Summary: Fifty years ago, Frank Drake pointed a radio telescope at nearby stars in the hope of picking up a signal from an alien civilization. Thus began one of the boldest scientific projects in history, the Search for Extraterrestrial Intelligence (SETI). But astronomers have little to report except an eerie silence-eerie because many scientists are convinced that the universe is teeming with life. Could it be, wonders physicist and astrobiologist Paul Davies, that we've been looking in the ...show more wrong place, at the wrong time, in the wrong way? Closely involved with SETI for three decades, Davies now chairs the SETI Post-Detection Taskgroup, charged with deciding what to do if we're confronted with evidence of alien intelligence. He believes the search so far has fallen into an anthropocentric trap-assuming an alien species will look, think, and behave like us. In this mind-expanding and provocative book, he refocuses the search, challenging existing ideas of what form an alien intelligence might take, how it might try to communicate with us, and how we should respond if it does.
