Pregeometric origin of the big bang.
Abstract
The temperaturedependent effective action for gravity is calculated in pregeometry. It indicates that the effective potential for the spacetime metric has the minimum at the origin for extremely high temperature. The origin of the big bang can be taken as a local and spontaneous phase transition of the spacetime from the pregeometric phase to the geometric one.
