Maybe I understand it poorly but this field basically acts as a bubble encapsulating a piece of our three dimensional universe, right? But if gravity is a result of inter dimensional interaction then gravity will not work within that bubble. No science or math I can put behind it but I have long thought gravity is a consequence of 3rd dimensional mass interacting with higher dimensional physics, so that removing that interaction would nullify the effect. The theory of this interaction does make things like black holes seem more feasible and also seems to help explain the dark matter effect in my mind. Oh well, the pain of someone who loves theory but sucks at math.
