Laura Mersini-Houghton (''née'' Mersini) is an Albanian-American cosmologist and theoretical physicist, and professor at the University of North Carolina at Chapel Hill. She is a proponent of the multiverse hypothesis and the author of a theory for the origin of the universe that holds that our universe is one of many selected by quantum gravitational dynamics of matter and energy. She argues that anomalies in the current structure of the universe are best explained as the gravitational tug exerted by other universes.
