Alberto Martinez: "Does the speed of light depend on the speed of its source? Before formulating his theory of special relativity, Albert Einstein spent a few years trying to formulate a theory in which the speed of light depends on its source, just like all material projectiles. Likewise, Walter Ritz outlined such a theory, where none of the peculiar effects of Einstein's relativity would hold. By 1913 most physicists abandoned such efforts, accepting the postulate of the constancy of the speed of light. Yet five decades later all the evidence that had been said to prove that the speed of light is independent of its source had been found to be defective."
Two examples of defective (more precisely, fraudulent) but glorious confirmation of Einstein's 1905 false constant-speed-of-light postulate:

"The de Sitter effect was described by de Sitter in 1913 and used to support the special theory of relativity against a competing 1908 emission theory by Walter Ritz that postulated a variable speed of light. De Sitter showed that Ritz's theory predicted that the orbits of binary stars would appear more eccentric than consistent with experiment and with the laws of mechanics, however, the experimental result was negative. This was confirmed by Brecher in 1977 by observing the x-rays spectrum."
Here is Brecher's paper:

K. Brecher, "Is the Speed of Light Independent of the Velocity of the Source?"
Brecher (originally de Sitter) applies the emission theory to a system with unknown parameters and informs the gullible world that, if the emission theory was correct, the system would produce "peculiar effects". For instance, Brecher has no idea how the gravitational field of the system affects the speed of the emitted light, and accordingly calculates the "peculiar effects" by omitting this parameter.
Needless to say, the system does not produce the strawman "peculiar effects". Conclusion: Ritz's emission theory (more precisely, the assumption that the speed of light depends on the speed of the emitter) is unequivocally refuted, Divine Einstein, yes we all believe in relativity, relativity, relativity.
A refutation of this kind can only be "valid" in Einstein's schizophrenic world. Note that it cannot be criticized - the fact that the parameters of the double star system are unknown prevents critics from showing why exactly the "peculiar effects" are absent.
De Sitter's arguments "have been criticized" but the Alväger experiment "is unambiguous", Divine Einstein, yes we all believe in relativity, relativity, relativity:

Michael Fowler, University of Virginia: "There is another obvious possibility, which is called the emitter theory: the light travels at 186,300 miles per second relative to the source of the light. The analogy here is between light emitted by a source and bullets emitted by a machine gun. The bullets come out at a definite speed (called the muzzle velocity) relative to the barrel of the gun. If the gun is mounted on the front of a tank, which is moving forward, and the gun is pointing forward, then relative to the ground the bullets are moving faster than they would if shot from a tank at rest. The simplest way to test the emitter theory of light, then, is to measure the speed of light emitted in the forward direction by a flashlight moving in the forward direction, and see if it exceeds the known speed of light by an amount equal to the speed of the flashlight. Actually, this kind of direct test of the emitter theory only became experimentally feasible in the nineteen-sixties. It is now possible to produce particles, called neutral pions, which decay each one in a little explosion, emitting a flash of light. It is also possible to have these pions moving forward at 185,000 miles per second when they self destruct, and to catch the light emitted in the forward direction, and clock its speed. It is found that, despite the expected boost from being emitted by a very fast source, the light from the little explosions is going forward at the usual speed of 186,300 miles per second. In the last century, the emitter theory was rejected because it was thought the appearance of certain astronomical phenomena, such as double stars, where two stars rotate around each other, would be affected. Those arguments have since been criticized, but the pion test is unambiguous. The definitive experiment was carried out by Alvager et al., Physics Letters 12, 260 (1964)."
Here is Alväger's paper:

Test of the second postulate of special relativity in the GeV region, Alväger, T.; Farley, F. J. M.; Kjellman, J.; Wallin, L., 1964, Physics Letters, vol. 12, Issue 3, pp.260-262
High energy particles bump into a beryllium target and as a result gamma photons leave the target and travel at c relative to the target. Antirelativists do not see how this can refute the emission theory but Einsteinians do. They teach that initially a pion is generated inside the beryllium target, and this pion travels at 0.9999c inside the target, and decays into two gamma photons inside the target, and therefore this pion is a moving source of light. And since the source travels at c inside the target, the gamma photons must travel at 2c if the emission theory is correct but they don't - they travel at c as gloriously predicted by Divine Albert's Divine Theory!
Just imagine: An object travels at some speed, then disintegrates into two fragments, and the emission theory, according to Einsteinians, predicts that the fragments should travel at twice the initial speed! What an idiotic straw man!
If the emission theory had predicted that the products of the disintegration of the pion should travel at 2c, it would be the silliest theory in the history of science. The straw man built by Alväger & Co is more than idiotic, and yet the experiment is often cited as the most convincing confirmation of Einstein's 1905 constant-speed-of-light postulate.
