Dark Matter, Dark Energy and the Accelerating Universe
Speaker: Dr. Bharat Ratra, Physics Professor at Kansas State University
Date: Monday, April 2
Time: 7:30 p.m.
Location: The Donut Whole, 1720 E. Douglas, Wichita, KS
Dr. Ratra’s research area is Cosmology and Astroparticle Physics. He develops models for the large-scale matter and radiation distributions in the universe and tests these models by comparing their predictions to observational data, including the anisotropy in the cosmic microwave background radiation, and the mass correlation function.
Experiments and observations over the last decade have provided strong support for a “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.
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.
