• No Effects of Space Expansion Directly Observed

    Cosmologists interpret the Hubble redshift as evidence that space is expanding, although even Hubble did not believe this:

    "Reber (1982) pointed out that Hubble himself was never an advocate for the expanding universe idea. Indeed, it was Hubble who personally thought that a model universe based on the tired-light hypothesis is more simple and less irrational than a model
    universe based on an expanding spacetime geometry...any photon gradually loses its energy while traveling over a large distance in the vast space of the universe." Wilfred H. Sorrell, Misconceptions about the Hubble recession law, Astrophysics and Space
    Science, Sep 2009 http://paperity.org/p/19837385/misconceptions-about-the-hubble-recession-law

    Dec. 14, 1936: "Other causes for the redshift were suggested, such as cosmic dust or a change in the nature of light over great stretches of space. Two years ago Dr. Hubble admitted that the expanding universe might be an illusion, but implied that this
    was a cautious and colorless view. Last week it was apparent that he had shifted his position even further away from a literal interpretation of the redshift, that he now regards the expanding universe as more improbable than a non-expanding one." https:/

    Leaving aside the controversial interpretation of the Hubble redshift as evidence for space expansion, the effects of the expansion have never been directly observed. No observation has ever shown that a length or a distance between any two things has
    been stretched by space expansion.

    Cosmologists are plagued by actual or anticipated questions like

    If the universe is expanding, then why aren't we, why no length has been observed to stretch, why no two things have been observed to move apart pushed by expansion, etc.

    Cosmologists have alleviated the problem by tweaking the theory. Our theory predicts expansion, cosmologists have decided, only for pure voids - so the annoying questions become pointless. For spaces where stretching or moving apart is observable and the
    annoying questions are relevant, our theory predicts no expansion at all:

    Sabine Hossenfelder: "If The Universe Is Expanding, Then Why Aren't We? 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...It is only somewhere beyond the scales of galaxy
    clusters that expansion takes over." https://www.forbes.com/sites/startswithabang/2017/07/28/most-things-dont-actually-expand-in-an-expanding-universe/

    "Space DOES NOT Expand Everywhere...Is the space inside, say, a galaxy growing but overcome by the gravitational attraction between the stars? The answer is no. Space within any gravitationally bound system is unaffected by the surrounding expansion...In
    fact, the spacetime inside the Milky Way doesn't even know that the universe is expanding." https://youtu.be/bUHZ2k9DYHY?t=356

    "No experiment has ever been performed that verifies that expanding space can indeed alter the wavelength of an already moving photon." https://youtu.be/94_3N7XZjBQ?t=349

    No length or distance between any two objects has ever been observably altered, and the only reasonable conclusion is that...space is not expanding!
