Here's my conversation with quantum physicist Jim Al-Khalili about his book, "Aliens: The World's Leading Scientists on the Search for Extraterrestrial Life." Among the questions I asked him:
Can we say definitively that there’s no other life in our solar system other than on Earth?
What are the odds that life elsewhere has evolved faster or further than humans?
Would that life have to be carbon-based, like us, and need water?
Would we would recognize it as intelligent?
What will space travel look like in the future, and will humans or robots make the trip?
What are the misconceptions about alien life that have been perpetuated by movies, TV, and books?
