If the speed of light is constant as per Einstein, the wavelength varies as shown here: https://youtu.be/3mJTRXCMU6o?t=77. The variation is blatantly absurd: wave crests in front of a very fast moving emitter will remain in the vicinity of the emitter for a very long time. Theoretical physicists couldn't care less.

Variable Wavelength of Light https://www.youtube.com/watch?v=xsVxC_NR64M : realistic or nonsense? VWL clearly violates the principle of relativity. The emitter could measure the variations inside his spaceship - so he would know his spaceship's speed without looking outside. Conclusion: VWL is nonsense.

When light waves move from one medium to another, say from a faster to a slower medium (vacuum- air) they must become compressed or they would not retain the information of the relative velocity in a Doppler shift. The relative motion of Sirius and the Sun would be lost. In reality, we know it is 5.5 km/sec because of compression waves. This is because, before the light of Sirius moves through interstellar gas it has a speed of C + 5.5 km/sec. When it enters that gas compression waves form encoding that information. Otherwise, light speed would have to be mostly unaffected by its medium and we know that is not the case. It is in fact tightly constrained by the medium..

What is left of relativity? There is a pointless Lorentz Transformation that serves no purpose. It is not needed to determine the speed of light because that is determined by the medium. We are still left with additive velocity, sometimes denied by relativists and sometimes accepted as "closing speeds." Relativity is entirely unnecessary.
