One of the world’s major scientists explains why—and how—the look for clever existence past Earth may be expanded.
Fifty years in the past, a tender astronomer named Frank Drake first pointed a radio telescope at within reach stars within the wish of identifying up a sign from an alien civilization. hence begun one of many boldest clinical initiatives in historical past, the hunt for Extraterrestrial Intelligence (SETI). After a half-century of scanning the skies, even if, astronomers have little to document yet an eerie silence—eerie simply because many scientists are confident that the universe is teeming with lifestyles. Physicist and astrobiologist Paul Davies has been heavily concerned with SETI for 3 many years and chairs the SETI Post-Detection Taskgroup, charged with identifying what to do if we’re all of sudden faced with facts of alien intelligence. He believes the hunt to date has fallen into an anthropocentric trap—assuming that an alien species will glance, imagine, and behave very similar to us. during this provocative publication Davies refocuses the hunt, demanding current principles of what shape an alien intelligence may perhaps take, the way it may perhaps try and speak with us, and the way we must always reply if it does.
