The prize went to two researchers that confirmed that neutrinos have mass, or can have mass depending on how they are feeling at any particular moment…
The question is, could this be connected in any way to the mystery of “Dark Matter”?
Not really, neutrinos can only be considered as hot dark matter, which is insufficent to explain dark matter completely. So while neutrinos may likely make up some part of dark matter, the gravitational effects of massive neutrinos would still be much smaller than the parts we don’t know about yet.
