Question

Eli5, What’s a wormhole?

In: Earth Science

Answer 1

if space is a piece of paper. fold the paper so the two ends touch. use a pin to poke a hole through both sheets. this would be what we believe a wormhole could be like.

its all theoretical. and we find it hard to imagine space could bend. but supposedly all the math checks out.
