You are in error: Assumption G1. "However, as per the Newtonian notion of absolute time and length, we may define an absolute or universal reference frame..." Assumption G2. "Let us further assume that the two spacecrafts A and B are fitted with appropriate .. mutually synchronized identical atomic clocks." Assumption G3. You then proceed in your section 1 to assume that those clocks are also simultaneously synchronized to the "absolute" reference frame. *You* made those extra assumptions. SR specifically does *not* make those assumptions. In fact, it is a formal logical consequence of the two postulates of SR that clocks in different inertial frames are not synchronizable. It is no wonder that if you arrive at contradictory results. The contradiction arises because *you* made mutually contradictory assumptions. You seem to think that the assumption of Newtonian relativity is somehow not an assumption, which is bizarre and incorrect. CM

(a) "exponential" has a specific meaning in mathematics which is certainly not what you describe (instead it is e^x where e is a constant); (b) a fairly simple analysis shows that the SR equation for energy grows as 1/2 mv^2 for small v, just as expected from classical mechanics; "NoEinstein" is incorrect.

For the natural days are truly unequal, though they are commonly considered as equal and used for a measure of time; astronomers correct this inequality for their more accurate deducing of the celestial motions. It may be, that there is no such thing as an equable motion, whereby time may be accurately measured " Isaac Newton "Here take notice, that the Sun or the Earth passeth the 12. Signes, or makes an entire revolution in the Ecliptick in 365 days, 5 hours 49 min. or there about, and that those days, reckon'd from noon to noon, are of different lenghts; as is known to all that are vers'd in Astronomy." Huygens The continuous progression of equable 24 hour days derived artificially from natural noon also substituted for constant daily rotation at a rate of 15 degrees per hour and it still does,hence there is no external reference for rotation through 360 degrees as Flamsteed had it in his attempt to tie daily rotation directly to stellar circumpolar motion in 'sidereal time'. All these absolute/relative definitions of space,motion,at least as they are used today,have very little in common with Isaac's intentioned uses and it appears readers are absolutely content to ignore the difference between fact and fiction in order to make relativity and the later 'no center/no circumference' ideologies more interesting on account of a few screwed up references and a few bad assumptions.From my seat it is an amazing spectacle on two fronts,the actual train wreck of timekeeping references as they are derived from astronomical sources being the major one but also the willingness of readers to subdue their own reasoning abilities in accepting the story that evolved and emerged as a result of not comprehending exactly what Isaac was up to.And so it remains to this day.
