The existence or non-existence of temporality in our universe is a very, very deep and fundamental question. The respected physicist Carlo Rovelli has spent a lifetime working on the problem. Your comments that energy spreading requires time does not answer the "which came first the chicken or the egg" question? Does "spreading" occur over fundamental (T)ime that exists or does "spreading" create a derived (t)ime over which it is measured? The answer to that question determines if we live in an atemporal universe or not. Please visit www.ws5.com/spacetime for a lengthy discussion and links.
