Yes. I've heard that one so often, but no one I know of who advocates that idea can give an answer to my question of why are there black holes of a wide range of mass, from stellar-sized up to super and hyper-massive. It only makes sense if black holes accumulate the mass that falls into them, rather than expel it "somewhere else".

@OldDave They accumulate gravitons perhaps the magnetic force is to grate to let much of the debris expel something like a tornado without external forces working on then like in an atmosphere.

@azzow2 do you know anything about physics?
