Tom Siegfried: The Number of Heavens

How many worlds are in our universe? How big is the universe? How does the universe “work”? These are questions that have been pondered since the time of Ancient Greece. Today cosmologists are considering whether there are “multi-universes”, but many of the questions they are wrestling with originally were posed in ancient times. In this episode of Inquiry, we talk with former Editor-in-Chief of Science News and award-winning science writer TOM SIEGFRIED. We will be discussing his new book: THE NUMBER OF THE HEAVENS: A HISTORY OF THE MULTIVERSE AND THE QUEST TO UNDERSTAND THE COSMOS.
