Is neutrino-antineutrino annihilation something that does actually
happen? I found something that said "Because antineutrinos and
neutrinos are neutral particles it is possible that they are actually
the same particle", in which case you'd assume they couldn't mutually
annihilate, no?
If neutrinos don't have intrinsic (rest) mass, then as well as
no-charge-without-mass, could you also conclude no-mass-without-charge
(at the elementary particle level)?
