Stephen M. Barr is an American author and professor in the Department of Physics and Astronomy at the University of Delaware, and a member of its Bartol Research Institute. He is also President of the Society of Catholic Scientists. Barr does research in theoretical particle physics and cosmology. In 2011, he was elected Fellow of…
James B. Hartle was Research Professor and Professor of Physics Emeritus at the University of California, Santa Barbara. His scientific work was concerned with the application of Einstein’s relativistic theory of gravitation—general relativity—to realistic astrophysical situations, especially cosmology. He has contributed usefully to the understanding of gravitational waves, relativistic stars, black holes, and the theory…
Dr. Giddings is a researcher and professor at the University of California at Santa Barbara, specializing in theoretical physics. His current research includes investigating the quantum nature of spacetime, and what happens to information that is sent into black holes. He studied mathematics and physics at the University of Utah, and then went to Princeton…
Laura Mersini-Houghton 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, which holds that our universe is one of many. She argues that anomalies in the current structure of the universe are best explained as the gravitational tug…
Fred Adams is a professor of physics at the University of Michigan. His work is in the general area of theoretical astrophysics with a focus on the study of star formation and cosmology. Adams is internationally recognized for his work on the radiative signature of the star formation process, the dynamics of circumstellar disks, and the theory…
