'Amazing' New Technology Set To Transform the Search For Alien Life (theguardian.com) 127

Robin McKie writes via The Guardian: Scientists with Breakthrough Listen, the world's largest scientific research program dedicated to finding alien civilizations, say a host of technological developments are about to transform the search for intelligent life in the cosmos. These innovations will be outlined at the group's annual conference, which is to be held in the UK for the first time, in Oxford, this week. Several hundred scientists, from astronomers to zoologists, are expected to attend. "There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI," said astronomer Steve Croft, a project scientist with Breakthrough Listen. "They are going to transform how we look for alien civilizations."

Among these new instruments are the Square Kilometer Array, made up of hundreds of radio telescopes now being built in South Africa and Australia, and the Vera Rubin Observatory that is being constructed in Chile. The former will become the world's most powerful radio astronomy facility while the latter, the world's largest camera, will be able to image the entire visible sky every three or four nights, and is expected to help discover millions of new galaxies and stars. Both facilities are set to start observations in the next few years and both will provide data for Breakthrough Listen. Using AI to analyze these vast streams of information for subtle patterns that would reveal evidence of intelligent life will give added power to the search for alien civilizations, added Croft.

"Until now, we have been restricted to looking for signals deliberately sent out by aliens to advertise their existence. The new techniques are going to be so sensitive that, for the first time, we will be able to detect unintentional transmissions as opposed to deliberate ones and will be able to spot alien airport radar, or powerful TV transmitters -- things like that." [...] Croft remains optimistic that we will soon succeed in making contact. "We know that the conditions for life are everywhere, we know that the ingredients for life are everywhere. I think it would be deeply weird if it turned out we were the only inhabited planet in the galaxy or in the universe. But you know, it's possible."

    Complex multicellular life took over 3 billion years to evolve on Earth and then Earth went through multiple mass extinction events, and that doesn't bode well the emergence of intelligent life everywhere. Couple that with the unique conditions that Earth has enjoyed that increased the rate of evolution and allowed life to exist in the first place (protective magnetic field, large moon, ozone layer, Jupiter as a cosmic shield) and it doesn't sound too far-fetched to claim that intelligent life is extremely unlikely to evolve in this universe.

    We want to believe the universe was created for us to exist and live happily but in reality everything in it is actively trying to kill life because it's so fragile against what's happening outside and within planets themselves (e.g. volcanic activity, extreme tectonic activity, oxygen toxicity).

    • Yeah, I think the likelihood that highly intelligent life exists NOW on both Earth and another place, is slim. At least, within the Observable Universe.

      If you assume the non-observable universe is practically infinite, you can get around that, but then it doesn't matter since you could never even know they exist.

    • Yah, that sounds right. Any moment now an overlooked comet or asteroid could hit us, or some new disease could arise naturally and wipe us out. (Although it would have its work cut out to get the job done before our own lab-grown horrors win the race). I suspect that we will be done in by something far more subtle and less dramatic, such as steadily falling levels of intelligence (which have already begun to make themselves felt).

      • The way our tech works when we try to make sometime it's artificial so it doesn't last. After a few generations the changes breed out. You've been reading too much sci-fi and not enough sci papers...

        The asteroid thing is a problem though. We have the tech to stop them but we're too uncooperative to solve the problem... Also way too much short term greed at the top.

        But as for intelligent life, somebody's gotta be first and that might be us. But the way the math actually works even if we're not it's no

        Well, survival of the dumb is made really easy by the rich technological society we live in. From what I see today, intelligence doesn't appear to be an evolutionary advantage anymore; on the contrary, it looks like smarter people will have on average fewer children.

        Assuming this trend is real and continues, it may lead to a significant drop in average IQ. If this happens, there is a chance that humanity won't be able to maintain the caring society we live in anymore. The change will probably be catastrophi

      I think that extinction is what is required for the intelligence to develop. Evolution can get stuck into sub-optimal peak. Extinction resets this and allows to search for a higher peak.

      Unfortunately, this argument fails to allow one to assume "anywhere that CHONP, water, and energy meet, life will form", the common belief of the SETI crowd. Because the universe is awash in ice planets that contain liquid oceans in contact with rock underneath a protective ice crust and with ample sources of internal energy. These are highly stable environments over geologic timescales - much more stable than Earth. Are we to believe that life evolved on these countless bodies, and not one in our celestial neighborhood ultimately led to a spacefaring civilization? That cryovolcanism / fissures / etc never led to surface species on any of them? That no underwater species developed technological civilization that allowed it to explore past its crust, gaze out at the stars, discover that the universe is awash in worlds like theirs, and set out to reach them? That none had portions where land protruded above the ice? That none were on a world that underwent geological change that warmed up their planet?

      I just can't buy this argument. IMHO, abiogenesis itself has to be rare. Perhaps abiogenesis isn't as rare, and lots of life that does evolve stays trapped on its planet - but I still think abiogenesis must fundamentally be rare.

    • I'd guestimate the average rate of intelligent life is roughly about 10% per non-trivial galaxy. This would explain both the Fermi paradox on the "rural paradox".

      The fact that our local galaxy cluster is small and isolated suggests intelligent but aggressive life usually spreads quickly in larger clusters. We are not in an "average" galactic spot but in a rural area, keeping us safe...for now.

      If we were in a typical (bigger) cluster, we wouldn't be around pondering why we are alone, instead conquered or ass

      It's hard to grasp the enormity of the universe. The current estimate is that there are 200,000,000,000,000,000,000,000 (two billion trillion) stars in the observable universe. We have no way to estimate how much more universe there is beyond that. So how extremely unlikely? A billion to one? Then there's two trillion intelligent species out there. A trillion to one? Then there's two billion. A hundred trillion to one? Then it's only ten million. There's a least a hundred billion stars in our own galaxy, an

      • In principe you're playing the infinitesimally small number times near infinity on the question if intelligent life may have developed elsewhere in the universe.

        But playing this numbers game entices you to come up with claiming that a billion to one chance is a small chance. It isn't necessarily. At uni, a professor discussed digital signal transfer within a microprocessor. Clock speed 10 megahertz. (Yeah I know , old story.) How often will there be a problem if there's a ten million to one chance in this

  • If they find evidence of life several million light-years away, do they still consider making contact "soon" or they may update their expectations to "in a short while" ?
    • If they find evidence of life several million light-years away, do they still consider making contact "soon" or they may update their expectations to "in a short while" ?

      Especially since several million light years away means several million years ago. (Or does it? Now I'm confused. Help me, Professor Jeans!)

      • Imagine if dinosaurs had developed intelligence. How would they have fared during the Cretaceous-Paleogene extinction event? Or if a similar meteorite hit early humans? Evolution might never have reached the same species again.

      The problem with advanced life being abundant - as per the Drake Equation is:

      1) The Drake Equation tends to make people suggest that there are a vast number of spacefaring alien civilizations out there "somewhere".
      2) A spacefaring civilization has equal odds of having evolved before vs. after humans, so vast numbers before humans.
      3) Since celestial timescales are so long, most would have evolved hundreds of millions or even billions of years before humans.
      4) Thus, their technology would be mind-bogglingly advanced.
      5) Unless all of them had some motive not to expand, they could be expected to have expanded throughout the universe - with an upper limit on velocity of just under the speed of light.
      6) Thus they should have formed bubbles of civilization hundreds of millions or even billions of light years across.

      So where are these numerous galactic civilizations? Hence, the Fermi Paradox (and its numerous proposed solutions; the one I favour is simply "life DOESN'T just tend to form wherever there's CHONP, water and energy; it requires rare conditions")

      • I prefer the likelihood that highly intelligent life is simply vastly more unlikely to evolve and then not destroy itself immediately than Drake's Equation (or the factors/numbers people tend to insert into it) suggests to some people.

          My issue with that is that once you become significantly spacefaring, it becomes increasingly difficult for you to exterminate yourself. There's a relatively narrow window where the capability is there, but then it steadily diminishes as the species spreads out in space in all directions, assuming (as one should) that the speed of light is a hard, fast limit. How do you, Evil Overlord Bent On Extermination, kill off your species thousands of light years away? You don't even know where they are, have no da

          • by Swervin ( 836962 )
            Maybe the reason we don't see evidence of advanced civilizations is because there's someplace "better" to be that we don't have access to yet. It's possible that once you've been tooling around for a billion years doing intelligent civilization stuff you figure out how to engineer a universe that is more favorable life than our current universe. We do know that it sure seems like universes do have a definite starting point, based on the evidence provided by our universe.
          • Carefully engineered viruses could be awful. But again, highly unlikely to get a total kill.

            Oh yes, they absolutely are that deadly. COVID? Zombies? Not one of them has anything on what a weaponized smallpox or the cocktail of weaponized bioweapons rouge nations like North Korea could unleash and has reportedly invested heavily in for many decades as an asymmetrical form of warfare.

            The Chinese are also believed to be working on genetically targeted weaponized viruses, designed for genocide of non-Chinese ethnicities.

    "Scientists with Breakthrough Listen... say a host of technological developments are about to transform the search for intelligent life in the cosmos.

    So what are these amazing, wonderful "technological developments"?

    "There are amazing technologies that are under development, such as the construction of huge new telescopes in Chile, Africa and Australia, as well as developments in AI," said astronomer Steve Croft, a project scientist with Breakthrough Listen.

    Ah. I see. Big telescopes and clever software. Stunning, radically innovative technical breakthroughs. Which will no doubt cost a very great deal, some of which may rub off on "Breakthrough Listen".

    But where is the "host of technological developments"?

      The fact that you don't understand their significance to the field doesn't change their significance to the field. Yes, they are talking about exponential improvements in abilities.

      • The article doesn't back up the claim of new technologies.

        New technologies may indeed have been needed to build these new large arrays, but those technologies are not discussed in the article.

        Therefore it is only clickbait.

    • I love your sig, and as a solipsist I think it was very clever of me to come up with that for you.
  • It's only as carbon free as the energy used to make it. Most energy still comes from carbon based sources. This might be a good process for living in space where we will not have the room for cows. Also a byproduct would be oxygen something we will need in space. Any space station or ship in the inner solar system will most likely get nearly all their power from solar. Not very practical or cost effective here on earth. We should stick with cows.

    its neither amazing nor transformative

  • TFA speaks about airport radar or TV broadcasting. That would mean an advance civilisation at exactly the same technological stage as ours, modulo the time for EM waves to travel from them to us. That would be an extraordinary coincidence as another civilisation can as well be billions of years older than ours and use radically more advanced technology we cannot detect or even imagine.

As for intelligent life,  as you say Earth is an impossibly improbable  exception and makes you wonder .... The counterfactual probably requires a true hard-anthropic-principle. 
      • The proof that life is improbable is on Earth itself. There is no other life except that which is DNA based and traces back to LUCA. All life uses the same DNA to amino acid code, and the same nearly the same ribosome sequence. If life can just emerge easily, we should be seeing other non-DNA based life or at least life based on a different ribosomal code. Instead all bacteria, and all eukaryotes have nearly the same ribosomal code and even genes in the animals don't differ by much. Some say that's because

Creating eukaryotes (and all complexity) through endosymbiosis, however, appears to be extremely rare and uncommon, as it only happened once. Even more rare is an impossible chain of events which led to intelligent life.
  • Evidence of life - as we know it - would be hard to hide once we achieve the technology to detect earth sized planets directly and measure their atmosphere.

    Evidence of intelligent - which is to say, technology using intelligent - life would rely on, at least for the moment, detection of electromagnetic radiation from far, far away. But let's look at how we emit electromagnetic radiation into space.
