I'm sure RGIF isn't a physics group, so no idea how this ended up here
(and I'm unable to see the original post) :-P
But anyway, I agree with Victor. As distance increases, but the amount
of photons stays the same, obviously you're going to observe less photons.
And there's usually some energy loss in individual photons anyway due to
redshift.
