I understand the resolution to the typical statement of Olber's paradox, that is, that with a finite horizon distance only light up to a certain distance will have reached Earth. However, let's say that we modify the contents of the universe such that we have an infinite horizon distance. Why, in this case, do we still have a finite brightness? I think it is that because with red shift the wavelength is being shifted and by the time the light that propagated past a certain distance will have red shifted to wavelengths we no longer detect as light. Is there a better resolution? Thanks!
