Einstein's 1905 constant-speed-of-light postulate:

Albert Einstein, ON THE ELECTRODYNAMICS OF MOVING BODIES, 1905: "...light is always propagated in empty space with a definite velocity c which is independent of the state of motion of the emitting body."

This independence from the state of motion of the light source is only conceivable if the motion of the source is able to change the wavelength of the emitted light. So Einsteinians universally teach the following:

Stephen Hawking, "A Brief History of Time", Chapter 3: "Now imagine a source of light at a constant distance from us, such as a star, emitting waves of light at a constant wavelength. Obviously the wavelength of the waves we receive will be the same as the wavelength at which they are emitted (the gravitational field of the galaxy will not be large enough to have a significant effect). Suppose now that the source starts moving toward us. When the source emits the next wave crest it will be nearer to us, so the distance between wave crests will be smaller than when the star was stationary."

The interpretation implies that the speed of the wavecrests relative to the moving source is smaller than c (unlike the stationary source, the moving source is chasing the fleeing wavecrest) - an implication which is obviously wrong. Accordingly, the underlying assumption - that the moving source emits shorter wavelength - has to be rejected. The moving source does not emit shorter wavelength - it emits faster light. If the speed of the source is v, the speed of the light relative to the observer is c'=c+v, in violation of Einstein's relativity.
