How Stars Die

What happens to a star when it can no longer do nuclear fusion? It ends up as a white dwarf, a neutron star, or a black hole.
For more information, I recommend the following books:
Stellar Evolution and Nucleosynthesis by Ryan and Norton
Stellar Interiors by Hansen, Kawaler, and Trimble
Stars and Stellar Evolution by De Boer and Seggewiss
Stellar Structure and Evolution by Kippenhahn, Weigert, and Weiss

@@ItsJustAstronomical I really love how creative and succinct your videos are. Perfect blend of intuitive visuals and mind boggling physical phenomena!

Black holes are based on a mathematical misconception. 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 G.R. 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 just one aspect of dilation, it's not just time that gets dilated. Dilation will occur wherever there is an astronomical quantity of mass because high mass means high momentum.
There is no singularity at the center of our galaxy. It can be inferred mathematically that dilation is occurring there. This means that 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. More precisely, everywhere you point is equally valid. In other words that mass is all around us. This is the explanation for galaxy rotation curves/dark matter. 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 very low mass galaxies including NGC 1052-DF2 and DF4 to have no dark matter.
There can only be clarity in astronomy if the concept of singularities is discarded. Einstein is known to have repeatedly said that they cannot exist. Nobody believed in them when he was alive including Planck, Bohr, Dirac, Schrodinger, Heisenberg, Feynman etc.

Tks 4 the correction !
