...........The gravity doesn't have to get out of the black hole. General relativity is a local theory, which means that the field at a certain point in spacetime is determined entirely by things going on at places that can communicate with it at speeds less than or equal to c. If a star collapses into a black hole, the gravitational field outside the black hole may be calculated entirely from the properties of the star and its external gravitational field before it becomes a black hole......... The above quote (not mine) does express the factual theoretical point. As per my understanding what it implies is that the Gravity of the collapsing star before it becomes a BH (collapses to singularity) manifests itself around the spacetime (outside EH), because once it becomes a BH the communication with outside world (>EH) is not known to us. This explanation would have been fantastic if we treat a BH as static object, no translation motion with respect to....?, I really do not know with respect to what, say infinity. But a BH has a translation motion, in the case when BH itself moves, it cannot synchronize with the spacetime outside where the field resides. Synchronization is required for the simple reason that multiple properties are assigned to the field around. Is it not a paradox, one way we are saying that there is a theoretical disjoint on either side of EH, and on the other way we are accepting the synchronized translation movement of the field outside and whatever inside.. PS : 1. Fossil Field, Gravity Gravitates, Non Linearity of EFEs, Frozen Star...none appears to me to resolve this.
