    > They have been pointing China’s Five-hundred-meter Aperture Spherical Telescope, a radio telescope referred to as FAST, at these targets since July, hoping to see the signals again.

    This is how you get Trisolarians knocking on your door!

      This is what I thought also.

      Maybe they didn’t find any signals, but just said, “To heck with it. We’ll just say we found 100 signals, and let them come to us!”

      Only if you hit the transmit button.

        And that's why they won't find anything, IMHO. Anyone who spends five minutes thinking about the consequences of deliberately transmitting interstellar beacon signals will conclude that the only safe, sane thing to do is STFU.

        At the same time, no advanced civilizations will be using coherent RF communications that stand out from the noise floor, because it makes little sense to keep doing that once your civilization understands information theory.

        Still, SETI was an undeniably cool thing to try, and I'm glad they did. Lots of other cooperative-computing tasks grew out of the same idea as the article mentions.

            This reads like a Douglas Adams quote

    >“There’s no way that you can do a full investigation of every possible signal that you detect, because doing that still requires a person and eyeballs,” he said. “We have to do a better job of measuring what we’re excluding. Are we throwing out the baby with the bath water? I don’t think we know for most SETI searches, and that is really a lesson for SETI searches everywhere.”

    Is this not the perfect job for AI today? Just sit there and digest signals for 30 years and report back the top 1000? I'm quite sure it could even work on the algorithms as a side-quest.

      If nothing else, AI will probably be needed to filter out RF artifacts and spurious emissions from all the Internet satellite constellations that are either already online or ramping up in the future.

      This sort of effort really ought to be conducted with antennas on the far side of the Moon, IMO. But good luck finding the budget for that these days.

    I used to run this on my computer in the early 2000s. I wish we had a similar project nowadays.

    This assumes that ETs are deliberately transmitting high power signals towards us (or into space in general), although I'm not sure that is a reasonable assumption. I think it would generally be unwise to loudly announce a civilization's presence.

    According to chatgpt, our current earth-based radio telescopes would only be able to detect signals equivalent to radio leakage from earth at a distance of 1 light year.

      But what did you think?
