Hi, my first post here!(adsbygoogle = window.adsbygoogle || []).push({});

Galaxies outside the observable universe (that we can't see their light) can affect us with their gravity?

If the answer is no, we can say that gravity information travels at the speed of light.

So, in a black hole how gravity information from an object inside, escapes the event horizon?

An object inside a black hole is also outside our observable universe.

I know that in general relativity mass of a black hole is responsible for the curvature of spacetime, but where this curvature begins in our universe? Does it begin from the Event Horizon limit? Can we say the event horizon itself carries all the gravity information of a black hole?

I can't figure it out, I have it, all in a mess inside my mind
