I was rereading one of my physics books where it's explained that the universe is 74% dark energy, 22% dark matter, and 4% regular matter.<br /><br />Now as for the regular matter is concerned it is described as baryonic material which as far as I know consists of mostly protons and neutrons.<br /><br />The Big Bang descriptions describe that initially their was a tremendous amount of matter and antimatter with the tinniest of assymeteries in that their was slightly more matter than antimatter. All of the antimatter is gone when it annihilates with matter leaving a small residue of matter.<br /><br />Now that annihilation process generates a lot of photons which have the same mass as the matter and anitmatter that got annihilated. The mass of those photons should have substantially more mass than the remaining matter.<br /><br />What happened to that mass?<br /><br />Later in the evolution of the universe when things had cooled down to the ponit when atoms formed the photons flying around formed the cosmic background radition. Are those photons drawn from the same mass of photons that came out of the initial annihilation process?<br /><br />Is it possible that the dark matter, at least the hot dark matter is in the form of photons?
