Take a piece of paper, fold it over and carefully push a pencil through the paper so that it comes out the other side.
Congratulations, you've just demonstrated what a wormhole is.
If you can imagine space as being the paper, by folding it over, you've created a much shorter distance to travel.
And you can fold space by just being heavy and the pencil is the wormhole generator.
Let's do it
Some scientists reckon a real wormhole generator would have to be the size of a city to open a human-sized wormhole.
But sub-atomic particles may by heavy enough to open tiny wormholes called Quantum Foam.
If we can turn ourselves into an electrical signal (see teleporting), it might be possible to 'beam' through the foam and out the other end.
