BTW, time-traveling sub-atomic particles are pretty much accepted as a component of reality by mainstream physicists. The arrow of time doesn't have much meaning on the quantum level. Richard Feynman wrote extensively about their effects. Some even believe that anti-matter is simply ordinary matter traveling backwards in time. According to that hypothesis, the annihilation that occurs when a particle of matter meets a particle of anti-matter is simply one and the same particle making a u-turn in time.
