> Observers at a high cosmological redshift cannot watch our clocks at all. This is true, but it doesn't change the fact that the "time dilation" described in the article is like the time dilation in special relativity, and is not like gravitational time dilation, with respect to what the article is talking about. > there's no reason to think that the redshift we ascribe to them is the redshift they ascribe to our precursors. Indeed, there is every reason not to think this. But that still doesn't change the fact that the "time dilation" due to cosmological redshift is like the time dilation in SR, not gravitational time dilation, with respect to what the article is talking about.
