Relativity is retarded. Einstein was a genius for retards..

  Why did Einstein postulate that the speed of light is independent to the motion of the source, if that is EXACTLY what classical wave physics says ?? The speed of sound is also independent to the motion of the source. Did Einstein not know this ??

Apparently not, since he felt that classical physics could not explain this well known wave behaviour and felt the need to make a completelly new theory to explain it ! And it looks like most physicists dont know this either since they consider Einstein's postulate so revolutionary and groundbreaking. Seriously, these people are just plain ignorant and stupid. No wonder they consider Einstein a genius (to be fair even some of the ones who try to disprove Einstein are also dumb, because they try to disprove him by questioning the validity of his 2nd postulate, which is probably the only thing he got right in his whole 'theory').

These relative fools actually believe that the aether does not exist because Michelson experiment could not detect a change in the speed of light caused by the motion of the earth (i.e. source) in the aether. That's like believing that the air does not exist because you can't detect a change in the speed of sound by moving the source in air. It's completelly retarded. And this is 'mainstream science' now.
Here is one example from Lumenlearning:

Lumenlearning wrote:Starting in the mid-1880s, the American physicist A. A. Michelson, later aided by E. W. Morley, made a series of direct measurements of the speed of light. The results of their measurements were startling.

Michelson-Morley Experiment

The Michelson-Morley experiment demonstrated that the speed of light in a vacuum is independent of the motion of the Earth about the Sun.

The eventual conclusion derived from this result is that light, unlike mechanical waves such as sound, does not need a medium to carry it.

First of all, the experiment was NOT done in a VACUUM. It was done in the ATMOSPHERE, which was the medium of light (comoving with the earth). They can't even get that simple fact right, and claim that Michelson demonstrated that the speed of light in a vacuum is independent to the motion of the earth. Except Air is not a Vacuum. So expecting them to get basic wave physics right is useless.

Second, there is nothing startling in the result, unless you are completelly ignorant about classical wave physics. Because the speed of sound does not depend on the motion of the source either. It only depends on the properties of the medium. Why on earth would you expect the speed of light to depend on the motion of the source ? In the classical framework where light is a wave in aether according to Maxwell theory of electromagnetism, it makes no sense to expect such thing.

It is completelly illogical and retarded to conclude that the aether does not exist because the speed of light does not depend on the speed of the source. Because that is exactly what should happen if light is a wave in aether ! So if Michelson proved that the speed of light in an 'air vacuum' does not depend on the motion of the source, that does not disprove the aether and does not contradict the classical wave theory of light in any way. It only confirms it !
