Neutrinos: the Real Nature of Dark Matter After All?
  What exactly is Dark Matter? New theories for what really constitutes Dark Matter appear to make the news headlines every week. At a slower pace, these theories are slowly being eliminated. We revisit this scientific thriller and make the case that condensed neutrino matter is a leading suspect. We provide a forensic discussion of some subtle evidence and show that independent experimental results due out in 2019 from the KATRIN experiment will either be the definitive result or eliminate condensed neutrinos as a Dark Matter candidate.
