M/R is a constant in E=(M/R) mg. The energy of mass,m, at the event horizon of any M( black body /black hole) is E=(0.67358*10^30 kg/km)*m(6.672*10^-20 km^3/kg sec^2) which is E=1/2 mc^2 and renders a boundry condition as the maximum gravitational energy a black body mass,m,can attain at the event horizon of a black body,M. From this the graviton energy is determined from a proton at the event horizon where the graviton energy is 1/2 the rest mass energy of the proton.
