A worm-what?

A wormhole is like a tunnel, connecting two parts of the universe.

A tunnel of sorts.

Traversable space as we know it, is three dimensional. So, the wormhole would actually look like a sphere, and not a flat 2D hole.

A spherical tunnel.

A comparison perhaps?

Getting from point A to B, really fast, in a place we can't see in the day to day.

Space travel is so real, oh my god.

Q: How are they even made? Do they just appear?

Q: What do they look like? What will I see if I peer inside?

Q: Can a human or any living thing on Earth survive the journey through it?

Q: Can you travel faster than light in a wormhole?

Q: What about time inside a wormhole?

Wait, what about time-travel?

Q: Can you travel back in time with a wormhole?

Q: Can you make wormholes?

Such an Einstein thing to do....

"Determines that the law of physics are the same for all non-accelerating observers and that the speed of light in a vacuum was independent of the motion of all observers."

- Theory of Special Relativity

Oh Einstein.

But there must be more!

These famous physicists wanted to introduce acceleration to the mix.

Albert Einstein & Nathan Rosen.

Massive objects cause a distortion in space-time thanks to gravity. The bridge should do the same!

The Einstein-Rosen Bridge

What a weird name for a bridge!

German mathematician Hermann Weyl, analyzed mass in terms of energy of the electromagnetic field. 

1921. Hermann Weyl.

Theoretical physicist John Wheeler introduced the term ‘wormhole’ inspired by the Einstein-Rosen research.

The word comes from a worm boring a hole through an apple.

He imagined mass being threaded by electromagnetic fields.

1957. John Wheeler.

Okay, okay, slow down.

Q: How are they even made? Do they just appear?

We have no idea. There is no empirical evidence as of yet, to prove it existence, to even begin observing the lifecycle of a wormhole.

There are many theories presented about the existence of the wormhole based off of relativity.

We don't know.

Some theorize they form and disappear within fractions of seconds, so fast that even light could not have gotten through.

Almost Un-noticeable.

Stuff they needed to hold a wormhole open violates the weak energy condition; negative energy cannot exist according to our understanding.

Traversable wormholes are hard.

Exotic matter was made in tiny amounts between electric plates; the Casimir effect.

Negative energy does exist!

Q: What do they look like? What will I see if I peer inside?

Unsure. Kip S. Thorne has relative confidence in his idea, that it's sort of ...

Distorted image based on what we know about physics & light on earth. All speculation though.

Like looking through a lens.

We're unsure. The forces in the wormhole are theorized to be extreme in nature.

Q: Can a human or any living thing on Earth survive the journey through it?

Physicists tried to find a different wormhole than in Einstein's, one where you can travel through, called a Transverse Wormhole.

It would need "Negative Matter" or "Exotic Matter" to keep the hole open long

enough for one to travel through.

Better question, can we ever?

Q: Can you travel faster than light in a wormhole?

No you can't, because the universal speed limit is the speed of light. You might seem to travel faster than light, relatively.

Q: What about time inside a wormhole?

Time would be warped inside. Relativity says time would be extremely slow in the reference frame of the traveller, while time outside goes faster.

Space-warping was infact observed from signals to Viking 1 & 2, near Mars.

Time is warped. Space should be warped too!

Einstein’s theory of relativity states that it is impossible to accelerate anything from rest to some velocity faster than light.

Remember Relativity?

Not really. Time can bend & warp, but not go backwards.

Q: Can you travel back in time with a wormhole?

This device can transmit the magnetic field from one point in space to another, through a path that is magnetically invisible. ​

On making wormholes...

At the moment, we can't. We might get there though.

Q: Can you make wormholes?

What does the future hold ?

These strange phenomena were also theorized by Einstein to exist.

They have been found. So we have hope.

Black holes are real. Real.

Gravitational waves are real.

LIGO or the Laser Interferometer Gravitational Wave Observatory has detected and proved their existence through two separate events.

An ultra-advanced civilization is my only serious hope for making traversable wormholes. But it would face huge obstacles, so I'm pessimistic."

- Kip S. Thorne, theoretical physicist

The future is exciting.
