• Richard Feynman: Light Is Made of Particles

    From Pentcho Valev@21:1/5 to All on Tue Jul 27 14:52:29 2021
    Richard Feynman: "I want to emphasize that light comes in this form - particles. It is very important to know that light behaves like particles, especially for those of you who have gone to school, where you probably learned something about light
    behaving like waves. I'm telling you the way it does behave - like particles. You might say that it's just the photomultiplier that detects light as particles, but no, every instrument that has been designed to be sensitive enough to detect weak light
    has always ended up discovering the same thing: light is made of particles." QED: The Strange Theory of Light and Matter p. 15 https://www.amazon.com/QED-Strange-Theory-Light-Matter/dp/0691024170

    Banesh Hoffmann, Einstein's collaborator, admits that, originally ("without recourse to contracting lengths, local time, or Lorentz transformations"), the Michelson-Morley experiment directly proved Newton's variable speed of light and disproved the
    constant speed of light:

    "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." Banesh Hoffmann, Relativity and Its Roots, p.92 https://www.amazon.

    Wikipedia tells the truth about the Michelson-Morley experiment here (elsewhere it says the opposite):

    "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

    Feynman UNWITTINGLY suggests that variable wavelength of light (see https://youtube.com/watch?v=xsVxC_NR64M) is an unrealistic concept. Actually, it contradicts the principle of relativity. If the wavelength (distance between light pulses) varied with
    the speed of the emitter, the emitter would measure it inside his spaceship and so would know his speed without looking outside.

    The formula

    (frequency) = (speed of light)/(wavelength)

    tolerates two axioms:

    Axiom 1: The speed of light is constant.

    Axiom 2: The wavelength of light is constant (for a given emitter).

    Axiom 1 killed physics.

    Axiom 2 will resurrect it (if it's not too late). Corollaries:

    Corollary 1: Any frequency shift entails (is caused by) a proportional speed-of-light shift.

    Corollary 2: If the emitter and the observer (receiver) travel towards each other with relative speed v, the speed of light as measured by the observer is c' = c+v, as per Newton's theory.

    Corollary 3: Spacetime and gravitational waves (ripples in spacetime) don't exist. LIGO's "discoveries" are fake.

    Corollary 4: Light falls in a gravitational field with the same acceleration as ordinary falling bodies - near Earth's surface the accelerations of falling photons is g = 9.8 m/s^2. Accordingly, there is no gravitational time dilation: Einstein's general
    relativity is absurd.

    Corollary 5: The Hubble redshift is due to light slowing down as it travels through vacuum. The universe is not expanding.
