My comment on the site (deleted immediately by Uzan):
Physics speaks of a world in which the speed of light does not depend on the speed of the observer, but this world does not exist. The speed of light VARIED with the speed of the observer, in violation of Einstein's relativity - it varied in Maxwell's theory of the nineteenth century, and the Doppler effect proves this variation today:
Gabrielle Bonnet, Normal School Superior of Lyon: "Maxwell's equations are in particular a constant, c, which is the velocity of light in a vacuum, by a change of classical referential, if c is the speed of light in The vacuum in a first referential, and if we now place ourselves in a new referential in translation with respect to the first at the constant velocity v, the light should henceforth go at the speed cv if it moves in the direction and direction of v , And at the speed c + v if it moves in the opposite direction. "
"Doppler Effect: When the observer or the source of the wave moves, the perceived frequency is modified [...] 1. mobile observer (v), fixed source ==> modification
Perceived: c '= c ± v ==> f' = c '/ λ. "
Quote: "vO is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + vO. [...] The motion of an observer does not alter the wavelength. The increase in frequency is a result of the observer encountering more wavelengths in a given time."
