View source for The Constancy of the Speed of Light

Einstein’s Special Theory of Relativity, published in Bern, Switzerland, in 1905, is based on two postulates, the second which is that  light is always propagated in empty space with a definite velocity, c, which is independent of the state of motion of the emitting body. There is no problem with the speed of light being independent of the state of motion of the emitting body since this is the case with waves in general, in relation to their media of propagation. The problem arises with Einstein’s claim that we don’t actually need to have a physical medium of propagation at all. This rash claim is generally interpreted as meaning that the speed of light is a universal constant which defies Galileo’s Principle of Relativity. How this could be possible physically has never to this day been satisfactorily answered, despite the fact that Einstein’s theories are claimed to have been proven experimentally on multiple occasions. A rational solution to this mystery will now be proposed. See here,
