If the Universe is infinite and uniform (Condition #1) and not expanding

the sky is generating the light, if it has been generating that light for an
infinite time from infinite points in space, then the resulting light must
be infinite. Since the sky is dark at night, the Universe cannot be infinite
and uniform unless the proponent offers a different solution to the Paradox.

OTOH, if an infinite non-expanding universe had a roughly uniform finite
energy density at one point in time, it would be rather surprising if it
came to have an infinite energy density at some future time. Therefore
Olbers Paradox tells us next to nothing about the real universe except
that somewhere in it someone did the sums wrong. :-)

Talking about infinities is a sure way to lead to mistakes, and I'm
probably going to make one, but why should the light be infinite? Won't
it be the same as the surface of a star over the whole sky?
BTW, Charlier's cosmology apparently leads to an infinite static
universe which does not suffer Olber's paradox.
