if the universe is infinite in size, the distance between us and any galaxy will still not be infinite.

If the distance between us and any galaxy is not infinite then clearly the universe is not infinite in size.

Err, not exactly. A universe being infinite in size doesn't preclude two things from being next to each other.

re: photon energy: true. The background actualy -cooling- probably precludes an infinite universe; it'd have to be either constant or increasing (unless all the non-visible stars are pulsing at the same time, but that is er, not likely).
