Carnegie Mellon University Holds 2004 Buhl Lecture The Dark Side of the Universe: Beyond Stars and the Starstuff We Are Made Of

EVENT: Carnegie Mellon University will present a free public lecture by Michael S. Turner, one of the pioneers of the interdisciplinary field that has brought together cosmologists and elementary particle physicists to study the earliest moments of creation. While the sky is filled with hundreds of billions of galaxies, all lit up by their stars, stars account for less than one percent of material in the universe. Scientists now appreciate that galaxies are held together by a newly discovered form of matter, dark matter, which accounts for one-third of the stuff in the universe. The other two-thirds of the universe exists in an even more mysterious form, dark energy, which is causing the expansion of the universe to speed up, rather than to slow down. Turner's current research deals with the mystery of why the expansion of the universe is speeding up and not slowing down. He will explain today's explorations into the nature of dark matter and dark energy that seek to provide a deeper understanding of our universe and its origin.

Turner is the Rauner Distinguished Professor and Chair of the Department of Astronomy and Astrophysics at the University of Chicago. He also is assistant director for the Directorate for Mathematical and Physical Sciences of the National Science Foundation. A recipient of many honors, Turner is a fellow of the American Physics Society, which honored him with the Julius Edgar Lilienfeld Prize. He also is a fellow of the American Academy of Arts and Sciences and a member of the National Academy of Sciences.

Sponsored by the Carnegie Mellon Department of Physics, this lecture is funded under the auspices of the Buhl Professorship in Theoretical Physics, which was established at Carnegie Mellon in 1961 by the Buhl Foundation in support of an outstanding theoretical scientist who would both impact theoretical research and help establish directions for experimental investigations. For more information, please contact 412-268-6681.

WHEN: 4:30 p.m. Tuesday, April 27

WHERE: Mellon Institute Auditorium, 4400 Fifth Avenue Reception following the lecture in the Mellon Institute Lobby
