Query: Super-Kamiokande 0.07 eV Neutrinos in Cosmology: Hot Dark Matter and the
  Highest Energy Cosmic Rays   Relic neutrinos with mass in the range indicated by Super-Kamiokande results
if neutrino masses are hierarchial (about 0.07 eV) are many times deemed too
light to be cosmologically relevant. Here we remark that these neutrinos may
significantly contribute to the dark matter of the Universe (with a large
lepton asymmetry $L$) and that their existence might be revealed by the
spectrum of ultra high energy cosmic rays (maybe even in the absence of a large
$L$).
