Dark Matter, Dark Energy, and the Accelerating Universe

Speaker: Dr. Bharat Ratra, KSU Physics Department

Date: Tuesday, January 24

Time: 7:00pm

Location: Radina’s Coffeehouse and Roastery, 616 N.Manhattan Ave

Description: Dark energy is the leading candidate for the mechanism that is responsible for causing the cosmological expansion to accelerate. (The observational discovery of the accelerating cosmological expansion was recently honored by the award of a Nobel Prize.) Dr. Bharat Ratra will describe the data which persuade cosmologists that (as yet undetected) dark energy and dark matter are by far the main components of the universe.
