China Says It May Have Detected Signals From Alien Civilizations (bloomberg.com) 186

China said its giant Sky Eye telescope may have picked up signs of alien civilizations, according to a report by the state-backed Science and Technology Daily, which then appeared to have deleted the report and posts about the discovery. From a report: The narrow-band electromagnetic signals detected by Sky Eye -- the world's largest radio telescope -- differ from previous ones captured and the team is further investigating them, the report said, citing Zhang Tonjie, chief scientist of an extraterrestrial civilization search team co-founded by Beijing Normal University, the National Astronomical Observatory of the Chinese Academy of Sciences and the University of California, Berkeley. It isn't clear why the report was apparently removed from the website of the Science and Technology Daily, the official newspaper of China's science and technology ministry, though the news had already started trending on social network Weibo and was picked up by other media outlets, including state-run ones.
UPDATE (6/18/2022):A co-author on the research project which first spotted the signals has now said the signals came from human radio interference, "and not from extraterrestrial."

    Sure hope the higher ups in China have read The Three Body Problem before they go sending response signals!

      Talking to alien civilizations less than, say, five light years away from us could be dangerous. While TFA is not clear on the point, it is likely the electromagnetic signals they have detected (in the unlikely event that they are really from an alien civilization) come from an exoplanet hundreds of light years away. Assuming the civilization still exists when they receive our response, I do not think they will have the technology to immediately blast us out of existence. If they have the desire to destroy us, it might be a concern for cockroaches, but I doubt the human race will still exist millennia from now.

        The general rule of Cosmology is: It's never aliens, until it is.

        So for now, it's a peculiar electromagnetic signal, nothing else. I am betting a pound of noodles, that it is not an alien civilization talking.

          Wonder if they have ruled out the microwave in the break room.

      • We have the technology to immediately blast ourselves out of existence. What makes you think that an alien civilization capable of interstellar flight would not?
        • because of the speed of light (c)... realistically any interstellar travel of matter happens at velocities small compared to than c, not just "less than c".

          And yes, that's part of sciece we know for sure. Just like the laws of thermodynamics, there is no way around it. We do not understand every subtle detail of particle physics, but we do know as much as this.

          • by HiThere ( 15173 )

            Actually there are ways around that. The only problem is they all require unobtainium of one sort or another. (E.g. large amounts of stuff with negative mass.)

            But unless they have something REALLY special, any solid object sent at even nearly c would dissolve from collisions with dust on the way here. I suppose the Alcubierre drive (a warp drive) might evade that, but I'm not sure.

            The way to bet is that FTL doesn't work in this universe. But it's unwise to be certain of that.

            • by dryeo ( 100693 )

              Even the Alcubierre drive is predicted to have a maximum speed of 10x light speed, so a year round trip to visit the nearest star, perhaps possible but in all likelihood, it is going to much further to the closest habitable planet

            • For now, we don't even understand why c is the speed limit in the universe.

        "Talking to alien civilizations less than, say, five light years away from us could be dangerous."

        I doubt that, the amount of energy it would take to reach light speed on any interstellar craft is huge. Then, you reach the problem that your craft disintegrates into pure energy. There is also the ramp up time and the ramp down time, assuming you've solved the energy problem. Having your aliens squished flat at either end might hamper their ability to conduct operations on Earth. They could send machines, but

        • by HiThere ( 15173 )

          If they're close enough, you don't need FTL. If you could get something up to 1% the speed of light, something 5 light years away could get here in about 500 years. And when it gets here it wouldn't need to slow down, just do orbital corrections to impact on the target.

          So it seems possible. Not very plausible, but possible. A 10,000 Kg impactor at 1% the speed of light = 9*10^21 newtons of energy. That's a lot more than the dinosaur killer.

          • 9*10^21 newtons of energy

            Umm...the newton is NOT a unit of energy. It's a unit of force. You were probably looking for joules.

            • by HiThere ( 15173 )

              Actually, I just picked mv^2 and then looked for the unit that fit. I probably should have divided by 2, but at that size it hardly matters.

        • I agree with you that sending spacecraft at anywhere close to the speed of light is probably not going to be feasible. However, I could well imagine a highly advanced civilization situated five light years away being able to inject something very into our solar system nasty within a century or so. Those are the kind of timescales that we theoretically would need to worry about. In practice, unless they already had assets in our immediate neighbourhood, it is hard to believe they would regard us as a high pr

        You know, just the knowledge that they exist might trigger a collapse, but if we communicated and *learned things* from them, well that would definitely destroy civilization. Maybe by replacing it with a better one
      • Talking to alien civilizations less than, say, five light years away from us could be dangerous.

        Liu Cixin's Three Body Problem series makes a good argument for what he calls the theory of "Cosmic Sociology", and what Cosmic Sociology says is (paraphrasing) "Don't talk to alien civilizations. Ever. Hide, and hide well, if you want to survive." He describes the universe as a dark forest, full of things that will eat you. Distance doesn't matter, because the other civilization might not be limited by distance, and even if it is, it may be willing to come kill you anyway.

      Yep, for some reason aliens are almost always humanoid and speak English. And even though they have no genes or ancestry in common with us, and may have copper blood, they cross-breed with us easier than monkeys can, too! Next up, new star trek movie; "Vulcan needs women!"

      • by AmiMoJo ( 196126 )

        In Star Trek canon all the humanoid species have a common ancestor race that seeded the galaxy with their own DNA. It's also been shown that for different species to breed requires some medical intervention using largely unexplained technology to make them compatible.

        • by HiThere ( 15173 )

          They probably use CAS-10.

        • The technical explanation is that all the actors were humanoid.

          It's a human problem, especially a city based human problem, the need to anthropomorphize everything. Ie, cartoons make it clear that a cow is female by adding feminine glasses (despite there being no male cows). Video games are confused; lizard women with boobs, dwarven women without beards, nonsense like that. If you want to imagine an alien species that isn't humanoid, just look on earth - lizards, scorpions, armadillos, etc.

      Yes, China has manufactured stories. So has almost everyone else. Manufactured stories have a purpose. The question here is: Which purpose would this one have?
      • My guess is the same purpose the others usually have...to draw attention away from something else. Perhaps like delays in lifting the lockdowns. Maybe more bank failures? Or any of the other PR bugaboos that manage to escape the Great Firewall.

        Well, if it's a manufactured story, it's probably directed at an internal target audience, and we're just accidental bystanders.

        OTOH, I think it much more likely that someone was overeager in interpreting data to fit their own hobby-horse. "China" isn't a monolithic entity any more than any other country is.

    The fact that the story does not mention where in the sky these signals were being received from gives absolutely nobody else the ability to corroborate their findings.

    Like others here, I call this article BS.

    • by jd ( 1658 )

      They wouldn't be able to, anyway. Nobody else has a radio telescope that large, or anything remotely close to being that large. And that won't change until the whole of SKA is online.

    • They wouldn't give out the location anyway. Any radio transmissions might have a technological edge, e.g. basic physics for an advanced civilisation, e.g. like normal and dark matter equations, which would give China an advantage. Maths is a fundamentally shared language so realistically it would be the first language any advanced species would begin to communicate with.
