Default Basic Principles of Future, Einstein-Free Physics

Albert Einstein Institute: "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."

Two crucial facts in the stationary-source-moving-receiver scenario:

(A) Speed and frequency of light pulses vary proportionally for the receiver/observer.

(B) Wavelength (distance between light pulses) remains constant.

(A) and (B), generalized over any possible scenario (e.g. moving-source-stationary-receiver, light-falling-in-gravity), will become basic principles of future, Einstein-free physics (if it's not too late for resurrection of physics).
