   If I recall correctly, not long ago Steve Carlip pointed out here that   
   positive mass attracts everything, including negative mass, and negative   
   mass repels everything.

   This is then independent of whether negative-mass antimatter previously   
   annihilated.

   Neutrinos cannot be cold dark matter, because a) they are not cold and   
   b) their mass is not large enough.  You have to postulate some sort of   
   "neutrino" beyond the standard model.

   That is a separate question.

   Why not?

   Neutrinos/antineutrinos do not move at speed c.
