Andrew Hamilton, who will present the popular program "Black Holes and Relativity," at Fiske Planetarium, says the show was created partly by accident. The program is the second in a series of live public astronomy shows to be held at Fiske Planetarium at the University of ÃÛÌÇÖ±²¥ this semester. "Black Holes" is set for Tuesday, Feb. 16, and Friday, Feb. 19, at 7:30 p.m. It will last about an hour and a half.
