Yes wormy all frames are equovalent...including the absolute frame. That's why every Sr observer uses the properties of an absolute frame to derive its math.

Inertial frame of reference http://en.wikipedia.org/wiki/Inertial_frame_of_reference "In physics, an inertial frame of reference (also inertial reference frame or inertial frame ) is a frame of reference which describes time homogeneously and space homogeneously, isotropically, and in a time independent manner. This allows motion and interactions to be described without the presence of fictitious forces. Special relativity states that there are actually infinitely many such frames, and the physical laws takes the same form as they do in any other inertial frame of the same handedness. In flat spacetimes, all inertial frames are in a state of constant, uniform motion with respect to one another". "By contrast, in non-inertial reference frames, the laws of physics are dependent upon the particular frame of reference, and the usual physical forces must be supplemented by what are called fictitious forces. All non-inertial frames are accelerating with respect to all inertial frames". Do read the reference, Ken.

ROTFLOL....you can't have something that doesn't exist as special. It appears that you can't define the differences between an inertial frame and an absolute frame....so you now say that the absolute frame is special becaus eit doesn't exit. > > >I talk about the exclusive properties of an absolute frame and every > >SR observer adopt these properties so that means that every SR > >observer assumes himself to be in a state of absolute rest. > > Which contradicts special relativity.

Right...thye PoR allows that every inertial observer assumes the same laws of physics as the preferred frame. > > > as it turns out this is also wrong. Why?

You're wrong. Right that's because every inertial observer assumes that he is in a preferred frame.
