http://en.wikipedia.org/wiki/Angular_size_redshift_relation the Wiki entry for this declares itself a stub What they have is just a few sentences serving as a place-holder until somebody contributes a real article. the thing about angular-size redshift relation is that out beyond a certain distance (z about 1.6) things LOOK BIGGER THE FARTHER AWAY THEY ARE. We talked about this some here at PF and arrived at a somewhat intuitive explanation of the effect. But I don't remember what thread. I can't find anything in PF about it. And anyway I would prefer to have some outside source----preferably edited, like an online science encyclopedia----or a Wiki article if they had something besides this stub. But anything would help. Anybody have a link for this?
