Greatly enjoying this thread. BTW, my belief is that time is an artefact of our biological endowment: because we remember events in the same order as that in which entropy in the Universe increases (can't be otherwise: the biochemical agency of memory releases heat and increases entropy) we falsely believe the past has already happened and the future has not. Reality is just one thing and it is as it is, was and shall be. Our minds created time.
We don't need to predict that time effects rays of light, we can time the suckers..... Anyways, time is a measure of change, not effect. Time effects nothing, it's just a way of describing the effects of other precesses. As for aging, wellllll..... Relativity would make more sense to me if I was not a retard, and if I knew something about physics, I guess....
