Sounds counterintuitive, but the way I wrapped my head around it seemed to make sense as when one thinks about it there exists an obviously fixed area of sky; an observer from a static earth would therefore see light radiated from an object 500 million light years away with a diameter larger than light radiated at the same time as the "first" light reaches the observer, which assuming a rate of expansion faster than light could be far greater than double the original separation distance.

Taken to far distant lengths, galaxy which radiated its light our way many billions of years ago would appear anomolously large for its true distance by virtue of its light having left on its travels so long ago that the object's current distance (calculated by redshift ect) would far exceed its possible value not accounting for cosmological expansion.

Anyway this is all a bit disjointed I know but does any of this make sense to those with education? Can anyone divine out the "real" question I have with what I can come up with here? Thanks all.
