Geoff Marcy, Professor of Astronomy, UC Berkeley
Dan Werthimer, SETI Program Director, UC Berkeley

Science fiction often portrays our galaxy as teeming with advanced civilizations engaged in interstellar commerce and star wars. Back in our real universe, extraterrestrial life has proved elusive. The arguments for and against technologically advanced life in the galaxy have sharpened in recent years. Evidence abounds on Earth of the hardiness of life, even in extremely harsh environments. Other evidence suggests the Earth may be a rare type of planet, unusually suited to life as we know it. Which one is right? Renowned SETI scientist Werthimer will debate planet-hunter and skeptic Marcy.
