First and foremost, I would like to say that I have no actual training in astronomy or cosmology, so bear with me as I'm pretty much just a hobby reader in both fields. A few days ago, I think I read something here along the lines of the possibility of new universes being created (hypothetically) via black-holes; the extremely dense point at the 'bottom' of a black-hole tunnels through space-time and then, through some sort of quantum fluctuation, expands in a much similar way to the Big Bang that our own universe experienced. My question relates to the size of this hypothetical new universe; would the size of it not depend on the amount of material that the black-hole originally sucked from its own surroundings? My apologies if the answer is blatantly obvious or it has been answered a million times before - it's just something that's been puzzling me for a while. Thanks for any information!
