Galaxiki Community BlogSubscribe via RSS What if every electron in the universe was all the same exact particle?January 17, 2012by physicsguy http://io9.com/5876966/what-if-every-electron-in-the-universe-was-all-the-same-exact-particle This is an interesting idea many physics undergrads will come across. Based on observations, the central assumption cannot be true, but the insight it brings helped Feynman develop quantum electrodynamics, which in turn aided Hawking in dealing with some of the insanity surrounding black holes. Hawking radiation, in fact, becomes much more intuitive if positrons can be treated as electrons moving backward in time.
