Astrobiology, looking for life in the universe
- Discusses some changes in scientific knowledge that have occurred since twenty years ago, when most scientists believed Earth was the only planet in our solar system where life could exist. Since then, major revolutions in our understanding of life on Earth have altered that notion completely, including the discovery of a very rapid origin of life, the ability of life to exist in environments previously thought too extreme, and genetic information on the biological nature of the earliest life. He also discusses the philosophical implications of searching for extraterrestrial life, what it would mean to find it, and what it would mean not to find it.
