    Black holes were popularized by television and movies beginning in the 1960's. Einstein repeatedly said that they cannot exist. He wrote in 1939 -
    "The essential result of this investigation is a clear understanding as to why the Schwarzchild singularities (Schwarzchild was the first to raise the issue of General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star) whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. And this is due to the fact that otherwise the constituting particles would reach the velocity of light".
    He was referring to dilation. It's the phenomenon our high school teachers were talking about when they said "mass becomes infinite at the speed of light". This doesn't mean mass increases, it means mass becomes spread throughout spacetime relative to an outside observer. Time dilation is just one aspect of dilation. Even mass that exists at 75% light speed is partially dilated.
    It occurs wherever there is an astronomical quantity of mass. This includes the centers of very high mass stars and the overwhelming majority of galaxy centers.
    The mass at the center of our own galaxy is dilated. This means that there is no valid XYZ coordinate we can attribute to it, you can't point your finger at something that is smeared through spacetime. In other words that mass is all around us. Sound familiar? This is the explanation for dark matter/galaxy rotation curves. The "missing mass" is dilated mass.
    Dilation does not occur in galaxies with low mass centers because they do not have enough mass to achieve relativistic velocities. It has been confirmed in 6 ultra diffuse galaxies including NGC 1052-DF2 and DF4 to have no dark matter. In other words they have normal rotation rates.

      If you wanted to write me a script for the next Physics Phriday I wouldn't be opposed lol. That's actually really neat though - thanks for all the extra info!

      Thanks, I think the concept of singularities is preventing clarity in physics. Relativity does not predict them when you factor in dilation. Nobody believed in them when Einstein was alive including Plank, Bohr, Schrodinger, Dirac, Heisenberg, Pauli, etc. There is no Schwarzchild radius according to Schwarzchild. He was publicly corrected and knew he was wrong.
      What we see in modern astronomy has been known since 1925. This is when the existence of galaxies was confirmed. It was clear that there should be an astronomical quantity of light emanating from our own galactic center.
      The modern explanation is because gravitational forces are so strong there that not even light can escape, even though the mass of the photon is zero. The correct explanation is because the mass there is dilated relative to an Earthbound observer.
