Matter curves space time . as its mass grows the curvature of space-time grows. This curvature procedure of space time is to my opinion what slows down and prevents from mass to reach the speed of light. the bigger the mass the slower it goes with the same kinetic energy. Based on this logic ,since light always travels at the speed of light, I assume that it doesn't curve space time ( I am referring to photons travelling in open space time and not in a box where photons and matter interact). since Gamma rays can produce matter and anti-matter pairs .Since I assume that photons do not curve space-time ,but matter does ,then in order to conserve the original photonic anti-gravitational behavior, its anti-matter pair should have neutralizing anti-gravitational behavior. So if matter "pulls" towards it and slows time ,anti-matter "pushes" away from it and makes time run faster .this can explain why we cant see anti matter ,since it is spread in space stretching it in contrast to the matters gravitational pull. this can also explain the source of the "dark energy" . This theory can be tested on anti-matter particles and photons in the future. what do you think?
I know that the question if photons apply gravity was asked before and that there is not enough data today to answer this question and we are all based on General Relativity equations. what I am asking is ,assuming that photons in free space do not apply gravity, can we predict based on the fact that a Gamma photon can generate matter and anti-matter pairs that anti-matter applies anti gravity in order to keep the neutralizing zero gravity of the photon? this in my opinion is not a duplicate question.
