‘Dark Side of the Universe’ talk March 9 9:55 a.m., Feb. 28, 2005--Jordan A. Goodman, professor and chairperson of the physics department at the University of Maryland at College Park, will speak on “Neutrinos, Dark Matter and the Cosmological Constant--The Dark Side of the Universe” at 4 p.m., Wednesday, March 9, in 104 Gore Hall. Refreshments will be served at 3:30 p.m. in 225 Sharp Laboratory. In an abstract of his talk, Goodman wrote: “The composition and ultimate fate of the universe has long been the subject of speculation by cosmologists. A wealth of new data has transformed this once theoretical science into an observational one, and the results have surprised nearly everyone. “Stars are found to make up only a small fraction of the matter in the universe. Neutrinos contribute a comparable amount. Together they make up less than 1 percent of the energy density required to make the universe geometrically flat. Yet, recent data confirms what particle theorists have long insisted--that the universe is indeed flat. So what makes up the rest of the universe? “In this talk, I will review the recent results on neutrino mass, dark matter and the mysterious force which may be driving the universe apart--the cosmological constant.” The colloquium is sponsored by UD’s Department of Physics and Astronomy and the Bartol Research Institute.
