Wheeler's Holy Grail

This book presents the derivation of Dewitt-Wheeler equation in which time-independent equation describes the quantization of the gravitational field in 3-geomtries configuration. This equation may refer as Schrodinger-Einstein equation. This approach of the quantization of the gravity started by Dewitt according to Everett interpretation of quantum mechanics that yields the multiverse idea, and so, the WDW equation introduced a function called lapse function in which each different lapse function according to Dewitt yields a different sequence of 3-geometries that indicates to multiverse. On the other hand, according to Bohm¿s interpretation of quantum potential, the universe is considered as a quantum mechanical system with zero size, and so, the universe may tunnel with a well-defined, nonzero probability which express the creation from non-thing. This idea of the creation from non-thing is supported by Hawking in his articulation in 1988, that, in fact, there was no singularity at the beginning of the universe "it can disappear once quantum effects are taken into account". Penrose agreed.
