Part One: Neil deGrasse Tyson on the New Cosmos

This week on Moyers & Company, Bill begins a new half-hour format with nothing short of the universe itself. In a multi-part series with the popular astrophysicist Neil deGrasse Tyson, Bill explores a variety of topics, including the nature of an expanding, accelerating universe (and how it might end), the difference between “dark energy” and “dark matter,” the concept of God in cosmology and why science matters. “Science is an enterprise that should be cherished as an activity of the free human mind,” Tyson tells Bill. “Because it transforms who we are, how we live, and it gives us an understanding of our place in the universe.” Starting in March, Tyson will host a new, updated version of the hit PBS television series Cosmos, which made the late Carl Sagan a household name. This time the new series, Cosmos: A Spacetime Odyssey, comes courtesy of the National Geographic Channel and Fox TV.
