Nor that there should be just one family of interconnected fields. We’ve got, what, two dozen or so? Some affect each other, some don’t. You can create a graph from that, and you get one that’s dense in places but have some nearly disconnected regions. Why not a graph with actual disjoint subgraphs? We’d only be able to tell through gravity.
