SETI's 'Strong Signal' Came From Earth (arstechnica.com) 146

Posted by BeauHD from the false-alarm dept.
Yesterday, it was reported that Russia has detected a strong signal around 11 GHz coming from HD164595, a star nearly identical in mass to the Sun and located about 95 light years away from Earth. Well, long story short the signal came Earth. Ars Technica reports: "First, astronomers with the search for extraterrestrial intelligence downplayed the possibility of an alien civilization. 'There are many other plausible explanations for this claimed transmission, including terrestrial interference,' Seth Shostak, a senior astronomer with SETI, wrote. Now the Special Astrophysical Observatory of the Russian Academy of Sciences has concurred, releasing a statement on the detection of a radio signal at the RATAN-600 radio astronomy observatory in southern Russia. 'Subsequent processing and analysis of the signal revealed its most probable terrestrial origin,' the Russian scientists said."

      Besides - this just means there might be some sort of giant super mirror out there. Cool either because, well, aliens right? But I would imagine also that the astrophysics folks would get some serious geek out moments from it...

    That may be shortening the story a little too much. Or did the Earth get here via a signal from another star 95 light years away? I'd say that's some pretty big news.

    • Since the star is 95 LY away, that would imply that if the "mirror" is at the star, then the round-trip time would be 190 years. So, a very powerful terrestrial signal at 11 GHz in 1826.

      I'm not even sure that sparks generate anything like that high a frequency. They were just getting as far as solenoids and galvanometers, as I recall. Maybe just getting a handle on induction.

      I'll admit a 180 year round trip makes for slow conversations, but if we were to establish communication with an intelligent race elsewhere in the universe, there's no telling what we might learn from them. Physical travel between stars might never be practical, but an exchange of science, art, culture, and philosophy could be a practical reality. And any civilization we can detect across interstellar distances is almost certainly far more technologically advanced than we are, so there's no telling what we might learn.

      Of course any sort of two-way communication begun at this point would be irrelevant to anyone currently alive, aside from whatever sociological fallout there might be to discovering with certainty that we're not alone (I'm sure a few religions would squirm for a while, and plenty of new cults would pop up), but there's also the possibility that a signal is the first of many to be detected, with further, more information-rich signals already in transit. Possibly at a much lower power that would be harder to detect. Like a loud, fiendishly expensive "Hey, Listen" chirp periodically introduced into an otherwise more economical data transmission.

      • there's no telling what we might learn from them.

        And what could that possibly be?

        There are intelligent aliens. Okay, that would be a pretty groundbreaking discovery all by itself.

        We'll probably not learn much in the ways of science or technology from them, or at least no much that we couldn't discover ourselves within a reasonable (few hundred years) timespan.

        That basically leaves philosophy and possibly religion as topics. And poetry.

          Considering the chaotic fits and starts with which life and civilization emerged on this planet, and the potential timing differences that could accumulate over a few billion years make it more likely that their civilization would be thousands or even millions of years ahead of ours than only centuries. And even if by some miracle they were of a comparable tec

            I'm just working under the assumption that any aliens we actually get to talk to will have roughly our level of science and technology. Any civilization significantly more advanced will probably not bother talking to a bunch of unwashed barbarians.

We thought in the 1800s that we knew almost all there was to know about physics, with only a few odd anomalies unexplained - anomalies which eventually led to QM and Relativity and fundamentally changed how we saw the universe, and greatly expanded how we could manipulate it. Today we know with certainty that our current theories are at least incomplete, possibly fundamentally flawed, and there's no telling how many more world-changing revisions are yet to come.

                Any alien civilization with significantly more advanced knowledge of physics will probably not bother talking to us, unless they're really bored or see it as the duty to enlighten less advanced civilizations.

                And if their knowledge of civilization is only slightly more advanced than ours, we can probably catch up to their level in the time (>100 years) it takes for our message to get there and their response to get back here.

          and don't give me shit about "string theory", those wankers have been going at it for decades with NOTHING provable to show for their nonsense, unlike GR and QM which at least are useful in their realms and predict experiments we can do

          • The problem is that we can't break GR and QM adequately with current experiments and observations. Until we can break a scientific theory, we can't replace it.

                Einstein himself showed that GR explained at least one phenomenon (perihelion precession) that Newtonian mechanics didn't.

                All the other observations just served to confirm GR over and over.

      • I'm most interested in their art, culture, philosophy, and religion. We have millennia of practice and study of human thought in these fields, and it would be fascinating to have something to compare it to.

        To give one example: some people have spiritual experiences. These are either real or based on some oddities of brain evolution, and a completely different evolution situation would be unlikely to come up with the same oddities.

      10.7 to 12.7 GHz is the Ku band satellite downlink band in Europe. If it was 11 GHz I would think it would be hard not to receive interference in a side lobe. I can't find the exact frequency online--only that the front end has a 1 GHz bandwidth which also seems odd. Once someone other than the media looked into this it became a non-event anyway.
