• The Fundamental Axiom of Einstein-Free Physics

    From Pentcho Valev@21:1/5 to All on Wed May 3 02:59:08 2023
    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

    Feynman's words, if taken at face value, imply that the concept of VARIABLE wavelength of light

    https://www.youtube.com/watch?v=xsVxC_NR64M

    is unrealistic. Actually, a lot of evidence suggests that the wavelength of light depends only on the nature of the emitting substance and is constant otherwise.

    "The wavelength of light is constant" will become the fundamental axiom of future, Einstein-free physics. Here are some corollaries:

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

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

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

    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.

    Corollary 5: The so-called cosmological (Hubble) redshift is due to the speed of light gradually slowing down as light travels through vacuum, in a non-expanding universe.

    Corollary 6: The dark sky in the Olbers' paradox can be explained by two facts. 1. Low-speed, high-redshifted light (known as CMB), coming from very distant sources, is invisible. 2. Beyond a certain distance, the star light does not reach us at all (its
    speed is reduced to zero).

    If the speed of light is constant as per Einstein, then ANY frequency shift entails (is caused by) an inversely proportional wavelength shift, in accordance with the formula

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

    In the Doppler-moving-observer scenario, there is frequency shift without wavelength shift, which suggests that the wavelength may remain constant in other scenarios as well and proves that the speed of light is variable, not constant:

    "Thus, the moving observer sees a wave possessing the same wavelength...but a different frequency...to that seen by the stationary observer." http://farside.ph.utexas.edu/teaching/315/Waveshtml/node41.html

    Max Planck Institute for Gravitational Physics: "You can see for yourself that, once more, there is a blue-shift - the pulse frequency measured at the receiver is somewhat higher than the frequency with which the pulses are sent out. This time, the
    distances between subsequent pulses are not affected, but still there is a frequency shift." https://www.einstein-online.info/en/spotlight/doppler/

    "Vo is the velocity of an observer moving towards the source. This velocity is independent of the motion of the source. Hence, the velocity of waves relative to the observer is c + Vo...The motion of an observer does not alter the wavelength. The
    increase in frequency is a result of the observer encountering more wavelengths in a given time." http://a-levelphysicstutor.com/wav-doppler.php

    "The Doppler effect is the shift in frequency of a wave that occurs when the wave source, or the detector of the wave, is moving. Applications of the Doppler effect range from medical tests using ultrasound to radar detectors and astronomy (with
    electromagnetic waves)...Moving Observer. Let's say you, the observer, now move toward the source with velocity Vo. You encounter more waves per unit time than you did before. Relative to you, the waves travel at a higher speed: V' = V+Vo. The frequency
    of the waves you detect is higher, and is given by: f' = V'/λ = (V+Vo)/λ." http://physics.bu.edu/~redner/211-sp06/class19/class19_doppler.html

    Light emitted is just "free energy".

    It's not free in the sense of cost-less or unbounded,
    just free in the sense of "least action applies".

    Besides what's emitted and reflected, or absorbed,
    is basically about that "seconds per meter" is constant
    instead of "meters per second".

    Anyways if you don't know particle-wave duality, and, photon
    being a wave-packet, and, this kind of thing, and that light in the
    visible is special and falls in empty space, is probably for making light
    and radiation like weak and nuclear force and radiation, about those
    being complements and having the kind of theory where:
    mass and charge are the quantities
    emission and transmutation are the quantities
    that then you'd have more ideas about the
    "slow" and "fast" types of these thing, in terms
    of light speed, proton lifetime, iron half-life,
    how many balloons it takes to float a cat,
    these kinds of things.

    Yeah, even people who know "mass and charge are fundamental,
    it's energy", don't think much about "light as free and matter as fixed".

    Necessarily, ....

    Why are people always forgetting the weak/electroweak nuclear force, ....

    Speed and frequency vary proportionally as light falls in a gravitational field:

    University of Illinois at Urbana-Champaign: "Consider a falling object. Its speed increases as it is falling. Hence, if we were to associate a frequency with that object the frequency should increase accordingly as it falls to earth. Because of the
    equivalence between gravitational and inertial mass, we should observe the same effect for light. So lets shine a light beam from the top of a very tall building. If we can measure the frequency shift as the light beam descends the building, we should be
    able to discern how gravity affects a falling light beam. This was done by Pound and Rebka in 1960. They shone a light from the top of the Jefferson tower at Harvard and measured the frequency shift. The frequency shift was tiny but in agreement with the
    theoretical prediction." https://courses.physics.illinois.edu/phys419/sp2011/lectures/Lecture13/L13r.html

    James Hartle, Gravity: An Introduction to Einstein's General Relativity, p. 113: "If we accept the equivalence principle, we must also accept that light falls in a gravitational field with the same acceleration as material bodies." https://www.amazon.com/
    Gravity-Introduction-Einsteins-General-Relativity/dp/0805386629

    Paul A. Tipler, Ralph A. Llewellyn, Modern Physics: "But according to the equivalence principle, there is no way to distinguish between an accelerating compartment and one with uniform velocity in a uniform gravitational field. We conclude, therefore,
    that A BEAM OF LIGHT WILL ACCELERATE IN A GRAVITATIONAL FIELD AS DO OBJECTS WITH REST MASS. For example, near the surface of Earth light will fall with acceleration 9.8 m/s^2." http://web.pdx.edu/~pmoeck/books/Tipler_Llewellyn.pdf

    But if speed of light and frequency vary proportionally, the wavelength of light remains constant, in accordance with the formula

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

    Modern physics teaches that light waves, like sound or water waves, bunch up in front of the moving emitter:

    "The wavefronts will bunch up (get closer together) in front of the source as it travels and will be spaced out (further apart) behind it." https://theconversation.com/explainer-the-doppler-effect-7475

    https://www.youtube.com/watch?v=3mJTRXCMU6o&t=77s

    Bunching up is realistic for sound and water waves but in the case of light it is a preposterous concept that contradicts the principle of relativity. If the light waves bunched up in front of the emitter, the emitter could regularly measure the
    wavelength variations inside his spaceship - so he would know his spaceship's speed without looking outside. If, for instance, measurements inside the spaceship show that the wavelength has decreased, the emitter will conclude that his spaceship is now
    moving faster than before.

    Some theoreticians see the absurdity and try to camouflage it by declaring that bunching up is actual only for the observer (receiver). For the emitter it does not exist - the wavelength remains constant for him. This is idiocy of course but still there
    is a valuable truth in it. Yes, the wavelength leaves the emitter constant, independent of the emitter's speed.
