With regard to "this is counterintuitive, if you expect John to see the evolution of the Galaxy as time dilated", I think that is the crux of the confusion in the question. When reviewing the twin paradox on wikipedia, the part that I think helps to understand is, on the return visit, the twins see events from each other passing more quickly, but if they account for the decreasing time delays, they calculate that time is passing more slowly for their twin. | |
