Ratra to Speak at Topeka Science Cafe July Meeting on Dark Matter & Dark Energy

Professor Bharat Ratra will speak at the Topeka Science Cafe July Meeting (July 16). He will be speaking on Dark Matter, Dark Energy, and the Accelerating Universe. Come to the Lazy Toad (5331 SW 22nd Place in Topeka) at 5:30 pm to order food and drinks; presentation starts at 6:00, followed by Q&A time. 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. 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 energy budget of the universe at the present time.
