Could 'Dark Matter' be Nutrinoes?

  1. Aug 18, 2010 #1
    I was thinking about this and simply dont know enough about it all to answer my own question so was hoping someone could help me, is it possible that the dark matter we are searching so hard for are actually Nutrinoes, since they do indeed have mass, with their sheer numbers could it explain for some of the things attributed to dark matter?

    It used to be thought that this was a possibility, but these days we are pretty sure dark matter is not neutrinos. That is to say, dark matter is composed primarily of something other than neutrinos. This is because they don't have enough mass, and because they are moving around too fast to collapse into the structures that we observe.

    Sterile neutrinos are still a possibility for dark matter, as far as I know, but they're just as exotic as any other possibility, in my opinion.
