If black holes are just regions of spacetime, where the slope of spacetime is infinite at it’s center, how can black holes even move? When matter moves through spacetime, it bends the spacetime around it, but if black holes are just regions of spacetime, how can a region in spacetime bend other regions of spacetime? And another question arises. If black holes are just regions in spacetime, how can it bend the spacetime around it, so it can remain a black hole, if there is no matter to continuously bend it?
