Inertial systems, Galileo's relativity principle, observer's motion, Einstein's principle of relativity, arguments against STR
Einstein, trying to extend the principle of Galileo's relativity to
optical phenomena, did not understand the essence of the principle of relativity, which consists in the fact that only those phenomena observed inside the inertial system do not allow to determine whether this system moves with respect to any other system. In all the justifications for its special theory of relativity, it is not the experiments conducted inside the inertial system that are being considered, but the experiments in which external signals are analyzed, that is, signals that go from one system to another. The use of signals external to inertial systems and the absence of experiments and observations confirming the independence of the speed of light from the motion of the observer allows us to make an unambiguous conclusion about the error in the postulate of the invariance of the speed of light and the special relativity theory based on this postulate.
