In every documentary I've seen about worm holes, I have noticed that they usually say that according to the General Theory of Relativity, there could exist worm holes called traversable wormholes; these are stable worm holes and travelling through them is possible. In that case they can be used to travel in time, and Inter-Universe travel may also be possible. One can also find some of the above statements in Wikipedia.
Now my questions are the following:
Is travelling through a worm hole really possible (if we can find a stable worm hole)?
The reason for the question is: according to the same general theory of relativity which gives them the traversable worm whole with exotic matter, worm holes have a similar metric to black holes. As we go close to a black hole the gravitational pull at one point of our body (or a spaceship or probe's body) is different from the gravitational pull at some other point of our body (or a spaceship or probe's body) which will lead to a severe stress and our body (or a spaceship or probe's body) will be broken into pieces. This should also be the case for a worm hole, I guess. Worm holes are a particular kind of space-time distortion or a field of gravitation, similarly to black holes, so can any man-made instrument or craft survive the trip through a region of severely in-homogeneous gravitational field?
If the answer of Q1. is "no", then I would also like to know
- i. Why is such a thing shown in scientific documentaries narrated by world-widely popular scientists? ii. Are those documentaries not misleading their audiences?
I also have a separate question,
- If there is a worm hole, will it not attract nearby objects? or don't worm holes exert gravitational attraction?
