Is there more evidence for God or for aliens? Can true reality be described by science or will it always remain a mystery? Are there limits to our imagination? These are some of the questions I debate with Leonard Mlodinow. Not only has he co-authored books with Stephen Hawking, he’s also written for Star Trek, which make his perspectives among the most unique I’ve encountered. But we don’t always agree. And over the years that has turned us into close friends, as well as collaborators. As a man with many layers, our journey today is sure to expand your mind, as it has mine.
