The Albert Einstein Institute unwittingly disproves Einstein's relativity (http://www.einstein-online.info/spot...doppler.html):

Albert Einstein Institute: "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." [end of quotation]

Since "the distances between subsequent pulses are not affected", the frequency shift is caused by a speed-of-light shift, in accordance with the formula

(frequency) = (speed of light)/(distance between pulses)
