In response to Berry Veroude:

...so that you have the inside centrifugal attraction of the black hole,
and the outer edged centripetal repulsion (dark matter?) occurring
simultaneously. To me, that makes sense.

I think, but i'm no expert that energie and mass when they are the same they will make dark energy by an exploding star. When a star explodes the heat and the explosion causing a lot of friction the friction causing an outpushing energy (they push out the dust and rocks) then when the power of the explosion is weaker in the center it turns the friction to rotate back causing an black hole, it is pushing everything in it's center causing a black hole, maybe it rotates so fast that it is pushing everything out. I know i read to much comics but my fantasy took me away listening and watching this video :-)
