Dark matter expert speak Feb. 26
Sunday, January 25, 2009
ST. CLOUD, Minn. – Dan Hooper will lead you out of the dark about dark matter.
Hooper, an astrophysicist and 1999 graduate of St. Cloud State University, will discuss dark matter 7 p.m. Thursday, Feb. 26, in a free public presentation in Stewart Hall's Ritsche Auditorium.
He will discuss the unseen universe that physicists argue has more mass than the visible universe. He will explain how physicists infer the existence of dark matter by observing its gravitational effect on galaxies.
The talk is titled “In Search of Our Universe's Missing Mass and Energy.”
Hooper has written two amateur guides to the universe: “Dark Cosmos: In Search of Our Universe’s Missing Mass and Energy” (HarperCollins) and “Nature’s Blueprint: Supersymmetry and the Search for a Unified Theory of Matter and Force” (Collins). He also has published 100 articles in refereed journals.
Hooper earned his doctorate at the University of Wisconsin in Madison and completed a postdoctoral fellowship at Oxford University in England.
In 2008, Hooper received the St. Cloud State University College of Science and Engineering Leadership Alumni Award for his career accomplishments.
Hooper's talk is part of the Physics and Astronomy Seminar Series sponsored by the Department of Physics, Astronomy and Engineering Sciences. It was scheduled Oct. 16, but cancelled due to illness.
Questions may be directed to John Harlander, professor of physics, astronomy and engineering science, at 320-308-4974.
