Give us a reference from any of Einstein's writings on SR that accepts the existence of any sort of absolute frame. You can't, because in contrast he states that all inertial frames are equivalent, and there's simply no need for an inertial frame. >> >There is only one absolute frame. >> >> No, there aren't any, according to SR. >Wrong in SR an inertial frame is considered to be an absolute frame. Wrong.

SR says >that all frames are equivalent, including the absolute frame. You are the idiot, redefining SR to include some sort of absolute frame. I already gave you a reference to Einstein's SR paper (which I notice you didn't respond to) where the *only* references to an absolute frame was stating it was not necessary and would not be used.

Describe for us *any* two inertial frames where either a clock in one ticks faster or a ruler is lengthened as seen from the other. |
