Sometimes the biggest moments in scientific history happen in the most unlikely places. There’s no better example than the story of Nobel Prize-winning scientist Subrahmanyan Chandrasekhar, a longtime University of Chicago scholar whose pioneering research paved the way to the discovery of black holes. Chandrasekhar’s story is the first in a special series called “The Day Tomorrow Began,” in which we will examine the historical origins of some of the most breakthrough ideas to happen at the University of Chicago that have reshaped our world—and how scholars today are transforming our future. Joining us in exploring the history of black hole research are University of Chicago cosmologist Daniel Holz, Nobel Prize-winning black hole scholar Andrea Ghez and renowned UChicago theoretical physicist Robert Wald.
