BTW such assumption is the reason why SR is incomplete. SR is valid only if the observed frame is in a higher state of absolute motion such as in the accelerator design applications. >even though two different > observers are in different inertial frames and cannot possibly claim > to be in the one, unique absolute rest frame. But that's exactly what every SR observer assumes. In real life such SR assumption is valid if the observed frame is in a higher state of absolute motion than the observer.

Oh, good grief, Seto. You don't even have his writings available to you.

If you are bonehead-ignorant of what SR says, that is not my problem. I can point you to things you can read where you can see for yourself what SR says, so you won't continue to make bonehead claims that SR says "A", when SR in fact says "not A". > > >I don't > > know why you are looking for that statement to be included in the PoR. > > Special relativity involves more than the one-sentence PoR. > > The PoR is the main postulate. SR is more than a postulate.
