Default Einstein: The Speed of Light Is a Law of Physics

Here https://bartleby.com/173/7.html Einstein advances an idiotic premise: c = 300,000 km/sec is a law of physics.

The idiotic consequence: c â‰* 300,000 km/sec "comes into conflict" with the principle of relativity (which says the laws of physics are the same in every inertial frame):

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..prince.../vol6-trans/16

The most idiotic syllogism in human history:

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
