What Happened to Wheeler's "Single Electron" Idea??? Hello, I wrote out a lengthy reply that I could not retrieve after I pressed preview and was asked to log in again...not sure if that's a bug/glitch as I am brand new on this website, but it was very annoying ;) Anyways before I introduce my topic I'd like to tell you guys that I have almost no formal background in physics or mathematics....I've used the power of the internet to educate myself as much as possible in modern physics etc so bear with me. I just recently heard of the story involving Richard Feynman and his then professor John Wheeler back in 1940 in which Wheeler calls Feynman on the telephone at some absurd hour of the night and exclaims that "he finally knows why all electrons have the exact same charge and the exact same mass"! If I'm understanding this correctly, he goes on to say that the reason electrons are all perfectly identical is because they are actually just one, single particle moving back and forth through spacetime in a single continuous and connecting world line. The appearance of many identical but separate electrons that we see/experience in our everyday universe is kind of an illusion created by our fixed, sliced view of time. However Wheeler says its really just the exact same particle which has traveled back and forth many times through that particular slice of time. From this idea, he went on to say that the electrons charge is simply its direction in time; so that a positron was really just this very same particle(electron) moving "backwards" in time. Feynman quickly realized the numerous holes in this "theory" but ironically would run with the latter part of Wheeler's idea on his way to winning the Nobel Prize. Apparently the lack of equal amounts of antiparticles and particles in our visible universe is the quickest and easiest way to dismiss this idea but we also hear a lot about broken symmetries and things that could explain this. Basically I'm very interested in finding out what became of Wheeler's idea or theory as physics and our knowledge has progressed.... I personally see some very deep connections and implications if you follow this line of thinking and I just figure there had to be other, much smarter people who took this idea seriously. discuss... Thanks!
