We are still in the dark with dark energy. The intricacies of it are unknown, but Bharat Ratra, a
Distinguished Professor of physics at Kansas State University, has dedicated his research to

Universe. In fact, the discovery that cosmological expansion is accelerating is one of the most
significant scientific discoveries of the last quarter century.
Ratra’s research tells us that the universe is expanding, and so are the opportunities
more with the Honors College. Join us and Ratra for an illuminating chat about dark matter,
