Universe of a single electron

In the one-electron universe hypothesis popularized by Richard Feynman in his acceptance speech for the 1965 Nobel Prize for Physics, it is postulated that the universe contains only one electron. This electron would propagate through time and space in such a way that it would appear to be in multiple positions simultaneously. Description

Through a phone call in the spring of 1940, John Wheeler, director of Feynman's thesis, proposed the hypothesis. Wheeler claimed to have found an elegant explanation of the mechanical-quantum indistinguishability of electrons. One day, Professor Wheeler called me at the Princeton Doctoral Institute and said, "Feynman, I know why all electrons have the same charge and mass." "Why?". "Because they are all the same electron." And then he explained to me: "Suppose the lines of the universe we have been considering assume that instead of advancing in time they were really an immense knot." If we cut the knot in a plane corresponding to a particular instant, we would see many lines of universe corresponding to as many electrons, except for one thing: if we take the universe line of an ordinary electron, in the section where it has turned and comes to us from the future, we have the wrong sign for time own-for the four own speeds-and that is equivalent to changing the sign of the charge.Therefore, in that part of the trajectory would act as a positron. "But, Professor," I said, "there are not as many positrons as electrons." "Well, maybe they're hiding in the protons, or something," Wheeler replied.
