Main Question or Discussion Point
I've racked my brain over this one since I was 15 and I really can't figure it out. I can see how two electrons would bounce away from each other with the exchange of a virtual photon, since one pushes off on the photon and the other absorbs it(even if I don't understand how the electron knows when to shoot out the photon, in which direction and where it goes when it's absorbed). But how a positron and an electron can attract with the same kind of exchange is completely beyond me. Is this just the kinda weirdness that goes on at those levels?
