Why is the night sky dark?
Assume we have an infinite grid of stars spaced evenly and we are not in one of them
The brightness (and tidal forces) we get is ∑∑∑1/((i-1/2)^2+(j-1/2)^2+(k-1/2)^2)
The question is,does this converge?
If we slightly tweak our model a bit,so that the universe on a polar coordinate,and the stars form a circular pattern,and the nth layer has n stars on it,we get an harmonic series of light which is unending and still less than the 3d universe.
Call Hubble to the rescue!
