Protons are more massive than electrons, for example, and electrons are way more massive than neutrinos. Photons have no mass at all. For most us, that's no more than a fun fact (and not all that much fun, really). For physicists, though, it's a mystery that demands a solution. Why are the masses so different — and why do any particles have any mass at all? The answer, suggested several scientists back in the 1960's, is that the entire universe is suffused with a sort of energy field — i...
