Description
We revisit the dynamics of black holes using the canonical approach to quantum gravity. By introducing time slices that cover both the inside and the outside of the horizon, we obtain the Wheeler-DeWitt equation. It is not possible to solve it directly, but it is possible to see potential dynamics and boundary conditions. From this, we can conclude that we cannot provide a coherent state that covers both the outside and the inside of the horizon. We will discuss the possible physical meaning of this and apply it to the information loss paradox.
