Default Constant Speed of Light: the Root of All the Evil in Physics

The speed of light is obviously variable so it is not easy to convince students that it is constant:

Joe Wolfe: "At this stage, many of my students say things like "The invariance of the speed of light among observers is impossible" or "I can't understand it". Well, it's not impossible. It's even more than possible, it is true. This is something that has been extensively measured, and many refinements to the Michelson and Morley experiment, and complementary experiments have confirmed this invariance to very great precision. As to understanding it, there isn't really much to understand. However surprising and weird it may be, it is the case. It's the law in our universe. The fact of the invariance of c doesn't take much understanding." https://newt.phys.unsw.edu.au/einste...eird_logic.htm

Neil deGrasse Tyson's "cosmic conspiracy of the highest order" - the triumph of post-truth (post-sanity) education:

Neil deGrasse Tyson, Death by Black Hole: And Other Cosmic Quandaries, pp. 123-124: "If everyone, everywhere and at all times, is to measure the same speed for the beam from your imaginary spacecraft, a number of things have to happen. First of all, as the speed of your spacecraft increases, the length of everything - you, your measuring devices, your spacecraft - shortens in the direction of motion, as seen by everyone else. Furthermore, your own time slows down exactly enough so that when you haul out your newly shortened yardstick, you are guaranteed to be duped into measuring the same old constant value for the speed of light. What we have here is a COSMIC CONSPIRACY OF THE HIGHEST ORDER." https://www.amazon.com/Death-Black-H.../dp/039335038X

Brian Greene: "Einstein proposed a truly stunning idea - that space and time could work together, constantly adjusting by exactly the right amount so that no matter how fast you might be moving, when you measure the speed of light it always comes out to be 671000000 miles per hour." https://www.youtube.com/watch?v=dc3-29dguFs

Michelle Thaller (52:06): "The speed of light is so constant that the universe actually changes everything so that you never see it going any other speed" https://youtu.be/fiv7qUQ51Kc?t=3126

Robert Scherrer: "In fact, the laws for adding and subtracting speeds have to conspire to keep the speed of the light the same no matter how fast or in what direction an observer is moving. The only way to make this happen is for space and time to expand or contact as objects move." http://www.cosmicyarns.com/2015/04/s...eed-limit.html

Brian Greene: "If space and time did not behave this way, the speed of light would not be constant and would depend on the observer's state of motion. But it is constant; space and time do behave this way. Space and time adjust themselves in an exactly compensating manner so that observations of light's speed yield the same result, regardless of the observer's velocity." http://www.pbs.org/wgbh/nova/physics...-nutshell.html

Musical brainwashing:

Lisa Randall, Michio Kaku, Brian Cox, Neil deGrasse Tyson, Brian Greene: "Light travels at the same speed no matter how you look at it. No matter how I move relative to you light travels at the same speed. No matter who is doing the measurement and no matter what direction you are moving the speed of light is the same. The speed of light is the same no matter what direction or how fast... As you travel faster time slows down. Everything slows down. Everything slows down. Time slows down when you move. Time passes at a different rate. Clocks run slow. It's a monumental shift in how we see the world. It's a beautiful piece of science. It's a beautifully elegant theory. It's a beautiful piece of science. It's a beautiful piece..." https://www..youtube.com/watch?v=BuxFXHircaI

Constancy of the speed of light - the nonsense on which the whole fundamental physics is based - is imposed on physics students in the same way as the name Bingo is imposed on the dude in this video:

Bingo the Clowno https://www.youtube.com/watch?v=4kACHU5eSwQ&t=78s

In the end each student gets the name Bingo the Einsteiniano.
