Black Hole Cores in Active Galaxies: A Simple Argument

READ: This was not meant to be a video originally, I was just playing with my cam, and it ended up turning out decent (besides my horrible writing). I decided to post it to see what people thought and maybe (if you guys like) will post more in the future that is more legible.

Details:
Just a very simple physics argument, for those with basic physics, that explains why there exists a supermassive black hole at the center of each active galaxy. Based on the principle that energy going in must equal energy going out due to the stability of the core of galaxies. This is NOT meant to be very formal (or complex) proof as to why, this is merely meant for a really interesting argument that physicists came up with when they first started trying to understand active galaxies.

The argument logic:
Energy emitted from inside the core = Energy from mass falling into the core

The result:
The energy emitted from the core is maximized when the mass is large relative to the radius. Since black holes are the most compact objects in the universe, this leads us to believe that the object that is releasing tons of radiation in the center of these active galaxies must be a black hole. A very simple argument and conclusion.


P.S. Sorry for the horrible writing, this is my first video ever so maybe if I ever decide to make more, I'll improve in that aspect.

Thanks!
