Hi.
I've recently be researching online about worm holes. At least I tried, because I could not find a lot of matching information. most the time I can only find the vague description of a theory.
I would like to learn more about how worm holes appear, and what theory about their activities are.

well accually this is more about time travel but it has to do with worm holes
Is going back in time really possible? If so, would we have the resources to do it..say 100 years from now?
It may be, it may not be. The laws of physics that we know about don't seem to forbid it. The easiest way to do it would be with a worm-hole, a sort of "short cut" from one part of the universe to another. There are ways (in principle) of creating a worm-hole with one mouth in the present and one mouth in the past, so that if you went through it, you would be travelling back into the past. There are reasons to believe, however, that such a wormhole would be unstable. The matter is still very undecided. In any case, you would not be able to go back and change recorded history, since everything you do in the past must be consistent with the state of things in the future. Nor could anyone come back from the future to the present period, because you can only go as far back, using this method, as when the wormhole is first created. We also would not have this technology (if it is possible at all) for many thousands of years, I'm sure.

What would it mean by "unstable" how so? I mean worm holes seem like the only way we can successfully explore the universe in a fairly reasonable amount of time

I believe what I have out of a black hole is that a black hole is when a star collapses, or rather loses all its fuel and takes in other outside energy to feul it. The star expands to try to take in more. Please do correct me if im wrong. Thats about what i got from my astronomy class.
