  • Nonexpanding Universe, Redshift and...Crimestop

    From Pentcho Valev@21:1/5 to All on Wed Mar 2 15:47:27 2022
    "The Universe is not expanding at all...the redshift of light with increasing distance must be caused by some other phenomena – something that happens to the light itself as it travels through space." http://sci-news.com/astronomy/science-universe-not-
    expanding-01940.html

    What happens to light as it travels through space? Can it be slowed down (the redshift with increasing distance would be a direct corollary)? Yes light CAN be slowed down inside vacuum but...theoretical physicists are in crimestop mode:

    "Physicists manage to SLOW DOWN LIGHT INSIDE VACUUM [...] ...even now the light is no longer in the mask, it's just the propagating in free space - the speed is still slow. [...] "This finding shows unambiguously that the propagation of light can be
    slowed below the commonly accepted figure of 299,792,458 metres per second, even when travelling in air or vacuum," co-author Romero explains in the University of Glasgow press release." http://rt.com/news/225879-light-speed-slow-photons/

    "Some physicists, however, suggest that there might be one other cosmic factor that could influence the speed of light: quantum vacuum fluctuation. This theory holds that so-called empty spaces in the Universe aren't actually empty - they're teeming with
    particles that are just constantly changing from existent to non-existent states. Quantum fluctuations, therefore, could slow down the speed of light." https://www.sciencealert.com/how-much-do-we-really-know-about-the-speed-of-light

    George Orwell: "Crimestop means the faculty of stopping short, as though by instinct, at the threshold of any dangerous thought. It includes the power of not grasping analogies, of failing to perceive logical errors, of misunderstanding the simplest
    arguments if they are inimical to Ingsoc, and of being bored or repelled by any train of thought which is capable of leading in a heretical direction. Crimestop, in short, means protective stupidity."

    The universe is not expanding. If it were, the competition between expansion and gravitational attraction would distort galaxies and galactic clusters - e.g. fringes only weakly bound by gravity would succumb to expansion and fly away. No distortions
    observed.

    Sabine Hossenfelder: "The solution of general relativity that describes the expanding universe is a solution on average; it is good only on very large distances. But the solutions that describe galaxies are different - and just don't expand. It's not
    that galaxies expand unnoticeably, they just don't. The full solution, then, is both stitched together: Expanding space between non-expanding galaxies." http://backreaction.blogspot.bg/2017/08/you-dont-expand-just-because-universe.html

    "Expanding space between non-expanding galaxies" is absurd of course, but in Hossenfelder's text part of the absurdity is omitted. What the Einsteinian cosmology actually assumes, implicitly, is

    "Expanding space between non-expanding galactic clusters."

    Super absurd, isn't it?

    The idea that vacuum slows down light is largely discussed but only in terms of quantum gravity. The implication that the Hubble redshift might be due to gradually decreasing speed of starlight is persistently ignored (crimestop):

    "...in some quantum-gravity models, the speed of photons in gamma rays would be affected by the grainy nature of spacetime..." https://fqxi.org/community/articles/display/255

    Sabine Hossenfelder: "It's an old story: Quantum fluctuations of space-time might change the travel-time of light. Light of higher frequencies would be a little faster than that of lower frequencies. Or slower, depending on the sign of an unknown
    constant. Either way, the spectral colors of light would run apart, or 'disperse' as they say if they don't want you to understand what they say. Such quantum gravitational effects are miniscule, but added up over long distances they can become
    observable. Gamma ray bursts are therefore ideal to search for evidence of such an energy-dependent speed of light." http://backreaction.blogspot.fr/2017/01/what-burst-fresh-attempt-to-see-space.html

    Nature: "As waves travel through a medium, they lose energy over time. This dampening effect would also happen to photons traveling through spacetime, the researchers found. Although the effect is small, high-energy photons traveling very long distances
    should lose a noticeable amount of energy, the researchers say. [...] If it is true that spacetime is a superfluid and that photons of different energies travel at different speeds or dissipate over time, that means relativity does not hold in all
    situations." http://www.nature.com/news/superfluid-spacetime-points-to-unification-of-physics-1.15437

    Reading the usual lies from relativists about experiments that “confirm” relativity.
    Ie the Lunar ranging experiment. Apparently after taking into account libration, time
    delays from earths atmosphere etc, the simple formula used by relativists is:
    (speed of light × duration of delay due to reflection) / 2...)

    Sounds like the same formula is used by a classical non relativistic model. Seeing as the laser light source is in the same frame as the frame of the observer making the measurements of the return flight time of the laser pulse in the lunar ranging experiments.
    Which as we all know is also the same prerequisite for a non relativistic classical
    model. Which is that in a classical model the speed of light is also always predicted to be at c in the source frame. As is confirmed by the lunar ranging experiment.
