What is the evidence for "dark energy" and "dark matter," and what are the implications? NOVA explains how teams trying to measure the rate at which gravity is slowing the expansion of the universe (by analyzing the red shift of supernovas) discovered that, contrary to all expectations, the expansion of the universe is accelerating. Why? What does this mean for the fate of the universe? DVD extras include lesson plans. Grades 7 and up. Closed captioned. Color. 56 minutes. WGBH. ©2000.
