Hey guys, I was just pondering the idea of dark matter and a thought crossed my mind. I may be entirely off, but a few connections can be made between gravitons and dark matter. Neither can be detected directly with any classical methods (EM, pressure, etc..), and dark matter has no apparent "mass", for its mass is attributed to the excess of gravitational force in galaxies. Perhaps free-floating gravitons that are concentrated around galaxies and are undetectable a possible suspect for dark matter? I know that, theoretically, gravitons are supposed to be contained in hadrons, but perhaps a large amount of them were not bonded with matter during the big bang? Is this even possible?
