Um, OK, but, then ... what is the mass of a neutrino?Ahem, well, I'm sure it's all muscle!Hmmph. How would you feel if I went around discussing the mass of a jennyp?
Exactly! You'll notice that none of the researchers have suggested that neutrinos have any fat mass.
Unless they get into question of flavor...and everyone knows that fat helps transport flavor... (Sigh!)
