well -somebody first need to prove that there is something to measure ;

what's that thing - "light" , anyway ?

Special Relativity cannot be proven. SRT only applies to cases with no acceleration or gravity. Since there is gravity everywhere in our universe, no SRT experiment can be performed in the absence of gravity.

The minor flaw in your argument is that general relativity includes special relativity as a limiting case. Every time GR has been tested it passes the test, while other rival theories seem to fall one by one. If GR is true, then SR has to be true too. BTW if you want proof then you have to do mathematics, not physics. Science never proves anything, and never claims to. It is only journalists and the public who demand proof, which shows they don't actually understand what they are asking.

One day GR will fail a test, and a new theory will be needed. This new theory will almost certainly include GR as a limiting case, so in turn will include SR too.

To be honest, I wish GR were not true because I don't like the idea of physics being hijacked by geometers but I can't argue with experimental data. You might wish SR were not true. The experiments say you are wrong.

7n7is, there is merit in your thinking. In science, the general approach is to observe, produce a hypothesis for the observation and then test the hypothesis via experiment.

The scientific approach never produces PROOF.

It only produces evidence which supports or destroys a hypothesis. That is one of the reasons scientists speak of "theory". Theory does not mean "not fact", it means "most acceptable model".

To weaken a given hypothesis will require just ONE repeatable experimental observation which departs from the proposed model, even if there are numerous other experiments which confirm the hypothesis.

The outlier result will point to the fact that the hypothesis is incomplete and needs revising, assuming the experiments have been correctly done.

On the speed of light (c): There is no PROOF, only evidence, that it is constant in a given medium at this time.

Hope this helps.

"light is an electromagnetic disturbance, propagated through the field according to electromagnetic laws"

Turns out to be a disturbance, that so-called "light". Better close the blinds then...

Light is the opposite of Heavy. Or in Advertising speak, Lite is the opposite of "Full Flavored". Of course all this is relative.

To heck with all this "lite". How about 80-proof? Warp drive was invented by a drunk.

General Relativity has nothing to do with Special Relativity and has nothing to do with relativity in general. It was called this by Einstein and his followers to help cover up Einstein's plagiarism and use mystification to try to cover up the logical absurdities. Einstein wasn't the first to propose that a beam of light bent in a gravitational field. Soldner did that long before Einstein, so did Isaac Newton. Einstein plagiarized Gerber's and Hilbert's mathematics when working on GR, too.

Special Relativity has nothing to do with relativity, either. Its based on the wrong assumption that aether drift experiments measure an absolute velocity based on the wrong assumption that the aether is at absolute rest. Lorentz published in 1895 that the aether is NOT at absolute rest based on his theory. Also, undergraduate physics experiments prove gravity is NOT curved space since the path of a falling object or projectile in a gravitaional field is affected by its velocity. If it was curved space, all projectiles would follow the same path in spite of its velocity which doesn't happen. Eric Baird explains gravity with his aether density gradient theory, ie. the properties of the aether vary with gravitational potential. This explains the difference in speed of light with gravitational potential and the gravitational time dilation effect.

Stellar aberration experiments with binary stars also proves that the earth is moving through the transmitting medium of light, ie. the aether exists and the pre-Einsteinian aether theories are right and Einstein is wrong.

There is no point in continuing this discussion. Learn some physics, even if you disagree with it. Find out what a geodesic is, and see how in flat space it naturally includes SR. Find out how gravitational bending of light predicted by GR (confirmed by experiment) is different from the naive classical value.

I have nothing more to say.
