http://en.wikipedia.org/wiki/White_hole I didnt know there was such a term until now. Whats your opinion on it?
Nice thought experiment, ... that Black Holes have a singularity at their centre, and the Universe was created from a singularity, so black holes in our Universe start other Universes, and spew out matter, ... But, there's no way to tell, as physics breaks down at a singularity. Cool idea though, kinda Fractal Universe and all that, all plumbed together via black holes.
A white hole is speculation unlikely to be close to reality. BTW: The notion of black holes in one universe spewing out matter to create another universe is nonsense. No black hole in our universe contains enough matter to populate a small galaxy.
Nothing like a white hole has ever been observed. And there are a number of theoretical problems with singularities not hidden behind an event horizon. Many physicists suspect that "naked" singularities cannot exist.
For them to exist you must make them. most black holes probably is some particle mess. Now if all them became black holes too... Then perhaps perhaps not.
