Mark J. Solomon (born 1969) is an American non-fiction writer, philosopher and published neuropsychologist. In Solomon's first work, On Computer Simulated Universes (2013), he entertains just one central idea, that all of us exist within a computer simulated universe. In his second work, The Evolution of Simulated Universes (2014), the author contends that our Universe, not unlike our own human species, is the direct product of natural selection and evolutionary forces. He concludes that if our Universe is simulated, then the selection and evolution of simulated universes becomes inescapable. Solomon attended Washington University in St. Louis, T.T.U., Tulane University & Brown University. He resides with his wife in North Carolina.
