The Quantum Mechanics of the Universe

Classical general relativity predicts that the universe had a singular origin. I show that the singularity can be removed by quantum mechanics, just as in the case of the classical model of the atom. I propose that the quantum state of the universe is defined by a path integral over compact positive definite metrics. I show that in a simple model this boundary condition leads to a wave function which can be regarded as a superposition of wave functions peaked around classical oscillating solutions with a long inflationary period.
