I know little about this but supposedly there is some thinking coming from LQG that black holes might be new universes and that our own universe may itself be a black hole birthed from another. Black holes are constantly both gaining and losing energy. Assuming our universe is a black hole (which of course is assuming quite a lot) I wonder if this gain and loss of energy could somehow be observed from our perspective, maybe as something like the effects of dark energy say. Has this been at all discussed or is there some obvious answer? Any information, ideas, or comments?
