In what many call a “golden age of cosmology”, astronomers can now observe the universe with unprecedented precision, resulting in spectacular progress in the search for the origin of the universe. Yet, for all the impressive progress, fundamental questions remain. What is the mysterious “dark energy” driving space to rapidly expand? What existed before the big bang? Is there an origin of time? Do we live in a multiverse?
Our audience joined Science Friday’s Ira Flatow in conversation with leading cosmologists Lawrence Krauss, Paul Steinhardt, and Lyman Page, and historian of science Helge Kragh as they discussed and debated new advances that are shaping our understanding of the cosmic order and our place within it.
