"Einstein's theory of relativity clashes with common sense (...) Albert Einstein's starting point for his theory was his insistence that the laws of physics must be the same for observers at rest or travelling at constant speed. Applying this seemingly reasonable principle to the phenomenon of electromagnetism, he arrived at a much less reasonable postulate: namely, that the speed of light in a vacuum (the speed at which an electromagnetic wave travels) must be the same for all, irrespective of the motion of source or observer. (...) My own view is that relativity scepticism presents an interesting case of a "clean" mistrust of science. After all, the predictions of relativity are not in conflict with religious dogma, political worldviews or vested interests (unlike evolution, climate science or tobacco science). I suspect that the scepticism stems from the fact that relativity makes predictions that are apparently in conflict with our everyday "common sense" experience of the world."
Relativity scepticism stems from the fact that relativity makes predictions that are in conflict WITH REASON, not with our common sense experience of the world. The "much less reasonable postulate" is actually idiotic. Consider a light source emitting a series of short pulses the distance between which is d (e.g. d = 300000 km). A stationary observer/receiver measures the frequency of the pulses to be f=c/d:

The observer starts moving with (small) speed v towards the source - the measured frequency shifts from f=c/d to f'=(c+v)/d:

Why does the frequency shift from f=c/d to f'=(c+v)/d ?
Reasonable answer (given by both Newton's emission theory of light and Maxwell's 19th century electromagnetic theory; valid for all kinds of waves and fatal for Einstein's relativity): Because the speed of the pulses relative to the observer shifts from c to c'=c+v.
Idiotic ad hoc answer (devised to save Einstein's relativity; so obviously idiotic that Einsteinians never state it explicitly): Because something happens to the observer so that what was previously d to him now appears to be d'=cd/(c+v).
