I would never have guessed! Why not consider the CMBR as the local clock for each galaxy? What then? Does AE precisely define a "clock"? AG *

It has nothing to do with the problem I posed. Obviously, you have no clue. Oh, one other thing; why is it that everything that CAN happen, MUST happen? Why do you refuse to answer this question? Oh, I know; you have no clue. End of story.
