Where do black holes come out? Is that a silly question? Are black holes synonymous with wormholes? What is the connection of black holes with white holes, if those in fact exist?
Lets back up. I'm not sure that a black hole isn't anything more than an abyss of despair but we'll give this a shot. A black hole is an infinitely dense point in space. Anything can become a black hole if you were to magically shrink everyday matter down small enough. When matter is small enough and when it's sufficiently dense it can create enough gravity to suck in everything around it such that nothing can escape it, even light. Black holes are usually formed from collapsing stars and can range in size. There are even theories of mini black holes, which are black holes set on an atomic scale. These are said to be the size of an atom but have tons and tons of mass. Freaky, huh?
So we can detect black holes and we know they exist through careful observation. Where do wormholes come in? A wormhole is generally defined as a bridge that links two points in space that could theoretically allow one to travel faster than the speed of light. Currently there is no evidence for wormholes, but there is also no evidence to disprove them either. So personally I think it's highly likely that it's all a bunch of nonsensical fiddle faddle. Anyway... these would form in the center of a collapsing galaxy so nothing would be able to survive the crushing gravity that has to be involved with the wormhole. I guess it really wouldn't matter if they exist because we'll never be able to even approach the event horizon of one because we would be ripped to shreds by the awesome gravity.
White holes are supposed to be the opposite of black holes. Go figure. In black holes matter and electromagnetic radiation are sucked in and presumably in white holes these things are spewed out. Where does all of this energy come from? I guess the idea is that a white hole is the time reversal of a black hole and it is a point mass that repels matter instead of attracting it. Some people, namely my brother, seem to think that white holes are somehow connected to black holes and everything that is sucked into a black hole is blown out of a corresponding white hole. I'm not sure this would work just because they are two separate point masses. But we don't know anything about white holes, they've never been observed, and the only reason the theory is around is because it solves some obscure equation that has something to do with worm holes (which we also don't know exist).
Could there be a theory to connect these black holes, white holes, and wormholes? Think a-bout, man! As long as we're entertaining mad science we could postulate that matter and energy are crushed down and ripped to shreds by the black hole, transported by the wormhole to the white hole, where it is all jettisoned out back into space. Well why not, right?
So to answer one of my original questions: yes, that is a silly question.
I still have a lot to think about.
