Are we asking aliens to attack us?
After decades of searching, scientists have found no trace of extraterrestrial intelligence. Now, some of them hope to make contact by broadcasting messages to the stars. Are we prepared for an answer?
From Seed Magazine...
This is one reason why most SETI pioneers advocated a "first, just listen" approach. But there is another: What if there is something dangerous out there that could be alerted by our broadcasts? This ground has been explored in numerous scientific papers and, of course, in countless works of science fiction. Few people alive today embody the convergence of hard science and fictional speculation better than David Brin, an author of both peer-reviewed astronomy papers and award-winning science fiction novels. In an influential 1983 paper titled "The Great Silence," Brin provided a kind of taxonomy of explanations for the lack of an obvious alien presence. In addition to the usual answers positing that humanity is alone, or so dull that aliens have no interest in us, Brin included a more disturbing possibility: Nobody is on the air because something seeks and destroys everyone who broadcasts. Like Billingham and Michaud, he feels the PSG is dominated by a small number of people who don't want to acknowledge Active SETI's potential dangers.
