Consider one of Einsteiniana's demonstrations of superluminal (moving
faster than c=300000km/s) signals:

Any Einsteinian would tell you that, although superluminal signals
travel faster than c=300000km/s, they do not violate Einstein's
relativity. Then the Einsteinian may refer you to some of the numerous
idiotic explanations of this non-violability devised in Einsteiniana.
Perhaps the most idiotic one is: Superluminal signals cannot violate
relativity because they carry no information. You are shocked, first
by the oxymoron "signal carrying no information", then by the
breathtaking ability of Einstein's relativity to distinguish between
"signals carrying no information" and other signals, somewhat more
dangerous, that do carry some information.

Now ignore superluminal signals and just take a look at the wave as it
travels towards the observer (receiver). Then imagine that the
observer suddenly starts moving against the wave. The frequency he
measures will obviously increase and....what else will change? Perhaps
the speed of the wave (relative to the observer) will increase?
Perhaps the wavelength will decrease? What does the picture predict?

Einsteinians clearly see that the wavelength is independent of the
speed of the observer (that is, will remain constant) but would tell
you that it will decrease. So they would save relativity.

Honest scientists also see that the wavelength is independent of the
speed of the observer (that is, will remain constant) and would tell
you that the speed of the wave (relative to the observer) will
unavoidably increase. So they would kill relativity.

The crucial question is: Why are honest scientists silent in
Einstein's world?
