Dr. Bharat Ratra will be speaking on the following:
The Accelerating Expanding Universe: Dark Matter, Dark Energy, and Einstein's Cosmological Constant
Dark energy is the leading candidate for the mechanism that is responsible for causing the cosmological expansion to accelerate. I 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. I 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. I will also discuss the basic physics, and the history of ideas, on which this model is based.
These meetings are always open to the general public, free of charge. The meetings usually include speakers or presentations covering a wide range of topics relevant to astronomy.
Guests are always welcome to join us for the General Meetings and/or observing out at Farpoint.
