    Well made video. There is an elephant in the room explanation for those abnormally high star rotation rates. It is the original, forgotten explanation for why we cannot see light from the galactic center. Most people don't know that Einstein said that singularities are not possible. In the 1939 journal "Annals of Mathematics" he wrote "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 GR predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters whose particles move along circular paths it does seem to be subject to reasonable doubt that more general cases will have analogous results. The Schwarzchild singularities do not appear for the reason that matter cannot be concentrated arbitrarily. And this is due to the fact that otherwise the constituting particles would reach the velocity of light."
    He was referring to the phenomenon of dilation (sometimes called gamma or y). Mass that is dilated is smeared through spacetime relative to an outside observer. This is illustrated in a common 2 axis relativity graph with velocity (from stationary to the speed of light) on the horizontal line and dilation/gamma/y on the vertical. The graph shows the squared nature of the phenomenon, dilation increases at an exponential rate the closer you get to the speed of light.
    Wherever you have an astronomical quantity of mass, dilation will occur because high mass means high momentum. There is no place in the universe where mass is more concentrated than at the center of a galaxy.
    General relativity does not predict singularities when you factor in dilation. Einstein is known to have repeatedly spoken about this. Nobody believed in black holes when he was alive for this reason.
    In the "Annals of Mathematics" Einstein spoke about dilation occurring in regions that would less mass than that which would exist at the center of common spiral galaxies. Therefore, it is safe to say that according to Einstein's math the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. You could use the same math to calculate the surface rotation of the sun if you doubled it's mass.
    The reason why we cannot see light from the galactic center is because there is no valid XYZ coordinate that we can attribute to it, you can't point your finger at something that is smeared through spacetime.
    According to Einstein's math, galaxies with very, very low mass will show no signs of dark matter because they do not have enough mass at the center to achieve relativistic velocities, therefore they are not infused with dilated mass. This has been confirmed by galaxy NGC 1052-DF2.
    A simple way to confirm this would be to calculate the star rotation rates of a large number of galaxies. This would show that all the high mass galaxies would have star rotation rates that defy the known laws of physics and all the low mass galaxies (some galaxies can appear to be low mass but can have high mass at the center) would have predictable star rotation rates.
