So, what happens when black holes collide, and merge into a single one? Serious question, btw - would we experience it, or does our universe contain all matter to ever enter our black hole, therefore all it has merged with?
If the latter, how big can black holes get? Can they consume a universe? That would be a neat end-result - the whole universe goes down the drain, to cause a new one.
Our Universe has disproportion between (visible) matter and antimatter. Black holes my contain missed anti-matter. So when black hole will consume all matter of our Universe, it will bang again, without help of any parent Universe.
I said "other 'side'", not 'other side'! (dimensions are silly :) )
However, I'm not a physicist and really have no idea what I'm talking about :( reading about cosmology is only a hobby/daydream of mine.
