Abstract

As well-known that in order to explain the zero result of the Michelson-Morley experiments (M-M experiments), Lorentz proposed the Lorentz formula of coordinate transformation and led to the birth of Einstein's special relativity. The authors carefully re-examine the M-M experiment and find a serious problem. The premise of the M-M experimental calculations was that the light source was fixed on the absolutely stationary reference frame of the universe (or the ether stationary reference frame). However, in the actual experiments, the light source was fixed on the earth motion reference frame, moving and rotating with the interferometers, which lead to the invalid calculation result of the M-M experiment. In this paper, the correct calculation method is used to prove that the zero result of the M-M experiment can be well explained by using the Galilean relativity principle and the Galilean velocity addition rule. Therefore, the most important experimental foundation of special relativity does not exist. The Lorentz coordinate transformation formulas become unnecessary, and the principles of special relativity and the invariant speed of light are unnecessary too. The experimental tests of special relativity are also discussed briefly. It points out that these experiments are either wrong or have other explanations, and the explanations of special relativity are not unique ones. Physics should give up the Lorentz transformation formula and the Einstein's special relativity completely, introduce the cosmic absolute stationary reference frame, and establish the kinetic theory based on the mass-velocity formula which should be considered as an empirical formula, to solve the fundamental problems in astrophysics and cosmology thoroughly.
