There are no black holes. Einstein 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. 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. 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 because high mass means high momentum. 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. 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 recently 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.
