Suppose that a tau neutrino and a tau antineutrino, both of which are just barely moving, encounter each other in space and completely annihilate to form two photons of equal energy. In view of the uncertainty about the mass of the tau neutrino (<18.2 MeV/c2), what is the shortest wavelength lamda0 of light that could be emitted by the annihilation? lamda0 = ? m Would the light be visible to the human eye?
