the researchers proposed a model in which there are two right-handed neutrino species that have very high masses. The model showed that in the earliest moments of the universe, the left- and right ...

They don’t have an electric charge, have a small mass, and are left-handed (a physics ... So a light signal could overtake the neutrino and it would appear right-handed when viewed in the ...
