FOR this?.....changing flavors. The sun should output more electron neutrinos than are detected. The theory is that they occilate into different flavors of the the neutrino...like the tao and muon neutrino. They cannot do this if they didn't have at least a tiny amount of mass.
Neutrinos have mass. In multiples of the proton mass the Electron-neutrino has mass < 10 to the minus 8 power, the Muon-neutrino has mass of .0003 and the Tau-neutrino has mass of .033.
Re: Re: Do nutrinos have mass? Why not? By who? Do you have a source to support this statement? See the above question.

And here are a few more references on the subject of neutrino mass. It seems to be well established that neutrinos have mass. http://www.eurekalert.org/pub_releases/1998-06/UoH-MAOD-050698.php http://focus.aps.org/story/v2/st10
neutrinos having mass is a well accepted fact now. i havent checked those links but since i have met/been taught by professors who were involved in the experiments i tend to believe the work and the papers.
