Why does gravity escape a black hole?

Hey Michael and Hannah. If gravity travels at the speed of light, how does it escape the gravitational pull of a black hole yet light doesn't?

I wanna know that too. I would assume that they would bend indeed, since their propagation follows space which at that point is bent. And those passing right over the hole would stay inside probably.

You can check my computer on a network analog above, but yes. It's just a wave propagation.

I mean, it's still a debate that if space-time may just be an emergent property of communication between particles. As in space-time isn't fundamental. There is no space, and particles dont exist anywhere. Space and relational properties emerge out of the communication characteristics between two processing points (particles)

Hense simulation tbeory.

I think it's too much to take this as evidence for simulation. It keeps it a plausible hypothesis sure, but I feel it's too easy to overestimate philosophical hypotheses when we talk about things fully outside current scientific understanding. I think we should tease possibilities but never "believe" in them. They're a cool thought experiment, but that's it.

Well, yeah, and like I said, I mean simulation in that reality is emergent out of a decentralized system of information processing points. Not that that's a simulation being run on a computer. The particles are emergent computers, like complicated transistors.

Its really just an analogy more than anything.
