I was just reading a little about the neutrino and noted somethiing interesting. 1) neutrinos travel at close to c 2) neutrinos have a small amount of mass. So how do we justify that the mass of the neutrino does not seem to be approaching infinite. I'm gonna have to find the equation but doesn't it state that as v approaches c the closer to infinite mass becomes? If a neutrino does have mass and suddenly jumped to c[I/] would there be a massive increase of ..er.. mass? I know there's probably an expl. but I don't gitit.
