This makes no sense. If we are below the event horizon, how come we aren't ripped apart by gravitational forces?
Event horizons are independent of any gravitational "force". Around a Solar mass black hole, the tidal forces in the region of the event horizon would be enormous, but this is by no means always the case. Around a hypermassive black hole, the tidal forces at the horizon could be unnoticeable.
Nothing in here makes any sense. Do you even understand what a black hole is?
The black hole in this case is significantly different to the normal layman presentation of a black hole. "this makes no sense" is typically not a good defence against the physics of General Relatvity... very little of it makes sense!
But don't worry, Humphrey's interpretation of his model IS nonsense and hopefully I'll get to some of it before the end of the evening.
