By combining his 1905 postulates Einstein deduced the obvious nonsense that the speed of light relative to the observer is independent of the speed of the observer (any reasonable interpretation of the Doppler effect shows that the speed of light is different for differently moving observers). Einstein "explained" the nonsense in terms of spacetime - an even greater nonsense that killed physics in the end:

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."
https://www.aip.org/history/exhibits/einstein/essay-einsteins-time.htm
Peter Galison: "Only by criticizing the foundational notions of time and space could one bring the pieces of the theory - that the laws of physics were the same in all constantly moving frames; that light traveled at the same speed regardless of its source - into harmony."
That the speed of light relative to the observer CANNOT be independent of the speed of the observer is obvious. When the initially stationary observer starts moving towards the light source, with speed v, he sees the same wavelength (λ'=λ) but a different frequency (f'=(c+v)/λ) and a different speed of light (c'=c+v), in violation of Einstein's relativity:

"Thus, the moving observer sees a wave possessing the same wavelength [...] but a different frequency [...] to that seen by the stationary observer."

Roger Barlow: "Moving Observer. Now suppose the source is fixed but the observer is moving towards the source, with speed v. In time t, ct/λ waves pass a fixed point. A moving point adds another vt/λ. So f'=(c+v)/λ."

"Let's say you, the observer, now move toward the source with velocity vO. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: v'=v+vO. The frequency of the waves you detect is higher, and is given by: f'=v'/λ=(v+vO)/λ."

Albert Einstein Institute: "The frequency of a wave-like signal - such as sound or light - depends on the movement of the sender and of the receiver. This is known as the Doppler effect. [...] Here is an animation of the receiver moving towards the source:
Loading Image... (stationary receiver)
Loading Image... (moving receiver)
By observing the two indicator lights, you can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, the distances between subsequent pulses are not affected, but still there is a frequency shift: As the receiver moves towards each pulse, the time until pulse and receiver meet up is shortened. In this particular animation, which has the receiver moving towards the source at one third the speed of the pulses themselves, four pulses are received in the time it takes the source to emit three pulses." [end of quotation]
Since "four pulses are received in the time it takes the source to emit three pulses", the speed of the pulses relative to the receiver (observer) is greater than their speed relative to the source, in violation of Einstein's relativity.
Barlow's lecture quoted above introduces relativistic corrections (time dilation) and the frequency measured by the moving observer becomes
f' = γ(c+v)/λ
The speed of the light relative to the moving observer is, accordingly,
c' = λf' = γ(c+v)
Clearly, Einstein's relativity is violated even if the relativistic corrections are taken into account.
In order to prevent Divine Albert's Divine Theory from collapsing, Einsteinians avoid the dangerous formula f'=γ(c+v)/λ and teach the equivalent relation
f'/f = sqrt((1+v/c)/(1-v/c))
where the variation of the speed of light is safely hidden.
