This doesn't bother Seto. He embraces contradictory sentences. He likes saying things like "Every observer in his own inertial frame assumes he is in THE absolute rest frame", even though two different observers are in different inertial frames and cannot possibly claim to be in the one, unique absolute rest frame. When such obviously nonsensical contradictions arise, Seto blames SR rather than himself for coming up with it.

That's your problem -- the PoR makes no mention of "absolute frame" at all, yet you persist in reading something that isn't there [#]. As I keep saying and you keep ignoring: YOU NEED TO LEARN HOW TO READ. [#] Try searching Einstein's translated paper for "absolute frame": http://www.fourmilab.ch/etexts/einstein/specrel/www/ Tom Roberts

That's what I said. > Relativity makes the explicit assertion -- in black and white -- that > there is no absolute rest frame at all. No such assertion.....I can be convinced if you point out where Einstein made such assertion. Also if there is no absolute rest frame then why does an SR observer uses the exclusive properties of the absolute rest frame to derive its math? Also can you tell me what are the differences between an inertial frame and an absolute rest frame? Here's what I think the properties of an absolute rest frame: 1. All the clocks in the universe moving wrt the absolute rest observer are running slower than the absolute rest clock. 2. All the ruler in the universe moving wrt the absolute rest observer are contracted compared to the absolute rest ruler. 3. The speed of light is isotropic and a constant math ratio in the absolute rest frame. >Period. The rest of what > you've said below is wrong, because it follows from this mistake.

The PoR is the main postulate. It allows an SR observer to use any frame to derive its math and the simplest frame is the absolute rest frame. Ken Seto > > > > > > > Ken Setp > > > > > > 4.
