Abstract

Recent observations of the dwarf galaxy DDO 154 provide an unambiguous lower limit on the mass of the neutrino: If neutrinos are the "missing mass" of this galactic halo, then m>94 eV. For 1, this requires that H0>99 km s-1 Mpc-1 and that the age of the Universe is smaller than 6.7 Gyr. This is smaller than the age of globular clusters and white dwarfs and contradicts all estimates of the age of our Galaxy based on nuclear cosmochronology.
