The Hamiltonian admits self-adjoint extensions that give unitary evolution in the Hilbert space associated with the Schr\\\"odinger equation. The semiclassical estimate to the no-boundary wave function of Hartle and Hawking is found. If this estimate is accurate, there is a continuous flux of probability into the configuration space from vanishing three-volume, and the no-boundary wave function evolves","authors_text":"Alan Daughton, Jorma Louko, Rafael D.
