I've read some arguments, which claim that an infinitely bouncing universe is not possible. For the sake of argument, let's ignore the fact that our universe is expanding at an ever increasing rate. Instead, I want to focus on whether or not an infinite bouncing universe would violate the Second Law of Thermodynamics. Essentially, the argument boils down to each cycle having an increase in entropy or cosmic radiation determined by previous cycles. However, if each cycle ends in a "big crunch" thereby collapsing back into a singularity, then would not all physical laws break down including the Second Law? Wouldn't this effectively "erase" all information from past cycles?
