Galactic Dark Matter Population as the Source of Neutrino Masses
  We propose that neutrino masses can be zero $in ~vacuo$ and may be generated
by the local distribution of dark matter through a feeble long range scalar
force. We discuss potential phenomenological constraints and implications of
this framework. Our model typically implies that the relic neutrino background
left over from the Big Bang is mostly absent in our Galactic neighborhood.
Hence, a positive detection signal from future proposed experiments, such as
PTOLEMY, could in principle falsify our scenario.
