Richard Feynman's Fraudulent Logic

Richard Feynman: "Suppose we are riding in a car that is going at a speed u, and light from the rear is going past the car with speed c. [...] ...according to the Galilean transformation the apparent speed of the passing light, as we measure it in the car, should not be c but should be c-u. For instance, if the car is going 100,000 mi/sec, and the light is going 186,000 mi/sec, then apparently the light going past the car should go 86,000 mi/sec. In any case, by measuring the speed of the light going past the car (if the Galilean transformation is correct for light), one could determine the speed of the car. A number of experiments based on this general idea were performed to determine the velocity of the earth, but they all failed - they gave no velocity at all. [...] As mentioned above, attempts were made to determine the absolute velocity of the earth through the hypothetical “ether� that was supposed to pervade all space. The most famous of these experiments is one performed by Michelson and Morley in 1887." http://www.feynmanlectures.caltech.edu/I_15.html

The Michelson-Morley experiment "gave no velocity at all" because the principle of relativity was operative in that case - all parts of the experiment, including the emission and the detection of the light, occurred WITHIN the moving system.

In the car case the light comes "from the rear" - the experiment is not entirely performed within the moving system and the principle of relativity is irrelevant. Nothing prevents people in the car from measuring the speed of light as c-u.

Einstein's 1905 first postulate (the principle of relativity) is obviously true while the second postulate (the constancy of the speed of light) is obviously false. If the world can be misled into believing that the constancy of the speed of light is a logical consequence of the principle of relativity, or, equivalently, that variable speed of light contradicts the principle of relativity, all problems of the Einstein cult are solved. The consequence, the constancy of the speed of light, becomes just as true as the premise, the principle of relativity.

Einstein (and later Feynman) did manage to mislead the gullible world:

Albert Einstein: "If a ray of light be sent along the embankment, we see from the above that the tip of the ray will be transmitted with the velocity c relative to the embankment. Now let us suppose that our railway carriage is again travelling along the railway lines with the velocity v, and that its direction is the same as that of the ray of light, but its velocity of course much less. Let us inquire about the velocity of propagation of the ray of light relative to the carriage. It is obvious that we can here apply the consideration of the previous section, since the ray of light plays the part of the man walking along relatively to the carriage. The velocity W of the man relative to the embankment is here replaced by the velocity of light relative to the embankment. w is the required velocity of light with respect to the carriage, and we have w = c - v. The velocity of propagation of a ray of light relative to the carriage thus comes out smaller than c. But this result comes into conflict with the principle of relativity set forth in Section V." http://www.bartleby.com/173/7.html

Albert Einstein, On the Principle of Relativity: "After all, when a beam of light travels with a stated velocity relative to one observer, then - so it seems - a second observer who is himself traveling in the direction of the propagation of the light beam should find the light beam propagating at a lesser velocity than the first observer does. If this were really true, then the law of light propagation in vacuum would not be the same for two observers who are in relative, uniform motion to each other - in contradiction to the principle of relativity stated above." https://einsteinpapers.press.princet.../vol6-trans/16

The brainwashing argument devised by Einstein and Feynman is perhaps the most idiotic in the history of science (only Neil deGrasse Tyson's "cosmic conspiracy of the highest order" is more idiotic). Here is the argument:

The constancy of the speed of light is a logical consequence of the principle of relativity. Therefore it is just as true as the principle of relativity. Variable speed of light contradicts the principle of relativity and is therefore untenable.

Two almost identical versions of the syllogism ("Einstein" is replaced by "Maxwell" in the second version):

Premise 1: The laws of physics are the same in every inertial frame (principle of relativity).

Premise 2: Einstein said that the speed of light is a law of physics.

Conclusion: The speed of light is the same in every inertial frame:

Leonard Susskind: "The principle of relativity is that the laws of physics are the same in every reference frame. That principle existed before Einstein. Einstein added one law of physics - the law of physics is that the speed of light is the speed of light, c. If you combine the two things together - that the laws of physics are the same in every reference frame, and that it's a law of physics that light moves with certain velocity, you come to the conclusion that light must move with the same velocity in every reference frame. Why? Because the principle of relativity says that the laws of physics are the same in every reference frame, and Einstein announced that it is a law of physics that light moves with a certain velocity." https://youtu.be/toGH5BdgRZ4?t=626

Premise 1: The laws of physics are the same in every inertial frame (principle of relativity).

Premise 2: Maxwell said that the speed of light is a law of physics.

Conclusion: The speed of light is the same in every inertial frame:

John Norton: "Why Einstein should believe the light postulate is a little harder to see. We would expect that a light signal would slow down relative to us if we chase after it. The light postulate says no. No matter how fast an inertial observer is traveling in pursuit of the light signal, that observer will always find the light signal to be traveling at the same speed, c. [...] For Maxwell, that speed was always the same in just one frame of reference, the rest frame of his electromagnetic ether. The principle of relativity assured Einstein that the laws of nature were the same for all inertial observers. That light always propagated at the same speed was a law within Maxwell's theory. If it held in one inertial frame of reference, it must hold in all. So, if the principle of relativity was applied to Maxwell's law about light, the light postulate resulted immediately." https://www.pitt.edu/~jdnorton/teach...les/index.html
