Default CONSTANT OR VARIABLE SPEED OF LIGHT?

The observer starts moving towards the wave source, and the wavecrests start hitting him more frequently, that is, the frequency he measures increases.. Now the crucial question:

Why do the wavecrests hit the observer more frequently?

For all waves other than light waves, the indisputable answer is:

Because the speed of the wavecrests relative to the observer has increased.

For light waves, Newton, Maxwell and most antirelativists would give the same answer:

Because the speed of the wavecrests relative to the observer has increased (in violation of Einstein's relativity).

Einsteinians would not answer the crucial question:

"Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."

Default CONSTANT OR VARIABLE SPEED OF LIGHT?

In order for the speed of the waves (relative to the observer) to remain constant, the motion of the observer should affect the wavelength in the following idiotic way:

http://astro.berkeley.edu/~mwhite/da...plershift.html
Professor Martin White, UC Berkeley: "...the sound waves have a fixed wavelength (distance between two crests or two troughs) only if you're not moving relative to the source of the sound. If you are moving away from the source (or equivalently it is receding from you) then each crest will take a little longer to reach you, and so you'll perceive a longer wavelength. Similarly if you're approaching the source, then you'll be meeting each crest a little earlier, and so you'll perceive a shorter wavelength. (...) The same principle applies for light as well as for sound. In detail the amount of shift depends a little differently on the speed, since we have to do the calculation in the context of special relativity. But in general it's just the same: if you're approaching a light source you see shorter wavelengths (a blue-shift), while if you're moving away you see longer wavelengths (a red-shift)."
