Can one quantify the total luminosity of the cosmological horizon?

548 views

If I integrate all the power (radiation, matter particles, neutrinos) radiated from the cosmological horizon into the universe, what number do I get?

Is it true that the integral power/luminosity is of the order of c5/G=3.6⋅10^52 Watt?

And a second question: has the integral horizon power been constant over the past evolution of the universe?
