Question: Is it possible for humans to travel through wormholes once it's deemed real?

Miriam Hogg answered on 8 Nov 2018:

If wormholes are real I don’t think we would be able to travel through them.

The current theory is that black holes are infinitely dense and warp spacetime around them. Some believe that two black holes may ‘meet’ and fold spacetime into a wormhole where the two are linked, and therefore are linking two different parts of space.

However black holes are so dense that no even light can escape once they have gotten to the ‘event horizon’. If both sides of the worm hole are black holes there is no escape. There is another theory that the other end of a black hole is a white hole where the matter that was pulled into the black hole is expelled. If these types of wormholes exist the travellers would have to enter the black hole and emerge from the white hole (so it would be a one way trip). However most believe that entering black hole would be deadly as they are so dense they would destroy our bodies.

There are also problems with making a stable wormhole in these situations and most theories would require ‘exotic’ particles to stabilise (where ‘exotic’ means nothing like what already exists and is beyond what we understand in physics).

I hope that answers your question well enough 🙂
