or send military communications

that are impossible to intercept.

Raymond Laflamme: We are just at the beginning of

understanding what is quantum teleportation,

how it works.

We may be able to teleport information, but does

Andrew Basiago's story mean we can do it to ourselves?

Laflamme thinks not.

Raymond Laflamme: He must have a secret that I do

not have to be able to do this but I wouldn't like

to be the first one to be teleported.

I would worry to end up maybe like a Picasso painting.

If human teleportation isn't possible,

what happened to Andrew Basiago?

Was his incredible journey just a figment of

childhood imagination?

Bruce Goldberg is a hypnotherapist.

He thinks stories like Andrew's are very real.

Bruce Goldberg: We have ancient literature going

back thousands of years of people who've teleported.

There are a lot of religious cases but there

are also secular cases too.

I think teleportation exists.

But how?

Goldberg believes he's discovered the secret.

Bruce Goldberg: Teleportation is a very

complex mechanism.

I first discovered teleportation while

working with patients.

People would describe disappearing from one location.

One gentleman went from New York City to Paris

in an instant.

I mean he disappeared.

His wife was sitting in the same room and told me

yeah my husband disappeared.

I don't know where he went and I was right there.

At first, Goldberg doubted his patients.

Bruce Goldberg: So then I started doing research

about the teleportation cases.

These are psychologically stable people.

I know them, I know the families and

they weren't on drugs, okay?

But as he continued his research, Goldberg's

patients began to describe their teleportation

experiences in remarkable detail, and they all had

one thing in common.

Patient: You see first just a little bit like

tunnel vision and then all of a sudden you appear whole.

The people look exactly like we do.

Some of the people that I meet are recognizable.

I know who they are.

Incredibly, the people they encountered were

replicas of - themselves.

The hauntingly similar experiences led Goldberg

to a stunning insight.

Bruce Goldberg: When you teleport you leave this

universe and move into a parallel universe.

Parallel universes are sister universes that

exist alongside ours.

Your DNA is exactly the same in your parallel life

as it is here.

Are Goldberg's patients somehow being sucked into

parallel dimensions and then meeting

their own doppelgangers?

William Shatner: Now this is getting really crazy.

Is there more than one Bill?

Is there more than one you?

Sounds nuts, right?

Incredibly, physicists believe that these

identical copies of ourselves might exist.

Now I don't really understand how this is

possible but if the eggheads say the math

work, who am I to argue?

Do identical copies of each and every one of us

exist in parallel worlds?

Could we even enter those alternate realities?

Bruce Goldberg believes the possibilities

are staggering.

Bruce Goldberg: Let's say you have certain aspects

of your life right now that you cannot change.

Maybe you have an incurable disease.

Maybe you have a criminal record.

Maybe you've lost an arm.

Well in a parallel universe that didn't exist.

So instead of committing suicide or just going

through life being depressed you can actually

switch universes and in fact have a much better life.

But if it really is possible to leap into a

parallel world, why isn't everyone doing it?

Bruce Goldberg: Teleportation is hardly predictable.

You can do this a thousand times and you may get one

or two examples but future technology will be such

that teleportation will be established by machines so

people can control it and do it with regularity

and predictability.

Could such technology already exist?

Could Frank Basiago's dream still be alive?

Bruce Goldberg: I don't doubt there is some

technology that can exist today where somebody can

enter into this like a vortex and they can be

teleported from one place to another.

Do we all exist in other dimensions?

Do we possess machines that can teleport us from

one world to another?

Could Scotty really beam us up after all?

Weird or what?

[♪]

In Mexico, an explorer finds a strange skull

made of pure crystal.

Is it a gateway to another world?

Kirby Seid: Crystal skulls are holographic.

William Shatner: You know I love exploring.

There's nothing better than getting out and

seeing what you can find amongst the wilds of nature.

Uh oh you hear that?

You hear that?

Sometimes you can find treasures beyond the

imagination - but sometimes you find things

you want to keep very secret.

In 1924, British adventurer Frederick

Mitchell-Hedges went in search of Mayan treasures

in the tiny country of Belize in Central America.

What he discovered is regarded by some as the

most important archaeological relic ever found -

a perfectly formed human skull,

made from crystal.

Carved with flawless precision, this

2,000-year-old artifact baffled scientists.

Many believed the technology that created it

couldn't have existed in ancient or even modern times.

So what was it?

And where did it come from?

Remarkably, the answer could lie in an ancient

Mayan legend that speaks of not one but thirteen

crystal skulls that have extraordinary powers.

It's a legend that could be based in fact.

In 1994, amateur archeologist Nick Nocerino

found another perfect life-sized skull,

impeccably carved in clear crystal in Guerrero, Mexico.

Kirby Seid is a crystal and mineral expert.

In 1995, the Guerrero skull came into his care.

As he began to study it, something weird happened.

Kirby Seid: It began to show me pictures of past

lives, it showed me images of possible futures

that I could try to achieve for.

Those pictures turn into visions.

Those visions, I see people moving,

I see objects moving, there's motion in those visions.

And suddenly, I feel like I've popped into

that particular reality.

I feel like I'm merging my energy with its energy.

But Kirby believes this skull has many other powers.

The greatest of all is the ability to open doors

to another world.

Kirby Seid: Crystal skulls are, are holographic.

They contain all the points in time and space.

We know in modern physics theory, in string theory,

that there are at least eleven dimensions.

Skulls are portals to other dimensions in

parallel worlds.

Do crystal skulls possess strange powers that can

take us to other dimensions?

Or is there another answer to this mystery?

Jane Walsh: Well to my mind there's not really a

mystery surrounding them.

A man believes an ancient crystal skull can

communicate with parallel worlds.

Do these strange mysterious objects have

powers beyond our comprehension?

Jane Walsh: Well to my mind there's not really

a mystery surrounding them.

Jane Walsh is an anthropologist at the

Smithsonian in Washington, DC.

She believes crystal skulls aren't quite

as magical as they seem.

Jane Walsh: I've essentially concluded that

none of the skulls I have looked at have really

anything to do with pre-Columbian Mexico.

Mostly they were marketed to deceive.

Jane has examined nine crystal skulls, including

the one discovered by Mitchell-Hedges.

Due to the nature of the crystal, it's not possible

to determine when the skulls were made but Jane

believes there's another way to unearth

the skulls' secrets.

Using liquid silicone, she can find out

how they were made.

Jane Walsh: The silicone sort of flows in nicely to

all of the crevices.

Make sure it's going into all of the carved areas.

Once the silicone is dry, Jane has a highly accurate

mold of the markings on the skull's surface.

Using an electron microscope, these can be

magnified over ten million times.

Unknown: As those electrons strike the

surface of the sample, we're gonna generate a signal.

We'll get a topographical image of the surface of

the sample and we get great spatial resolution.

We see very good detail.

We can see a lot of things that we wouldn't

be able to see otherwise.

One thing in particular was remarkable - evidence

that the perfect crystal skulls weren't quite as

perfect as they seemed.

Jane Walsh: What you're seeing there is the edge

of a rotary disc cutting tool.

Unknown: If you imagine some guy sitting here

doing this, trying to drill this little hole

we're not gonna have this little path that cuts.

You can follow it all the way around.

Jane's analysis is damning.

She believes whoever made the skulls had access to

modern power tools.

Jane Walsh: We know the sorts of tools that were

used by pre-Columbian lapidaries which was

essentially a Stone Age tool kit.

So with the Mitchell-Hedges skull we

were able to find some of the initial carving that

was done by very tiny high-speed dentist type drills.

That's simply not a tool that any Mayan or Aztec

would have had.

So if the skulls are not ancient Mayan or Aztec,

when were they carved?

Jane Walsh: They probably are about as old as when

they first appeared.

All of them were created by using quite modern tools.

Are the crystal skulls simply an elaborate hoax?

Does the harsh light of Jane's microscope mean we

should dismiss those who believe

they have mystical powers?

Jane Walsh: I would love it if someone would

excavate one, a recognized archeologist but

I'm not holding my breath.

Is the legend of thirteen all-powerful crystal

skulls nothing more than fanciful bunkum?

Or do they have powers beyond comprehension?

Could Kirby Seid be right?

Are they gateways to other dimensions?

Joshua Shapiro is an explorer.

He not only believes crystal skulls can connect

us to other worlds, but they were given to us by

beings who live in them.

Joshua Shapiro: What believe is the connection

between the crystal skulls, and let's say

other intelligences which may come from parallel

worlds or other dimensions.

These beings I believe brought the crystal skulls

in physical form to humanity a very long time ago.

Did crystal skulls arrive from parallel worlds

in ancient times?

And if so, how do these other-dimensional beings

use them as doorways to connect with humans?

Shapiro thinks it all comes down

to what they're made of.

Joshua Shapiro: The crystal skulls act as

portals or dimensional doors because quartz

crystal has the ability to exist in many different

dimensions simultaneously.

It's the property of the material itself, it just

lends itself to working with energy on different

vibrational frequencies.

So that's why it's a perfect conduit.

Quartz crystal vibrating frequencies across

multiple dimensions?

Crazy talk, right?

Well, in fact, crystals have been used in

communication devices like radios for nearly a century.

They can be tuned to vibrate at specific

frequencies, which allows them to tune in broadcasts.

So maybe a crystal skull could be an

inter-dimensional telephone after all.

Joshua Shapiro: Quartz crystal is, is one of the

most important materials on the planet but to put

it into the shape of a human bone skull, those

two combined make them very special.

So these other intelligences can use

the crystal skull to communicate with us.

So are crystal skulls portals for messages

from other dimensions?

And if so, what are they trying to convey?

Joshua Shapiro: If I could define in one sentence

what the crystal skulls are, they are a mirror

and a catalyst to awaken humanity.

If we as individuals would just be open to all the

amazing phenomena that's going on in our world

instead of trying to rationalize it, I think

that our planet would be at peace much quicker and

we would learn a lot more about ourselves and we

would have additional assistance coming that

we could not even imagine.

Do crystal skulls have the ability to create

electrical signals that allow us to interact

with other dimensions?

Or are they simply harmless hunks of polished rock?

Is there any scientific evidence that gateways to

other worlds even exist at all?

William Shatner: What an incredible story.

Can this skull generate vibrations that allow us

to speak to people in parallel worlds?

Can you imagine what we could achieve if we could

harness the power within this magnificent,

priceless object? Oops.

Can we get another one?

A mysterious crystal skull discovered in Mexico is

believed to be a doorway to another dimension.

Could this be possible?

Dr. Paul Stevenson studies extreme physics at the

University of Surrey.

He thinks the idea of a portal to a distant world

is quite plausible.

Paul Stevenson: One possible way we could at

least theoretically think about opening a door to

another world or a portal to somewhere else comes

from black holes.

Astronomers once believed that everything in a black

hole was crushed into a single point of infinite

mass called a singularity.

But recently, some have proposed another idea.

Paul Stevenson: It's conceivable that you'd

make some kind of portal from one part of the

universe to another that you could actually travel

through and that would be called a wormhole.

And if we can create a sort of tunnel to other

parts of our universe, what does that mean for

parallel dimensions?

Paul Stevenson: Now it may not be a big leap to

suggest that we could create a wormhole that

connects us to different dimensions

or a different universe.

According to Paul, in theory it's possible to

create a pathway to other worlds.

It's nothing anyone has ever seen before so how

does he know it could happen?

Paul Stevenson: But they're actually based on

solid physics and solid science and we've

certainly come across lots of things in the past that

at first sight seem to be utterly ridiculous and

completely fantastical and have turned out to be true.

I don't know whether that's gonna turn out to

be the case for wormholes, whether we'll ever see one

but it's certainly not beyond the bounds of reason.

Could we open cosmic gateways into parallel worlds...

and communicate with them with crystal skulls?

Or can we simply teleport our bodies

there whenever we wish?

Are shadow people from other dimensions

already amongst us?

Weird or what?

So there we have it, stories of parallel worlds

from all over the planet.

In New York, a woman has a terrifying encounter

with a human shaped shadow.

Did it come from another dimension?

In New Jersey, a weird machine transports a boy

and his father hundreds of miles in a split second.

Did they teleport to a different world?

And in Mexico, a team makes an amazing discovery

- a skull made of crystal.

Is it a doorway to a parallel universe?

Are these stories evidence that parallel worlds exist?

Can we dismiss the claims of those

who believe they are true?

You decide.

William Shatner: Join me next time for more stories

that will undoubtedly be weird or what?
