Are there such things as wormholes?

Answer 1

lol... as you can see its hard to give a serious answer - maybe because wormholes have a much more active existence in fiction than in science.

More properly called Einstein-Rosen bridges, wormholes are a theoretical possibility based on incomplete physical theories - general relativity is a superb theory but its incompatible with quantum mechanics - the other big (and superb) theory of the 20th century.

The simple answer has to be that we just don't know. String theory if it receives experimental validation in the next few years may be able to answer the questions in terms of various 'braneworld' scenarios - and indeed if we cannot make use of wormholes there are serious fundamental limits to the success and longevity of the human race! kind regards

Answer 2

Leviathon has the best answer. Wormholes are the stuff scifi is made of...a very little science and a lot of fiction.

Traveling a wormhole, as Brian Greene suggests in his "The Elegant Universe" is very unlikely. First, the forces created by a hole in the fabric of space would be astronomical in the truest sense of the word. No telling what would happen inside one to the hapless body affected by such forces.

Second, the forces required to create a wormhole would also be astronomical. Only the universe itself has the kind of energy needed to create those forces. A singularity force (a scifi favorite), even if it could be controlled, would fall short of the energy needed to bore a hole into the fabric of space.

No, I don't think there are such things. But they do make for good scifi. "Warp two, Scottie."

Answer 3

Yes. You can't see them, but if you reverse the polarity of your deflector array to emit a sub-space pulse, you will see it on sensors.

Make it so.
