I just read an article from the KATRIN experiment in 2019 that they had the mass of the neutrino down to 1.1 ev. They were trying to pin the mass even lower than that? I have not seen any articles saying they succeeded.
Cosmological measurements suggests that the mass should be no more than .1 ev. The WIKI page states that it is .120 ev. Who's experiments (if any) have verified this mas?
