I wish Physicist would show up. My understanding regarding various theories of so-called "Oscillating Universes" is that they're supposed to undergo an entropy increase each time they bounce, so it can't be an eternal cycle. (I have my doubts about that.)

So do I, because like you, I have my doubts that entropy continues to increase with each bounce.

... like you, I have my doubts that entropy continues to increase with each bounce.

I've read -- this is 2nd hand only -- that back in the 1930s, someone named Tolman showed that entropy increase was inevitable for a continuously oscillating universe. The reason I'm dubious is that I don't know where the "lost" energy/information would go. It's all got to be preserved in a crunch for yet another performance of the cosmic show. Or so it seems to me.
