Abstract

In all the literature supporting Einstein's special relativity theory (SRT) there does not exist a single comprehensive analysis investigating whether the reciprocity or symmetry features are physically possible. The features in question are the predictions that observers in relative motion will each find the other's clocks running slow, will find the other's meter sticks shortened and will encounter similar contradictions on the subject of simultaneity and synchronization of clocks.  In the absence of a proper analysis the majority of physicists believe that SRT contains no contradictions. Experimental evidence refutes the reciprocity of special relativity time dilation. An analysis of the simple process of measuring time intervals reveals that the SRT reciprocity features are indeed contradictory, which proves Einstein's observer-referenced constant speed of light cannot exist. The Lorentz transformation equations based upon this principle are thereby reduced to purely mathematical concepts with no bearing upon physical theory.
