Einstein's 1905 assumption that the speed of light is independent of the motion of the source was false but sounded reasonable - an analogous statement is true for waves other than light. However, combined with the principle of relativity, the assumption entails nonsense - the speed of light must be independent of the motion of the observer as well:
John Stachel: "But here he ran into the most blatant-seeming contradiction, which I mentioned earlier when first discussing the two principles. As noted then, the Maxwell-Lorentz equations imply that there exists (at least) one inertial frame in which the speed of light is a constant regardless of the motion of the light source. Einstein's version of the relativity principle (minus the ether) requires that, if this is true for one inertial frame, it must be true for all inertial frames. 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://history.aip.org/history/exhibits/einstein/essay-einstein-relativity.htm
The fact that the speed of light VARIES with the speed of the observer is as obvious as 2+2=4 (Einstein's nonsensical conclusion that it doesn't is equivalent to Big Brother's 2+2=5):
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:
Stationary receiver: Loading Image...
Moving receiver: Loading Image...
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]
"Four pulses are received in the time it takes the source to emit three pulses" means that the speed of the pulses relative to the moving receiver (observer) is greater than their speed relative to the source, in violation of Einstein's relativity.
Einsteinians never think of the speed of the pulses relative to the moving observer:
"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." http://ebooks.adelaide.edu.au/o/orwell/george/o79n/chapter2.9.html
