The Course of Time

Where did we come from, and where are we going? Whether it's the Garden of Eden and Armageddon, or the Big Bang and the Big Freeze, we can't help but ponder our place in the universe. In this hour of To the Best of Our Knowledge, we consider the universal course of time, from the beginning to the end… and back again. A cosmologist discusses creation, and ponders when the universe became self aware. A documentary film producer examines African creation myths and their relationship to science. Novelist Jim Crace talks about his apocalyptic vision in The Pesthouse. And Ron Mallet talks about his efforts to disrupt the natural course of time through the very real possibility of time travel.
