Abstract

This paper is an update to our earlier paper1 entitled ?Theory of Special Relativity vs. Preferred Reference Frame Theory: A theoretical distinction?. This updated version simplifies the arguments used in the former paper by removing unnecessary calculations and using only logical arguments. It does not involve calculations or use of the Lorentz equations. This will remove many ambiguities and objections some might have concerning our earlier paper. We will once more conclude that Einstein's Theory of Special Relativity is not equivalent to modern ether theories. We suggest that the reader review section 1 and section 2 of the former paper in which we introduce Preferred reference Frame Theories (PFT).
