I’m not sure whether it’s the standard view in physics, but Sean Carroll has suggested that we should think of locality in space as deriving from entanglement. (With space itself as basically an emergent phenomenon.) And I believe he considers this a driving principle in his quantum gravity work.
When we zoom out, does the graph take on the geometry of a smooth, flat space with a fixed number of dimensions? (Answer: yes, when we put in the right kind of state to start with.)
I don’t understand the article enough to decode what “the right kind of state” means, but this feels like circular explanation. The three-dimentional space can “emerge” from a graph, but only assuming it is the right kind of graph. Okay, so what caused the graph to be exactly the kind of graph that generates a three-dimensional space?
Well, possibly exactly the right kind of graph to be a mostly 3 dimensional space that curves in complicated ways based on the contents of that space as specified by General Releativity. The GR view of space is considerably less compact and simple than just R3 and making GR fall out of a graph like that with any kind of rigor would be impressive and maybe useful.
