Edward "Rocky" Kolb gives Buhl lecture on "Mysteries of the Dark Universe"
Renowned physicist Edward W. "Rocky" Kolb will deliver Carnegie Mellon University's annual Buhl Lecture, titled "Mysteries of the Dark Universe," at 4:30 p.m., Tuesday April 21 at the Mellon Institute Auditorium, 4400 Fifth Ave., Oakland. The lecture is free and open to the public, and will be followed by a reception in the Mellon Institute Lobby.
Ninety-five percent of the universe is missing. The mysterious missing pieces are made up of dark matter and dark energy. While scientists have yet to recreate dark matter or dark energy, the evidence for their existence comes from the gravitational pull exerted by dark matter and the accelerating expansion of the universe due to dark energy.
In his lecture, Kolb will discuss new astronomical facilities, particle accelerators and laboratory experiments cosmologists across the world are now building and using to better measure and understand dark matter and dark energy. Researchers at Carnegie Mellon are involved in some of these endeavors, like the Large Hadron Collider and Large Synoptic Survey Telescope.
Kolb is the department chair and Arthur Holly Compton Distinguished Service Professor of Astronomy and Astrophysics at the University of Chicago, and a member of the Enrico Fermi Institute and Kavli Institute for Cosmological Physics. In 1983, he was the founding head of the Theoretical Astrophysics Group and in 2004 the founding director of the Particle Astrophysics Center at Fermi National Accelerator Laboratory in Batavia, Ill. He is a fellow of the American Academy of Arts and Sciences and the American Physical Society.
The author of more than 200 scientific papers, Kolb's research focuses on the application of elementary particle physics to the very early universe. He is a co-author of the standard textbook on particle physics and cosmology, called "The Early Universe." His book for the general public, "Blind Watchers of the Sky," received the 1996 Emme Award from the American Aeronautical Society.
The Buhl Lecture is sponsored by Carnegie Mellon's Department of Physics. The 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.
