> What if time is a a free variable that can freely move forward and backwards, perhaps doing a random walk? It would have to have some measurable effects, distinguishable from "consistency with states prior to the current t". That consistency with previous states is written as t2=t1+X. If t1+X is always "previous state plus some small change", we simplify X to be 1. If you can invent HOW that random walk would manifest, you're up for a nobel prize.
