Abstract
Massive neutrinos may dominate the universe's rest mass and compose galactic halos. By requiring that the photoionization of the high-velocity clouds of neutral hydrogen near our galaxy not exceed observational limits, we find that the radiative decay lifetime for ionizing photon production by neutrinos ( eV) composing our galactic halo must exceed sec.
