The energy equation of the Friedmann universe, when matter dominates over radiation, is examined. It is shown that the mass-energy of the universe relative to an observer in the nonmetric space outside the universe is equal to zero; i.e., the universe originated as a vacuum fluctuation. The origin of the gravitational force that retards expansion is considered using the properties of the relativistic gravitational potential; the viewpoint of an observer inside the universe is employed. It is shown that the boundary of the closed universe is a nonlocalizable potential barrier. Finally, an attempt is made to resolve the apparent discrepancy between Mach's principle and the general theory of relativity.
