When you look at the night sky, it is mostly black, so there don't seem to be as many photons around as would be needed to account for dark matter (or dark energy for that matter ;). Of course, I could be wrong, but that's my first impression. Regards, Robin van Spaandonk local asymmetry = temporary success
