Can the universe be charged\?
Abstract
We point out a possibility of temporal charge nonconservation in cosmological models based on moredimensional theories à la KaluzaKlein. A net excess charge may then have been created before the extra dimensional space was compactified. Cosmological implications of the excess charge are discussed.
