Katherine Freese, Professor of Physics, University of Texas at Austin - Dark Matter in the Universe

Dark Matter in the Universe

The ordinary atoms that make up the known universe, from our bodies and the air we breathe to the planets and stars, constitute only 5% of all matter and energy in the cosmos. The remaining 95% is made up of a recipe of 25% dark matter and 70% dark energy, both nonluminous components whose nature remains a mystery. Freese will recount the hunt for dark matter, from the discoveries of visionary scientists like Knut Lundmark and Fritz Zwicky, who argued for the existence of dark matter in the 1930’s, to the deluge of data today from underground laboratories, satellites in space, and the Large Hadron Collider.
In this talk Freese will provide an overview of this cosmic cocktail, including the evidence for the existence of dark matter in galaxies. Many cosmologists believe we may be on the verge of solving this mystery, which will be an epochal discovery in humankind's quest to understand the universe.
She is author of a book The Cosmic Cocktail: Three Parts Dark Matter, published by Princeton University Press. Dr. Freese’s work has been described in The New York Times, BBC, Scientific American, New Scientist, National Public Radio, Boston Globe, Dallas Morning News, and other media. Her public appearances include Through the Wormhole with Morgan Freeman, a BBC Horizon Dark Matter documentary, a New York Academy of Sciences Panel, TV Ontario, and the Isaac Asimov Debate at the American Museum of Natural History in New York.
