John Stachel: "But this seems to be nonsense. How can it happen that the speed of light relative to an observer cannot be increased or decreased if that observer moves towards or away from a light beam? Einstein states that he wrestled with this problem over a lengthy period of time, to the point of despair. We have no details of this struggle, unfortunately. Finally, after a day spent wrestling once more with the problem in the company of his friend and patent office colleague Michele Besso, the only person thanked in the 1905 SRT paper, there came a moment of crucial insight. In all of his struggles with the emission theory as well as with Lorentz's theory, he had been assuming that the ordinary Newtonian law of addition of velocities was unproblematic." http://www.aip.org/history/exhibits/...relativity.htm

So Einstein vandalized sensible concepts - space, time, the law of addition of velocities - in order to introduce something that seemed nonsense to him! The world accepted the insanity and... physics died.

the speed of light is constant = Einstein's greatest blunder
