Nobel Prize Winner, James Peebles: The Accelerating Expanding Universe: Dark Energy, Dark Matter, & Einsteins Cosmological Constant

Tuesday, November 5, 2019

In Ratra's talk, he will discuss why cosmologists think dark energy and dark matter are by far the main components of the universe's current energy budget — even though dark energy and dark matter have not yet been directly detected. According to Ratra, the data currently available has helped cosmologists develop a standard measurable and predictive model of how the universe was created and how it developed into the complex structure seen today. Ratra will also discuss the basic physics and the history of ideas — many developed by Peebles — on which this model of cosmology is based.
