Some Uses of Neutrino Telescopes

Abstract

We imagine that large neutrino telescopes will be built and that distant neutrino sources of high energies and fluxes exist. Some possible, if difficult, uses to which they might be put are described; including (i) detecting neutrino mass-mixing possibly upto delta m^2 of 10^{-16}eV^2; (ii) measuring neutrino cross-sections at PeV energies; (iii) detecting relic neutrinos; (iv) doing cosmology with neutrinos and (v) SETI with neutrinos.
