In this Web version of Game Changers on The Longhorn Network, UT Austin astrophysics professor Karl Gebhardt addresses some big issues in his work. Big, as in galactic.
Most of his career has focused on understanding the role that black holes play in the formation of a galaxy. Now he is helping lead a new scientific revolution: the quest to understand dark energy, a mysterious force that makes up 70 percent of the matter and energy in the universe.
UT Game Changers brings The University of Texas at Austin’s intellectual talent beyond the classroom with a half-hour show to be broadcast on The Longhorn Network along with a Web-only version, above.
