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. (...) In the above paragraphs, we have only considered moving sources. In fact, a closer look at cases where it is the receiver that is in motion will show that this kind of motion leads to a very similar kind of Doppler effect. Here is an animation of the receiver moving towards the source: (...) 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. (....) Similarly, when the receiver is moving away from the source, each pulse has to travel a slightly longer distance than its predecessor in order to reach the receiver. The result can be seen in this animation: (...) Once more, the receiver is moving at one third the speed of the pulses, this time away from the source. During the time it takes for the source to emit three pulses, only two pulses reach the receiver - the pulse frequency at the receiver is "redshifted" to 66,67 percent of the original pulse frequency at the source."
That is, the speed of light as measured by the receiver (observer) is (4/3)c when the receiver is moving towards the source and (2/3)c when the receiver is moving away from the source. Einsteinians clearly see this but, like Fermilab physicist Dr. Ricardo Eusebi, confidently decla "The speed of light as measured by the receiver is c because this speed is the same in all the reference frames, Divine Einstein, yes we all believe in relativity, relativity, relativity":

Dr Ricardo Eusebi: "f'=f(1+v/c). Light frequency is relative to the observer. The velocity is not though. The velocity is the same in all the reference frames."
Ignatius of Loyola: "That we may be altogether of the same mind and in conformity with the Church herself, if she shall have defined anything to be black which appears to our eyes to be white, we ought in like manner to pronounce it to be black."
