Einstein thought gravitational waves were too weak ever to be detected. But now, on the centennial of his prediction of them, scientists working on the project called LIGO (Laser Interferometer Gravitational-wave Observatory) believe we now have the sensitivity required to "hear" these tiny and elusive signals. Using giant "microphones" consisting of 4-km-long laser cavities in Washington and Louisiana, LIGO is listening intently to the Universe. Has anything gone bump in the night?
All talks are free and refreshments will be served. Visitor parking for the seminars (Central Campus) is across the street from Weiser Hall (formerly the Dennison Building) in the U-M Church Street parking structure. There is a $2.00 parking charge implemented by U-M Parking Services. For more information regarding the Saturday Morning Physics series click here or call 734.764.4437.
