>the size of a black hole (some bigger than out entire solar system) is literally just the empty space beyond the event horizon

For some weird reason i always assumed the mass of a black hole is also defined by some sort of material, but it all is focused in the singularity at the center. So every black hole in theory has the same "size", the singularity. What differs is how far the event horizon stretches out?
>>
The black hole is literally just empty space bounded by the event horizon with all the 9000 suns crammed in the singularity (a single point with no volume) in the center.

>with no volume
What makes the event horizon stretch out? The masses in the infinite process of falling in stretching out far out the black hole branches out?

There is no singularity retard

Right, its your mum's asshole lol

Huh, sorry what? I was busy staring at tits.

So empty space with 9000 suns in it. Ok

You don’t know what an event horizon is, do you?

Singularities are mathematical concepts inside mathematical models. They may not exist in real life despite what scientists on TV say. The black hole itself is a star with extreme density in an unknown state of matter

>What makes the event horizon stretch out?
The horizon is just a boundary. It's not a physical thing. The centre of a black hole is just a really dense star. Like any celestial object, it has escape velocity. But for a black hole the escape velocity is over the speed of light. The event horizon is just the boundary where the escape velocity is the speed of light. So any light emitted by the star just falls back in and can't escape
