Special relativity is an artefact of human stupidity. Time dilation is a brain flatulation

Time dilation can be inferred from the observed constancy of the speed of light in all reference frames dictated by the second postulate of special relativity. This constancy of the speed of light means that, counter to intuition, the speeds of material objects and light are not additive. It is not possible to make the speed of light appear greater by moving towards or away from the light source.

The speeds of material objects and sounds waves are not additive either. It is not possible to make the speed of sound appear greater by moving towards and away the sound source. The frequency yes, but not the speed. So what are these relative scientists arguing here ? That because the speed of light does not increase with the speed of the source, Einstein's theory is right ? They are clearly confused and do not understand how waves propagate in a medium.

The reason why you cant combine the speeds is because the speed of the sound wave, or any other wave, only depends on the properties of the medium. It does not depend on the properties of the source. A moving source will only change the perceived frequency and wavelength of a sound wave due to the Doppler effect. The speed of sound waves in different frames remains constant because it is entirely and absolutely dependent of their medium of propagation and has absolutely nothing to do with the moving of the source in the medium. That is why the speed of sound waves remains constant in different frames, no matter how fast the source or observer is moving.

Why would one expect the speed of light waves to be different in different frames ?

In a static medium with no wind, the speed of sound remains constant. The Doppler effect changes the frequency and wavelength based on the relative motion of the source and observer, but not the speed of sound itself. The speed depends on the properties of the medium, like temperature and pressure, not on the motion of the source or observer.

The speed of transmission of the sound remains a constant regardless of the frequency or the wavelength. The speed of sound only depends on the state of the air (or gas) not on the characteristics of the generating source.

Even the relative scientists from NASA understand that the speed of sound waves remains a constant regardless of the movement of the source or observer (which changes frequency/wavelength due to Doppler effect), because it only depends on the medium. But they can't apply the same basic principle of wave propagation to light waves and aether, because they are fools. Just like Einstein and all relative scientists are.

Who interpreted the Michelson-Morley experiment in the most foolish way possible, based on their foolish assumption or 'intuition' that the speed of the light wave should change depending on the movement of the earth source through the aether. And foolishly concluded that if there was no such change detected experimentally, then the medium of light waves did not exist. And on this basis rejected the aether. On the same basis, they can conclude that air does not exist either !

This just shows once more that Einstein was right...when he said that human stupidity is infinite.
