The base question, as I understood it, was if regions of curvature caused by mass cause regions of opposite curvature between them (rather than no curvature).
Mass effectively creates positive curvature in a region, so the question is if that "tugs" and create regions of negative curvature to keep the "total" curvature 0, in some sense. (There's actually several models here, depending on how you want to distribute the negative curvature.)
This isn't totally absurd on the face of it, for any reason I can think of, and brings up an interesting curvature conservation law.
The next question is if this model (curvature conservation) explains things we see, is contradicted by facts, etc. In parallel (though usually after) mechanisms by which the tugging would happen are proposed.
