However, this is a "weak field" (nearly Lorentz metric) approximation and one thing for sure about so-called "black holes" is that they are not weak fields! One cannot legitimately treat them as embedded in a flat background space-time when discussing questions such as this in regions very "near" the black hole. My feeling is that one could "define" terms such that gravitational effects propagated locally at the speed of light, even "inside" a black hole. I don't know what good this would do, though. P.S. I'll believe in black holes the day that I see a solution to the real field equations that looks like one, not just to the old 1916 equations.
