Does gravity travel instantanious, or does it travel at a certain speed. And can you detect what is inside a black hole, or at least the mass distribution, by measuring the gravity of the hole? What if you drop something into the hole and measures its position by the use of its gravity? what will then be detected? That the object has the same position as is given by the light emitted by the object and the object being "freezed" on the event horizon, or will something else be detected, for instance the objects position inside the event horizon.

If gravity travels with a finite speed, can there exist a gravity field so strong, that gravity can't escape, and what happens then?
