If you saw a wormhole in reality, it would appear round, spherical, a bit like a black hole.

00:08

Light from the other side passes through and gives you a window to a faraway place.

00:13

Once crossed, the other side comes fully into view with your old home now receding into that shimmering spherical window.

00:21

But are wormholes real,

00:23

or are they just magic disguised as physics and maths?

00:27

If they are real, how do they work and where can we find them?

[Kurzgesagt Intro]

00:41

For most of human history,

00:42

we thought space was pretty simple; a big flat stage where the events of the universe unfold.

00:49

Even if you take down the set of planets and stars, there's still something left.

00:54

That empty stage is space and it exists,

00:57

unchanging and eternal.

01:00

Einstein's theory of relativity changed that.

01:03

It says that space and time make up that stage together, and they aren't the same everywhere.

01:10

The things on the stage can affect the stage itself, stretching and warping it.

01:16

If the old stage was like unmoving hardwood, Einstein's stage is more like a waterbed.

01:22

This kind of elastic space can be bent and maybe even torn and patched together, which could make wormholes possible.

01:31

Let's see what that would look like in 2D.

01:33

Our universe is like a big flat sheet, bent in just the right way,

01:38

wormholes could connect two very, very distant spots with a short bridge

01:42

that you could cross almost instantaneously.

01:44

Enabling you to travel the universe even faster than the speed of light.
