If you saw a wormhole in reality, it would appear round, spherical, a bit like a black hole.
Light from the other side passes through and gives you a window to a faraway place.
Once crossed, the other side comes fully into view with your old home now receding into that shimmering spherical window.
But are wormholes real,
or are they just magic disguised as physics and maths?
If they are real, how do they work and where can we find them?
[Kurzgesagt Intro]
For most of human history,
we thought space was pretty simple; a big flat stage where the events of the universe unfold.
Even if you take down the set of planets and stars, there's still something left.
That empty stage is space and it exists,
unchanging and eternal.
Einstein's theory of relativity changed that.
It says that space and time make up that stage together, and they aren't the same everywhere.
The things on the stage can affect the stage itself, stretching and warping it.
If the old stage was like unmoving hardwood, Einstein's stage is more like a waterbed.
This kind of elastic space can be bent and maybe even torn and patched together, which could make wormholes possible.
Let's see what that would look like in 2D.
Our universe is like a big flat sheet, bent in just the right way,
wormholes could connect two very, very distant spots with a short bridge
that you could cross almost instantaneously.
Enabling you to travel the universe even faster than the speed of light.
