Abstract
We elaborate the recently introduced asymptotically exact semiclassica l quantum gravity derived from the Wheeler-DeWitt equation by finding a particular. coherent-state representation of a quantum scalar field in which the back-reaction of the scalar field Hamiltonian exactly giv es rise to the classical one. We show that classical spacetime emerges naturally from the coherent-state representation of the semiclassical quantum gravity.
