Liz, et al, The problem with your and other's comments is that, as I've explained before, entropy is NOT fundamental as many seem to think..
The current entropy state depends entirely on the current mix of the four fundamental forces, in particular on whether gravitation is more attractive or repulsive. For example if gravitation suddenly switched from attractive to repulsive from a universal black hole collapse to a white hole big bang that would automatically explain the supposedly improbably initial LOW entropy state that has Penrose and others so puzzled. So when you try to connect information and entropy you again run into this same problem. If, as the universe expands, the balance of repulsive to attractive gravitation shifts so will the entropy balance. This is easy to see. In a universe where gravitation is massively repulsive the maximum entropy state will be a uniform dispersion of matter throughout all space, but just the opposite in a universe with massively attractive gravitation where the maximum entropy state will be a single universal black hole. So entropy is NOT fundamental. It depends on the current mix of forces. AND entropy has nothing to do with the arrow of time either.
