Events in our universe are causal consequence of each other. Most recent event A is simply the consequence of less recent event B, which in turn is the consequence of another event C and so on. They are NOT consequences of time, but only of each other.

Therefore, "reversal of time" and "time travel" are logical nonsenses. You can not have the event A which is a CONSEQUENCE of event B if there is no event B - and this is what happens when you try to "reverse" time.

Basicly, there is no such "thing" as time, there are events following from each other. Not following each other, but FROM each other.

Thus no time reversal/travel is allowed (by what we call causality - events originating from each other).
