caharris Posted October 16, 2010 Share Posted October 16, 2010 A friend asked me a question that I didn't know the answer to, so I thought I'd ask you all. "What if dark matter is the product of matter-antimatter interaction in the early universe?" Any information would be appreciated. Link to comment Share on other sites More sharing options...
Mr Skeptic Posted October 16, 2010 Share Posted October 16, 2010 I think we would have noticed that, by adding up the momentum of the photons released when matter/antimatter collide. That's how we found the neutrino (for neutron decay). Link to comment Share on other sites More sharing options...
