David Turell: "Why does it go in one direction?"

We perceive time moving only in one direction because energetic reactions, as we understand them and normally perceive them, only occur in positive dimensional space.

Time expressed in negative dimensional space has a reverse direction (negative causality). Positrons have been proven to be electrons that are expressing this negative causality in positive dimensional space.

This of course, is still theoretic.
