Are we alone in the universe or is it possible that alien life is right under our noses or even in our noses? Cosmologist Paul Davies is the director of the Beyond Center in Arizona and chairs the Search for Extraterrestrial Intelligence Post Detection Task Group, which means that he is one of twelve people in the world who will be the first to know if we make contact with aliens. He is also the author of The Eerie Silence.
