    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.

    Great video. Peace 😎 ✌️ from Canada, eh.

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