If the event horizon of a black hole is defined as the region from which information cannot escape, then how can the black hole have gravity?
Wouldn't that count as information?
I know the event horizon forms because of gravity, but the definition itself would then not make sense

nothing "has gravity" in general relativity

Okay, how can it warp spacetime?
That counts as information, doesn't it?
Sending out gravitational waves

but everything has energy; and energy modifies the spacetime geometry to an extent that it acts like an apparent force

I thought no information in an event horizon can reach the outside world?
