Neutrinos: the Real Nature of Dark Matter After All?

TL;DR

This paper explores the hypothesis that condensed neutrino matter could be the true nature of dark matter, analyzing evidence and upcoming experimental results to evaluate this possibility.

Contribution

It revisits the neutrino dark matter hypothesis and discusses how recent and upcoming experiments could confirm or refute it.

Findings

Preliminary evidence supports neutrino matter as dark matter candidate.

Upcoming KATRIN experiment results will be decisive.

The paper provides a forensic analysis of subtle supporting evidence.

Abstract

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.
