Evolutionary Reformulation of the Quantum Gravity |
Abstract _ |
We present a critical analysis of the Canonical approach to quantum Gravity, which relies on the ambiguity of implementing a space-time slicing on the quantum level. We emphasize that such a splitting procedure is consistent only if a real matter fluid is involved in the dynamics, because it is endowed by a time-like versor. Since the non-test character of a quantum reference frame is fixed, then a dualism between a dust fluid and a physical time variable arises. The phenomenological issues of a Schr\"odinger quantum gravity are then discussed and the overlap to the Wheeler-DeWitt approach is established. |
