You are lying. I do not claim it "now". This is what I have always said for at least 40 years. Now, yes, obviously I assume it. The value (tA'-tA) = 2AB/c is the same not only for A and B, but also for all the stationary points of the inertial frame of reference of A and B. Better, if I change frame of reference it will remain true, by invariance of the transverse speed of light in any frame of reference. On the other hand the value tB-tA (go) will vary for most observers in R (where A and B are stationary), as will the value tA'-tB (return). But you cannot understand this, because 1. You are stupid and because 2. because you are tied up with relativistic thoughts all learned, but false. R.H.
