The Chern-Simons-Kodama state of quantum gravity, a generalization of the Hartle-Hawking and Vilenkin states, has a striking structural similarity to the topological field theory of the quantum Hall effect. As a result, we study the gravitational…</p><p><a href="https://hackerpaper.kaipfister.de/p/2506.14886/">Paper and discussion history</a>. A mention is not an endorsement.</p>gr-qc
