Professor Bharat Ratra's public lecture " THE ACCELERATING EXPANDING UNIVERSE: DARK MATTER, DARK ENERGY, AND EINSTEIN'S COSMOLOGICAL CONSTANT
Events
On December 10, at 4:00 p.m., a public lecture by Professor Bharat Ratra of Kansas State University will be held in Auditorium G106 of Ilia State University; the lecture topic: "The Accelerating Expanding Universe: Dark Matter, Dark Energy, and Einstein's Cosmological Constant".
A brief overview of the topic
Dark energy is the leading candidate for the mechanism that is responsible for causing 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.
About Author
Bharat Ratra, a distinguished professor of physics, works in the areas of cosmology and astroparticle physics. He researches the structure and evolution of the universe. Two of his current principal interests are developing models for large-scale matter and radiation distributions in the universe and testing these models by comparing predictions to observational data.
