   If I am an accelerating observer, and if I OBSERVE a TV image of the   
   distant person, that tells me what that distant person looked like a   
   long time ago.  That's not meaningful to me, because I don't know how to   
   determine how much she aged while the message was in transit.   
      
   But if I'm mutually stationary wrt the array of clocks that I have   
   previously described, which provides a "NOW" for me extending throughout   
   space, that DOES give me a meaningful answer to the question of how old   
   she currently is.  And by "meaningful", I mean that I REALLY believe   
   that she is currently that age.  The only way I can be wrong about her   
   current age is if my equation for the rate ratio of the two clocks is   
   wrong.  I'm confident that it is correct.  I think it IS experimentally   
   testable.   
      
   I don't understand what you meant in the above, when you said   
   "regardless of whether anything else in the universe   
   is affected".  Although I realize that the way I accelerate affects what   
   I conclude about how her age changes, I don't contend that that has ANY   
   effect on what other observers (including she herself) conclude about   
   her age changes.  Different people disagree about simultaneity at a   
   distance. That's just the way special relativity is.
