By applying quantum rules to closed Friedmann universes, DeWitt found a way of avoiding singularities present in the classical theory. In the quantum theory presented in this paper singularities are not avoided but are smeared with quantum uncertainties. The smearing is accomplished by altering the topology of the configuration space of a Friedmann universe. Although this topological change does not affect the classical dynamics, it profoundly affects the Hilbert space of quantum states of both open and closed universes. In our quantum model there is tunneling through the singularities.
