I told you; I just want to estimate the total energy of the observable universe, at any time t. I am not dealing with any conservation law, although I grant you raise an interesting issue. Moreover, I think the photons can be considered among the 10^80 particles, but clearly those photons have energy h * f, and I assume we can assign some average frequency to estimate the total contribution from those photons.
