Special open talk

Special open talk

On Nov. 24 at 6 p.m., there will be a special open lecture on "The Accelerating Universe: Dark Matter, Dark Energy and Einstein's Cosmological Constant" by Bharat Ratra, professor of physics at Kansas State University.

Dark energy is the leading candidate for the mechanism that is responsible for causing the cosmological expansion to accelerate. Bharat Ratra will describe the astronomical 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. He will review how these observations have led to the development of a quantitative "standard" model of cosmology that describes the evolution of the universe from an early epoch of inflation to the complex hierarchy of structure seen today. In this non-technical talk, he will also discuss the basic physics, and the history of ideas, on which this model is based. 

PLACE: Littrow Hörsaal, Sternwarte

TIME: 18:00
