 Quote by benk99nenm312 Thanks. I assume you meant backwards in time, which is a principal of Quantum Electro-Dynamics. I am not familiar with any notion or theory that disclaims this principal, but it seems that a number of people know about a different way of looking at antimatter. Quantum states of a particle and an antiparticle can be interchanged by applying the charge conjugation (C), parity (P), and time reversal (T) operators. This is the familiar CPT conjugation. Time is clearly a conjugate, so I am confused as to why so many think antimatter travels forwards in time. Maybe it's something I don't know.
Pick up any book on relativistic quantum mechanics and study =)
