Is it possible that in the beginning there was one photon that split and resplit over and over until the present day and that all photons are entangled?I will up the bet.
Since photons travel at the speed of light time is slowed to zzzzzzzzzzzzero in the reference frame of the photon. As a result, photons don't have to concern themselves with time and they can be everywhere at once.
So you only need ONE PHOTON to populate the universe.
That is indeed an alternative way to state the problem. I don't know at this time which approach yields the quicker solution or the simpler formulation.
