You seem to be in strong denial, but let me try one last time:
Getting to know dimensions of a physical body (x1, x2,...) in SRT is not associated with an interval of time. While time is passing by, in any given moment, getting to know its start and end coordinates is a timeless task, those are not "events". By failing to see this you get to conclusion that only in an physically meaningless case (Dx = Dx' = Dt = Dt' = 0 or v = 0) space contraction and time dilation happen in accordance with Dx' = Dx sqrt(1-v^2/c^2) Dt' = Dt / sqrt(1-v^2/c^2) It is in accordance with SRT that these formulas as valid at any moment of time, all the time. Physically taken "together" these formulas -- yes, it means a traveling rod with be perceived as contracted, at any given time, as well as a clock that is travelling with the rod will tick slower, at the same time, any given time.

Another idiot than believes semantic wanking counts for physics. Rest of rubbish mercifully snipped. Bill |
