Dark matter is most likely the graviton flux that has been emanating from mass-energy since the big bang. It is literally the gravitational field itself. Gravitons are likely negative mass particles - this makes sense considering the zero total energy universe conjecture lauded by Hawking, Krauss, and others.
Interesting, can you point to a paper outlining this theory and how it matches all of the extensive observations that otherwise have supported the theory of dark matter?
