According to LQC, did the universe before the bounce contain black holes? If so, would they still be around? What I'm getting at is this: I've read that LQC predicts that the high densities around the bounce tend to smooth out inhomogeneities. If I understand correctly, this is quite promising because it explains the (near) homogeneity of the early universe, and thus the Second Law of Thermodynamics (according to Penrose in "The Emperor's New Mind"). But what about entropy & information during the bounce itself? If there was nothing special-a macrostate with very many microstates- going in, doesn't conservation of information imply that all that entropy should still be present in our universe? I don't know much even about thermodynamics, & certainly not about BtSM science. That's why I'd like an answer that addresses black holes specifically- hopefully that will be concrete enough for me to think meaningfully about. I'm using black holes as a specific instance of high entropy, because I take from Penrose that they would represent the major component of the entropy in a collapsing universe.
