Well the thing is: it’s even worse! We HAVE measured ‘the’ neutrino mass, sort of (not really). We have an absolutely fricking tiny upper bound! For all three masses added together… And yes, there are three separate neutrino masses just like there are sorta three ‘types’ of Neutrinos. But the real kicker is: it is literally impossible to assign any specific mass to any specific type!!

You can either talk about the type of a neutrino OR it’s mass but not both at the same time because apparently we looked too close and quantum mechanics decided it needed to fuck with us some more to discourage further probing.
