I read somewhere here (IIRC, I tried to search it but the search didn't work for some reason) that light intensity at astronomical distances stops falling off at the expected rate (I think it would be inverse squared combined with the redshift etc.)

 

If I didn't dream this does anyone have an explanation or link?

I may be totally off but since none has answered, I remember this thread by Martin:
