" ... A logarithmic scale showing the masses of the Standard Model's fermions: the quarks and leptons.... [+] Note the tininess of the neutrino masses. With the latest KATRIN results, the electron neutrino is less than 1 eV in mass, while from data from the early Universe, the sum of all three neutrino masses can be no greater than 0.17 eV. These are our best upper limits for neutrino mass. ... "
