Want to correct/clarify one thing as I’m watching: around 4:20 she mentions that the Schwarzild solution is for a point mass. It’s actually a bit more general. The solution applies at the vacuum for any spherically symmetric system (in 3-space). The “mass” doesn’t have to be a point source for the solution to work outside the body where the energy level is 0. The solution, for example, works outside the earth (but not inside). The black hole prediction is if you can squeeze this mass body into a sufficiently small space such that the event horizon manifests.

There is no black holes. General Relativity predicts dilation, not singularities. In the 1939 journal "Annals of Mathematics" Einstein 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 General Relativity predicting singularities) do not exist in physical reality. Although the theory given here treats only clusters (star 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. It's the phenomenon behind the phrase "mass becomes infinite at the speed of light". Time dilation is one aspect of dilation. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum. Dilation is the original and correct explanation for why we cannot see light from the galactic center. It can be shown mathematically that the mass at the center of our own galaxy must be dilated. In other words that mass is all around us. Sound familiar? This is the explanation for dark matter, the "missing mass" is dilated mass. Einstein wrote about dilation occuring in "large clusters of stars" which is basically a very low mass galaxy. For a galaxy to have no/low dilation it must have very, very low mass. It has recently been confirmed in 5 very, very low mass galaxies to show no signs of dark matter.

Great video. Peace 😎 ✌️ from Canada, eh.

Nice thumbnail..

Maybe black holes are à dynamos to provide energy for the dark matter.

Pulp science. Barf
