John Stachel: Einstein's constant speed of light "seems to be nonsense":

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." http://www.aip.org/history/exhibits/...relativity.htm

The constancy of the speed of light is OBVIOUS NONSENSE. Frequency and speed of light pulses vary proportionally for the moving observer https://youtube.com/watch?v=bg7O4rtlwEE, in accordance with the formula

(frequency) = (speed of pulses)/(distance between pulses)
