So what have we learned about this quantum gravity so far? Well, we have a statistical nature to gravity now - the wave function has given geometry a probabilistic property. When you see something like this \(<\psi|A|\psi>\) in the Hilbert space, it is describing the expectation value. It seems very natural to continue from here, in the usual way, by adopting either a Heisenberg or Schrodinger picture, which would chose essentially which feature of this equation, the operator or the vector is time dependent. This has a remarkable consequence if we took the operators, which in this case is a set of three commutation relationships describing gravity - because essentially gravity would become time-dependent which is a much different interpretation to the usual one which follows the Wheeler de Witt universe.
