Brian Greene: What does it mean for the speed of light to be constant? https://www.youtube.com/watch?v=-Irlq3TFr8Q
Brian Cox p. 91: "...Maxwell's brilliant synthesis of the experimental results of Faraday and others strongly suggested that the speed of light should be the same for all observers. This conclusion was supported by the experimental result of Michelson and Morley, and taken at face value by Einstein." http://www.amazon.com/Why-Does-mc2-S.../dp/0306817586 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 Two educational lies without which Einstein's relativity would be long forgotten: 1. Maxwell's 19th century theory showed that the speed of light is the same for all observers. 2. The Michelson-Morley experiment showed that the speed of light is the same for all observers.

Neil deGrasse Tyson: "One of the towering great achievements of the human mind in our understanding of the universe is Einstein's theories of relativity. [...] It makes only two assumptions: that the speed of light in a vacuum is constant no matter who is doing the measurement and no matter in what direction you are moving or how fast. You always get the same measurement for the speed of light. That's Assumption 1 which by the way the experiment has shown to be true. [...] Given those two tenets, extraordinary spooky phenomena derive from them. For example: As you travel faster [...] time ticks more slowly for you than it does for other people..." https://www.youtube.com/watch?v=n2s1-RHuljo
Two lies he Lie 1: "You always get the same measurement for the speed of light. That's Assumption 1 which by the way the experiment has shown to be true." Any relevant experiment (e.g. Michelson-Morley, Pound-Rebka, Doppler), if correctly performed and interpreted, proves VARIABLE speed of light as per Newton's theory: John Norton: "The Michelson-Morley experiment is fully compatible with an emission theory of light that CONTRADICTS THE LIGHT POSTULATE." http://philsci-archive.pitt.edu/1743/2/Norton.pdf "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 Lie 2: "As you travel faster [...] time ticks more slowly for you than it does for other people..." If logic is obeyed, special relativity says the opposite. The conclusion that validly follows from Einstein's 1905 postulates is As you travel faster time ticks FASTER for you than it does for other people. David Morin, Introduction to Classical Mechanics With Problems and Solutions, Chapter 11, p. 14: "Twin A stays on the earth, while twin B flies quickly to a distant star and back. [...] For the entire outward and return parts of the trip, B does observe A's clock running slow..." http://www.people.fas.harvard.edu/~djmorin/chap11.pdf "The situation is that a man sets off in a rocket travelling at high speed away from Earth, whilst his twin brother stays on Earth. [...] ...the twin in the spaceship considers himself to be the stationary twin, and therefore as he looks back towards Earth he sees his brother ageing more slowly than himself." http://topquark.hubpages.com/hub/Twin-Paradox Pentcho Valev |

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 in the interpretation of the Doppler effect that saves Einstein's relativity. Here the initially stationary receiver (observer) starts moving towards the light source with speed v: http://www.einstein-online.info/imag...ector_blue.gif If you are an Einsteinian and wish most of all the speed of the light pulses relative to the receiver to remain unchanged, you should idiotically believe that the motion of the receiver changes the distance between incoming pulses - from d to d'=dc/(c+v). Equally idiotically, the motion of the receiver changes the wavelength of the incoming light - from λ to λ'=λc/(c+v). Needless to say, the motion of the receiver (observer) CANNOT change the wavelength of the incoming light. The fudge factor is too idiotic, even for the standards of Einstein's schizophrenic world, so it is kept hidden in Einstein's "theory" - Einsteinians don't discuss it explicitly. Here are exceptions (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 Pentcho Valev |
