Information on the gravitational interaction of a massive black hole with the surrounding stars in a galactic nucleus is reviewed, and the hypothesis that massive black holes are the primary energy sources in active galaxies and quasars is examined. Tidal disruption of stars, the flux from stars to a black hole, and the growth of a black hole are discussed, and mechanisms preventing the formation and growth of black holes in normal galactic nuclei are considered. It is suggested that the luminosity requirements of bright quasars and weak Seyferts can be accounted for by a model which assumes that massive black holes are their primary energy source, but the model is less successful in accounting for cosmic objects in the intermediate range. Difficulties associated with the model, including the observed periodic and quasi-periodic variability as well as the need for separate evolution of active galaxies and normal galaxies, are described.
