SETI Founder Outlines Ambitious Future Plans

Lanxon writes "'In the universe there is intelligent life, I'm confident about that,' SETI founder Dr Frank Drake (of the Drake Equation) affirmed earlier today during a talk at the Royal Society in London, 50 years after SETI was founded. One of his visions to prove this, and to show that the last five decades were not a waste of time, is to station a radio observatory not in near-Earth orbit, but on the far side of the moon. He also suggests that another craft could later be stationed 500 times further away from the Sun than the Earth, using the Sun itself as a giant magnifying lens to resolve alien worlds."

    I personally think SETI is misguided, even though its aims are commendable. There probably is intelligent life out there, but it is a possibility that earth could have been the first planet on which it developed.

    But I see two very great problems with SETI.

    First is the limited range; nobody more than around 150 light years away would be able to detect intelligent life on earth.

    If we do find them they're likely to be more intelligent than us, they may turn out to be hostile, and they may discover that we are tasty, or good speceship fuel, etc. They may be intelligent enough that we don't even appear sentient to them. I'm not sure I want us to find intelligent extraterrestrials.

      You seem to share Hawking's delusion that more intelligence is an inevitable part of the progression of an intelligent species.

      Which is clearly wrong. Crocodiles, for example are as smart as they need to be. I think early humans were trapped into a (say) software intensive architecture. They had these tools (fingers, eyes, etc) which could only be used for survival by a powerful brain. So there was selection pressure for intelligence, but only because our peripherals (so to speak) had previously developed into general purpose tools.

      There's no reasonable explanation for why they would want to enslave us, or eat us, or otherwise exploit us.

      It's conceivable that they might want to wipe us out and repurpose Earth, as it does have some useful minerals, but especially given our nuclear arsenal and the (minor) headaches that would cause, I don't see why they'd go for Earth over the many uninhabited rocks in the universe. Direct harvesting of solar energy would be far more effective than exploiting us, whatever their goals are. We're far less useful than robots.

      I'm sure the people of South America, with all the environmental problems they were having, probably thought the same. But the Spaniards saw value in stuff that the Incas and Aztecs took for granted. Who's to say that ET won't come here and take a liking to our stocks of salt water for reasons unbeknownst to us?

      >> First is the limited range; nobody more than around 150 light years away would be able to detect intelligent life on earth.

      I have to agree with that one. It seems somewhat futile given the extremely low odds of detection. Furthermore, it seems hard to imagine we could really have meaningful exchanges with a civilization hundreds of lightyears away. That being said, if we ever did discover evidence of alien intelligence elsewhere in the universe, it would change alot of things here on earth. It would give a huge morale boost to many science fields, for one.

      >> they may turn out to be hostile

      Someone else said that "there is no reason to assume they wouldn't be hostile. I would say there is. Whenever I see the Klingon on Star Trek act in violent and barbaric ways, I wonder if it really is realistic to assume such a society could ever compete with a more "peaceful" one like the federation, on the technological level. If your society is full of violent individuals, places "being a strong warrior" above everything else, and you can get randomly killed at any time, I think that slows down scientific progress alot. In my opinion, individuals need to be "peaceful" enough for society to be rather stable in order for science to progress. Furthermore, a scientifically advanced society would probably realize that there is not much point in simply eradicating other life forms "for fun".

      >> and they may discover that we are tasty, or good speceship fuel, etc.

      I wouldn't worry too much about that either. If they actually are capable of getting here, it means they can get to any other nearby star. They probably have already mastered things like nuclear fusion, in which case, you know, hydrogen is the most abundant element in the universe. Energy itself, in this universe, is abundant. THE resource we have that is worth something is the earth itself, but it's only worth something to aliens, in my opinion, if they are biologically similar to us (breathe oxygen, similar temperature tolerances, etc.). Again, however, I would argue that if they have the capability of getting here, they are probably not "starved" in terms of energy. They would probably be capable of building themselves a new planet next to ours.

      >> They may be intelligent enough that we don't even appear sentient to them. I'm not sure I want us to find intelligent extraterrestrials.

      I find that idea rather ridiculous. We are sentient. Do you think there is something such as being "supersentient"?

      The difference here is that we have nukes, which function well as a sort of universal trump card. It's likely that our arsenal would at least inconvenience them, but it could do much more. Of course, it could also do much less.

      Our arsenal as it stands now would be pretty useless for repelling aggressive space invaders. They could just lob chunks of rock at us from high orbit or the moon while being essentially immune to retaliation. Hypothetically we could design rockets designed to carry nuclear warheads that far, but we'd still be at a crazy disadvantage versus the opponent who could just drop things down our gravity well.

      But it wouldn't do much less to our planet. If we saw an unstoppable alien aggressor, we could threaten to nuke ourselves. Sure, we may all die, but it'd still be a major bargaining chip.

      Only if what they wanted was us, or some other aspect of life on earth rather than other resources. But yeah, in some cases threatening suicide can be a useful gambit.

      Scientific discovery generally does much better in an open, cooperative society. I'm not saying that it's impossible without one, just that it proceeds much slower. Space-faring species would very likely have nearly species-wide cooperation in their past.

      Possibly, but that doesn't mean they automatically think of any other species as equals that should be cooperated with, rather than exploited. The scientific advancement and open sharing that characterized The Enlightenment was not extended to the people of places the empires of Enlightenment Europe went and colonized. They could just as easily see us as a bunch of hairless primates who don't deserve to take part in their glorious undertakings.

      Also, the universe doesn't quite seem to be teeming with life, or we'd have seen it by now.

      Way premature to say that. Our solar system isn't teeming with obvious life, but we've only just begun to be able to find exoplanets, and spectroscopy of such planets to find basic aspects of their chemical makeups is in its infancy. We're quite a way from being able to say these planets aren't teeming with life.

      The intellegence needed for space travel almost has to imply a sense of the beauty of the universe, and from there, life.

      Or, the sheer determination and practicality required for space travel -- especially if it's multi-generational sub-light-speed interstellar travel -- could imply a complete dedication to their goals and disregard for any of our silly philosophical objections like "but life is precious!"

      Look at it this way -- sea travel requires quite a bit of intelligence, yet after months of travel people landed on the other shore and their first thought wasn't "wow, look at the beauty of life!", it was "wow, these savages have lots of gold, let's take it!"

      I'd like to think the Golden Rule applies. Maybe that's naive, but interstellar travel is one of the milestones of scientific acheivement. I hope that that implies some moral strength.

      Societal advancement gave the Spaniards a sense of moral strength too.

      I don't think it's at all the case that achieving some milestone in science implies any measure of morality. So in that sense I do think you're being extremely naive. However I may be naive too in that I hope that we can develop moral strength alongside our technological strength, and that we will see beauty in the the universe and in life ourselves. But I don't think it's a given for us, and certainly not for any alien race.

They are quite possibly using something like lasers, x-rays, gravity waves, etc. True, if they are in the same stage we are, they may be using lots of the radio spectrum, but that greatly limits the kind and number of civilizations we may detect.

      We have a decent enough understanding of the laws of physics to have a good idea what would be a useful method of communication and what wouldn't be. For example, you list X-rays. But X-rays are much higher energy than radiowaves so are impractical. Lasers, which you also list, only work if you have a very precisely aimed beam. Unfortunately, when you are talking about distance of lightyears, a tiny bit off and your laser would be useless. (Incidentally, for technical reasons a maser rather than a laser would actually probably work better for this purpose). Even if they are using precisely aimed lasers, we won't be able to detect. Gravity waves are not going to be very good to send signals because they are incredibly hard to detect so even if you had a good way of making them, (which would also potentially lead to other cool stuff like anti-grav tech and potentially warp drive like technology) they would likely be extremely low bandwith. And we would have likely detected them by now in our searches for gravity waves.

      It isn't clear how we would go about detecting things like a Dyson sphere so that suggestion is out. There are some potential signs of large scale solar system construction that we can hypothesize. However, of those we could search for, we don't see any of them. Radio waves remain our best hope for finding signs of other civilizations.

    The problem with intelligent civilizations is that a few decades after they achieve a technological level where they can make powerful radios to talk to galactic neighbors, they also invariably build particle accelerators. These accelerators soon make micro black holes that eat up the planet and the not-so-intelligent civilization with it. Only 0.1% of intelligent civilizations survive by colonizing a nearby planet before the particle accelerator is turned on.
