Chronos said:Does causal disconnection insulate 'baby' universes from the fate of 'mommy'?
As I understand the model, yes; the baby universe, like any event inside the event horizon of the black hole that spawned it, is causally disconnected from events in the exterior region in the original universe, including "heat death" or anything else. The only caveat to this that I'm aware of is that the "baby universe" model, AFAIK, doesn't work if the original universe recollapses in a Big Crunch, because in that scenario there are no true event horizons in the original universe; every timelike or null path ends up in the Big Crunch singularity, so there is no "room" for baby universes to spawn, so to speak. But this is getting outside of my comfort zone too; I don't know what other kinds of speculative models have been considered, so there may be some that get around this somehow.
