    Just more "I watched a Youtube and now I'm an expert" nonsense.

    Yes, just reading From eternity to here again, and Sean Carroll explains, that the final crunch from a contraction, would not be as clean as the emergent big bang, because all the mess that the universe has accumulated during its life, going and coming, black holes et al would be all present into the final fall, and really cause havoc.

    Which is what really put me off Poul Anderson's Tau Zero. You can't orbit the Big Crunch at a safe distance so as not to get crunched!

    It is small comfort when you are that close to the end to know you going to get crunched by a clean anti-BB squeeze or a messy, large entropy cauldron.
