Read up on Richard Feynman's Transactional Interpretation of Quantum Mechanics. Its basically a more understandable treatment of Dirac's original work. Feynman once made the interesting observation that a particle and its anti-particle seem to behave the same if you look at them as moving in opposite directions in time. John Clark's description of two reactions a few days ago shows how you can see this in such a simple reaction.
