Extended Text:

Neutrinos have mass but only a little, and nobody knows exactly how much. Of the three flavors of neutrino (electron neutrino, muon neutrino, tau neutrino), the heaviest has at least one 10‑millionth the electron's mass and could have more than 10 times that much. But which flavor is the heaviest? That too is uncertain.
