I agree with Jason. Natures processes are simple. 'Physics' is complex because we're confused, clinging on the flawed ideas. Re; entropy. Our view is a parochial 'snapshot' in time. Consider; ALL those things which can only fall apart in out belief STARTED OFF 'apart', as the most fundamental particles! Time didn't 'reverse' for them to form, that's naïve. Consider nucleosynthesis. It's the polar opposite to the entropy we see now! Cyclic universe models are proving far more consistent that the old one most still cling to; The 'Big Bounce', Penrose, Turok etc, and most consistent of all the 'Discrete Field Model' (DFM) which reproduces all CMB peculiar anisotropies and seems able to unite SR,GR and QM in a simpler model. In that model w entropy and expansion are just PARTS of a coherent cycle, free of inconsistencies.
At ALL times in history 'doctrine' has proved wrong. it's still inconsistent now, why do we think it's suddenly right now and cling onto it?
