When looking at the energy count in the Universe, on one hand we are told dark energy 68%, dark matter 27%, regular matter 5%, neutrinos and photons a very small fraction (trace like). https://en.wikipedia.org/wiki/Dark_energy
On the other hand we are told, when regarding matter- antimatter imbalance that in the early Universe there was ~ 10 billion antimatter particles for 10 billion +1 matter particles. The 10 billion annihilated together and the matter particle remained.
Since this annihilation produces photons, should there not be about 10 billion (x2) times more energy in the form of photons than in the form of regular matter?
The loss of energy by photons due to expansion does not account for the difference between these two results, does it?
What is the explanation for the apparent discrepancy?
