Is SETI Worth It?

Posted by CowboyNeal on from the lights-are-on-but-no-one's-home dept.

njdube sent in this Space.com story about the money behind SETI that opens, "It's a risky long shot that burns up money and might never, ever pay off. So is searching for intelligent creatures on unseen worlds worth the candle? After all, aren't there better ways to use our monies and technical talents than trying to find something that's only posited to exist: sentient beings in the dark depths of space?"

    It's written by Seth Shostak, who has been one of the people involved with SETI for a number of years and is in favor of continuing the research. Last time I checked SETI is now a non-profit that uses donations to fund their research. If that's what people want to donate their money to and think it is worth while, then let it continue.

    If you RTFA the Government donation "was" prior to 1993 was approx 3 cents for every person in the US. After 1993 Government spending on SETI is "zero", so all monies donated to SETI is by private individuals. There are many ways of contributing, one would be to donate money, the other donate a portion of your PC clock cycles and therefore electricity which someone will have to pay for eventually. In some way this is like "Folding at Home" except there are more perceived tangible results to be had but you still have to make a decision to provide the service, however like SETI no one forces you. Basically it is your choice your money and the Government is not involved.

    SETI is looking for a signal from an advanced civilization that is deliberately using archaic methods to transmit. What I mean is that they're looking for a beacon signal that's designed to be easy to interpret, and that's transmitted at an extremely high power level.

    On a practical level, that's the best they can do. Using the best receivers that we currently have, it'd just barely be possible to detect a megawatt-level signal from a few light years away, if it was aimed right at us. Detecting the equivalent of leakage from a TV transmission is a complete fantasy. Unless there's someone out there that's really desperate to be heard, we'll never find them.

    And of course, we're not about to start a program of sending similar signals to all the nearest stars - that'd take real money. If we detect a signal, then we might respond back.

    Unfortunately, the same argument holds in the other direction, too. Any alien civilizations out there would be foolish to waste the resources to send a signal we could detect, before they were sure we were there to hear it. When I think about SETI, I sometimes imagine thousands of intelligent species out there, all monitoring their antenna arrays, waiting for a signal that none of them have the funding to send...
