The SETI Project – Could It Possibly Bear Great Danger?

Who wouldn’t want to know whether or not there are other forms of intelligent life out there… Ever since the first attempts in the 60’s to make contact with alien lifeforms, SETI is still making great efforts. With all the messages that have been sent out, some scientists think we may putting ourselves in great danger:

Alexander Zaitsev, Chief Scientist at the Russian Academy of Sciences’ Institute of Radio Engineering and Electronics, has access to one of the most powerful radio transmitters on Earth. Though he officially uses it to conduct the Institute’s planetary radar studies, Zaitsev is also trying to contact other civilizations in nearby star systems. He believes extraterrestrial intelligence exists, and that we as a species have a moral obligation to announce our presence to our sentient neighbors in the Milky Way—to let them know they are not alone. If everyone in the galaxy only listens, he reasons, the search for extraterrestrial intelligence (SETI) is doomed to failure.

Zaitsev has already sent several powerful messages to nearby, sun-like stars—a practice called “Active SETI.” But some scientists feel that he’s not only acting out of turn, but also independently speaking for everyone on the entire planet. Moreover, they believe there are possible dangers we may unleash by announcing ourselves to the unknown darkness, and if anyone plans to transmit messages from Earth, they want the rest of the world to be involved.

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.

  1. In my early paper

    Sending and Searching for Interstellar Messages

    was illustrated that usual radar astronomy observations represent lot more “dangerous”…
