Default Explaining Einstein's Constant-Speed-of-Light Nonsense

Lee Smolin: "Why does light have a constant speed? Why does it have the same speed in all reference frames? That's one of the principles of special relativity. Therefore it's unexplained. It's something which Einstein assumed and which we assume and which leads to consequences which agree with experiments. You are not satisfied with that and you are looking for an explanation." https://youtu.be/Zri9gS1w5ok?t=4785

The constancy of the speed of light cannot be explained because it is nonsense. Even Einstein knew that:

John Stachel: "But this seems to be nonsense. How can it happen that the speed of light relative to an observer cannot be increased or decreased if that observer moves towards or away from a light beam? Einstein states that he wrestled with this problem over a lengthy period of time, to the point of despair." http://www.aip.org/history/exhibits/...relativity.htm

Accurate presentation of Einstein's 1905 nonsensical axiom:

Brian Greene: What does it mean for the speed of light to be constant? https://www.youtube.com/watch?v=-Irlq3TFr8Q

Space and time were vandalized accordingly - to fit the nonsensical constancy - and physics died (became insane):

"Special relativity is based on the observation that the speed of light is always the same, independently of who measures it, or how fast the source of the light is moving with respect to the observer. Einstein demonstrated that as an immediate consequence, space and time can no longer be independent, but should rather be considered a new joint entity called "spacetime." http://community.bowdoin.edu/news/20...rs-of-gravity/

Joe Wolfe is honest in a sense:

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

Default Explaining Einstein's Constant-Speed-of-Light Nonsense

Kip Thorne (4:56): "If you move toward the source [of light], you see the wavelength shortened, but you don't see the speed changed." https://youtu.be/mvdlN4H4T54?t=296

"The wavelength shortened" is an idiotic fudge factor that preserves the constancy of the speed of light and saves Einstein's relativity.

The observer (receiver) starts moving towards the light source with speed v:

If you are an Einsteinian and your entire life depends on the constancy of the speed of light, you should believe or pretend to believe, like Kip Thorne, that the motion of the observer changes the distance between incoming pulses - from d to d'=dc/(c+v). Equivalently, you should believe that the motion of the observer changes the wavelength of the incoming light - from λ to λ'=λc/(c+v).

Needless to say, the motion of the observer CANNOT change the wavelength of the incoming light. The fudge factor is too idiotic, even by the standards of Einstein cult, so Einsteinians don't discuss it explicitly. Still, even though swept under the carpet, the super idiotic fudge factor is a crucial prediction of Einstein's "theory".

Here are exceptions - Einsteinians who explicitly discuss the idiocy (these Einsteinians are particularly deranged and teach that the motion of the observer changes the wavelength even in the case of sound waves):

http://bretagnemontagne.files.wordpr...2011/02/23.jpg

Professor Martin White, UC Berkeley: "...the sound waves have a fixed wavelength (distance between two crests or two troughs) only if you're not moving relative to the source of the sound. If you are moving away from the source (or equivalently it is receding from you) then each crest will take a little longer to reach you, and so you'll perceive a longer wavelength. Similarly if you're approaching the source, then you'll be meeting each crest a little earlier, and so you'll perceive a shorter wavelength. [...] The same principle applies for light as well as for sound. In detail the amount of shift depends a little differently on the speed, since we have to do the calculation in the context of special relativity. But in general it's just the same: if you're approaching a light source you see shorter wavelengths (a blue-shift), while if you're moving away you see longer wavelengths (a red-shift)." http://w.astro.berkeley.edu/~mwhite/...plershift.html

John Norton: "Every sound or light wave has a particular frequency and wavelength. In sound, they determine the pitch; in light they determine the color. Here's a light wave and an observer. If the observer were to hurry towards the source of the light, the observer would now pass wavecrests more frequently than the resting observer. That would mean that moving observer would find the frequency of the light to have increased (and correspondingly for the wavelength - the distance between crests - to have decreased)." http://www.pitt.edu/~jdnorton/teachi...ved/index.html

Default Explaining Einstein's Constant-Speed-of-Light Nonsense

The speed of light is OBVIOUSLY VARIABLE:

Stationary light source, moving receiver: http://www.einstein-online.info/imag...ector_blue.gif

The speed of the light pulses as measured by the source is

c = df

where d is the distance between the pulses and f is the frequency measured by the source. The speed of the pulses as measured by the receiver is

c'= df' c

where f' f is the frequency measured by the receiver.

In the quotation below Banesh Hoffmann clearly explains that, "without recourse to contracting lengths, local time, or Lorentz transformations" (as was the case in 1887), the Michelson-Morley experiment proves Newton's variable speed of light (c'=c±v) and disproves the constant (independent of the speed of the emitter) speed of light (c'=c) posited by the ether theory and adopted by Einstein:

Banesh Hoffmann, Relativity and Its Roots, p.92: "Moreover, if light consists of particles, as Einstein had suggested in his paper submitted just thirteen weeks before this one, the second principle seems absurd: A stone thrown from a speeding train can do far more damage than one thrown from a train at rest; the speed of the particle is not independent of the motion of the object emitting it. And if we take light to consist of particles and assume that these particles obey Newton's laws, they will conform to Newtonian relativity and thus automatically account for the null result of the Michelson-Morley experiment without recourse to contracting lengths, local time, or Lorentz transformations. Yet, as we have seen, Einstein resisted the temptation to account for the null result in terms of particles of light and simple, familiar Newtonian ideas, and introduced as his second postulate something that was more or less obvious when thought of in terms of waves in an ether. If it was so obvious, though, why did he need to state it as a principle? Because, having taken from the idea of light waves in the ether the one aspect that he needed, he declared early in his paper, to quote his own words, that "the introduction of a 'luminiferous ether' will prove to be superfluous." https://www.amazon.com/Relativity-It.../dp/0486406768

Wikipedia: Newton's variable speed of light, c'=c ± v, explains the result of the Michelson-Morley experiment:

"Emission theory, also called emitter theory or ballistic theory of light, was a competing theory for the special theory of relativity, explaining the results of the Michelson–Morley experiment of 1887. [...] The name most often associated with emission theory is Isaac Newton. In his corpuscular theory Newton visualized light "corpuscles" being thrown off from hot bodies at a nominal speed of c with respect to the emitting object, and obeying the usual laws of Newtonian mechanics, and we then expect light to be moving towards us with a speed that is offset by the speed of the distant emitter (c ± v)." https://en.wikipedia.org/wiki/Emission_theory

In teaching Einstein's 1905 constant-speed-of-light nonsense Einsteinians know no limits:

Michelle Thaller: "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/IuKtXTOlADU?t=3487

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, 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

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

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 of 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

Eventually each student gets the name Bingo the Einsteiniano.

"In the end the Party would announce that two and two made five, and you would have to believe it. It was inevitable that they should make that claim sooner or later: the logic of their position demanded it. Not merely the validity of experience, but the very existence of external reality, was tacitly denied by their philosophy. The heresy of heresies was common sense. And what was terrifying was not that they would kill you for thinking otherwise, but that they might be right. For, after all, how do we know that two and two make four? Or that the force of gravity works? Or that the past is unchangeable? If both the past and the external world exist only in the mind, and if the mind itself is controllable what then?" https://ebooks.adelaide.edu.au/o/orw...hapter1.7.html
