Time Reversal Need Memory

summary:

Time reversal requires memories of where something was, so it can be undone.

description:

The look of time reversal is familiar. It requires a linear sequence of ordered events to be played back in exactly the reverse order. Time represents the real numbers, a totally ordered set. This set property grants the ability to run things backwards.
