SETI may be looking in the wrong places: astronomer
August 24, 2010 by Lin Edwards
(PhysOrg.com) -- A senior astronomer with the Search for ExtraTerrestrial Intelligence (SETI) Institute, Dr Seth Shostak, has reported in an article published online that perhaps we should be seeking alien "life forms" that are thinking machines instead of concentrating the search on biological life forms.
Dr Shostak said current experiments aiming to locate extraterrestrial intelligence all assume it is most likely to be found on "habitable worlds" with liquid surface water and light gaseous atmospheres, in other words, worlds that could support life similar biochemically to that on Earth.
The problem with this assumption is that the development of artificial intelligence may come soon after the invention of communication technologies, as it has for us, which means SETI's targeted searches may be "chasing a very short-lived prey," Dr Shostak said. We have a chance of detecting extraterrestrial intelligences once they invent radio and go on the air, but within a few hundred years they are likely to invent their thinking machine successors.
Like many other researchers, Shostak is unconcerned about the kind of extraterrestrial intelligence we find, and therefore restricting the search to biological life forms is unnecessarily limiting. The odds of finding artificial intelligence are greater than finding intelligent biological life, he said, although the decoding of any messages from a sentient machine might be more difficult than signals from a biological source.
SETI has been searching for radio signals from other planets and moons for 50 years, and its researchers have realized that as our technology is rapidly advancing, so might that of other civilizations, so we are searching for an evolutionary moving target.
Dr Shostak suggested the search for artificial intelligence should focus for at least some of the time on places were matter and energy are plentiful, such as young, hot stars, or near the center of galaxies, since these places would be of more interest to intelligent machines, even though they would be inhospitable for biological life forms.
The article was published online in Acta Astronautica on 7 July. Shostak also presented his ideas in Daejeon in the Republic of Korea in October 2009 at the 60th International Astronautical Congress.

I don't know what that means in reference to what I said. However:
A) We don't know where the aliens are.
B) If they are out there and signaling, why would we look in places where we're almost guaranteed not to be able to detect their signals compared to places where detection is easier and just as likely (given we don't have any real idea where to look).
C) Given limited resources, funding and points A & B, I'd be picking targets with a high signal to noise ratio.
All the more reason to look at minimally noisy targets. But I doubt we could ever detect signal leakage - they would have to be sending out a targeted beacon signal (ie, a deliberate transmission designed to attract our attention).

One thing on topic that occurred to me which you may want to consider... As there is no evidence whatsoever that the major things described in the bible happened at all, at least not HERE... perhaps they occurred elsewhere?
Most xians accept nowadays that the bible fables are mostly parables, allegory. Moses' staff didnt really turn into a snake, he didnt really part the sea of reeds/yam suph:
http://en.wikiped...Yam_Suph
-But those things which the bible claims undeniably happened- exodus, joshua, solomon/david kingdoms, etc- left absolutely no trace whatsoever... at least not HERE.
So you may consider that these tales were actually about furry little ewoks or giraffe people on some eden far far away, and were given to us in one grand peice of historical fiction. For us to learn humility.

However, it doesn't take too much intelligence to be a slave master and slaves have always been used to do what either the master can't or won't. And intelligent life would be the perfect slave for a semi-intelligent machine culture.

If you limit the range of suffering, due to a single person's actions, to the planet why not just limit that suffering and punishment to the individual who performed the action. The reason why you don't is because if there was no original sin, those of us who actually recognize our inherent morality and ethics would have no reason to join the God club. This is why atheism has come about kev. We recognize that we're not born broken, and in our humble opinion, we have no need of being "saved" from ourselves.

Scientific method (literally the method of Science) refers to a body of techniques for investigating phenomena, acquiring new knowledge, or correcting and integrating previous knowledge.[1] To be termed scientific, a method of inquiry must be based on gathering observable, empirical and measurable evidence subject to specific principles of reasoning.[2] A scientific method consists of the collection of data through observation and experimentation, and the formulation and testing of hypotheses.[3]

The fact of the matter is if a scientist takes any book, any book at all, and takes that book as the only unequivical facts in the universe, no matter what he/she sees throughout their life.... you can never use the scientific method.

Very good question.
I do not know about pick up the signal, to our instruments that message could appear as nothing more than background microwave noise. However, to me, they are talking about decrypting(decoding) the message. As it stands breaking some digital encryptions are getting harder and harder requiring some serious hardware to do so. I've already seen an article about quantum encryption making it "impossible", at least with OUR current technology. The Article proposes an artificial intelligence that will be very well versed in its own communication abilities and a long history of knowledge about its predecessors communication abilities and limitations.

Given limited resources and our current technology, it makes the most sense to concentrate those resources on locations that we can get the least ambiguous signals from.
I have a key problem with the article - it assumes that artificial intelligences will be particularly attracted to areas of dense matter and energy, like the center of our galaxy.
Why, exactly, would that be? The article is anthropomorphisizing(sp?) an alien AI. What if...
The alien AI was developed by a warrior-like species and so specifically seeks out biology-friendly environments?
The alien AI is itself organic and lacks the shielding to go to the center of the galaxy.
The AI has a life span of a few thousand years and FTL travel doesn't exist to take it somewhere so "interesting"?
To get a good view of the densly packed area, the AI has moved to a point that is not densely packed, say perpindicular to the plane of the galaxy?

The species is a design pushed beyond its normal limits and further weakened by unnatural selection. Like the german shepherd with its weak hind quarters or the fainting goat, our brains have gotten too big, too delicate, too prone to dysfunction and degradation.
Thats one reason why augmentation, followed by replacement, is inevitable; our flaws demand it. We are tired of being too smart and too general-purpose. Overactive immune systems in response to diseases borne of overcrowding leave us itching, aching, swelling. Unnatural fears of possible futures which the other animals cant conjure make us greedy and spiteful.
Is it any wonder we use god and the other drugs to escape it all?

That's why digital is easier to pick up. You either see the square wave or you don't (could also be another wave). But in a binary digital system, you'd see the DISCRETE ups and downs between the voltage... nature doesn't produce this, at least not usually. I guess a pulsar spinning super super fast might... but that would be easy enough to identify.. Seeing a digital single coming from a typical star, whether encrypted or not, would be plenty of evidence.... Boy, I'd love to be the guy to decrypt an alien signal... "How to serve man". lol

We are working on Quantum computers capable of using atoms as (qubit) states. Who knows what an galactic alien race would have.

I must interject that I agree and disagree with both view points here. My only model however is humanity. A very old ancient alien race who has solved all of its resource problems I doubt will be hostile, I also doubt given its age it would not be mindful of other fledgling alien races. After all humanity itself has thought up ideas such as Star Treks ban against interfering with underdeveloped planets, who is to say aliens have not thought of similar ideas and implemented them. However I also believe younger alien races would probably be more variable in hostility, similar to if humanity where to discover FTL Space travel in the next 20 years.

God, and Jesus as a consequence has LIFE in Himself and is able to give it to whoever He pleases.

One such noteworthy critter is the Tardigrades which can survive the vacuum and intense radiation of space for about 10 days. Life is an amazing thing composed of all the basic elements of the universe. It has a tenancy to adapt to prolonged moderate exposure to things over several generations as long as it has the proper resources to do so. (The key is the moderate part, it has to be able to survive and produce offspring) I believe given enough time, life can accomplish just about anything.

However given enough computing power this concept could carry into voxels. Add some basic physics and you have an atom based 3D game.

Most of us here are well aware of the Dark-side of Religion.
I did have one thought on this after wards, neutron stars on occasion speed up and slow down(their period is always unique). I think it would be plausible that if they where indeed used as navigation points something would be monitoring this. After all if we have had this idea, surely a space faring alien race would have as well.

I too have had this thought, as technology begins advancing faster and faster we start dabbling in more experimental and dangerous sciences. They could be our own destruction or our greatest triumph. It seems to be a balancing act really. On one hand we should be mindful of the consequences of our actions and research, and on the other hand we shouldn't be over cautious and nothing ever gets done.

Might want to check out this widely discussed paper on interstellar archaeology: http://lss.fnal.g...7-ad.pdf
From the abstract:
"A variety of interstellar archaeology signatures are discussed including non-natural planetary atmospheric constituents, stellar doping with isotopes of nuclear wastes, Dyson spheres, as well as signatures of stellar and galactic-scale engineering. The concept of a Fermi bubble due to interstellar migration is introduced in the discussion of galactic signatures. These potential interstellar archaeological signatures are classified using the Kardashev scale. A modified Drake equation is used to evaluate the relative challenges of finding various sources"

In the paper I linked, Section 5 on looking at exoplanet atmospheres in the search for ETI especially timely, in light of the recent CoRoT and Kepler findings (the missions are discussed here). Looking for clearly synthetic or unnatural molecules (like, say, Freon) in the atmospheres of exoplanets should be achievable in the near term (~20 years), and there is a good discussion of the process. There is also mention of Hubble's recent detection of sodium in the atmosphere of Osiris b, a crucial first step in this direction.
Section 7 deals with looking for spectral signatures of Dyson Spheres and Dyson Shrouds with infrared surveys. A preliminary search of a few regions of the sky using the 2MASS IR survey has been undertaken and results of these searches are discussed, along with a list of objects that may have similar spectral signatures (false positives).
Overall, it's a speculative paper, but many interesting ideas are discussed.

We have missing links and no true understanding of how we developed so fast or the real reason why the last hundred and twenty years or so many advancments have been made. The old saying there is nothing new under the sun, except fax machines,cell phones and a billion other modern devices and discoverys.
I would think most people would realize they are all ready here.
Aliens look at us the same way we look at white tigers in the wild. Preservation and conservation with as little disruption of the tigers daily life.
I would think us grabing a lion to do testing on him is just as scarry for him as a person being abducted by aliens. I bet his lion friends do not belive him when he gets back.lol.

2. Likely, the only types of life that we might have to fear would be those that evolved in a similar environment to Earth's, or, that needed as a vital resource, some by-product of biological activity(though that seems unlikely).
3. Certainly, by the time that a lifeform was sufficiently evolved to become spacetime faring, they will have conquered their resource needs, and given the abundance of raw materials throughout the universe, it seems unthinkable that they would need terrrestrial resources. Except for in the case of a lifeform that was so entirely different from us as to not recognise us as life at all- again, highly unlikely.
4. SETI should be looking for periodicity in ALL wavelengths, as period is the only thing that would distinguish communication from noise.

And the scale of this communication could also lie anywhere along the curve, from a few light years, to across the universe, and could include the use of stellar- or galactic-scale objects.
5. Ultimately, given the above reasons, it would seem most likely that ET would be searching for intelligence in order to avoid loneliness. There doesn't seem to be any reason for aggression, except for in the case of a lifeform that has evolved technology while still remaining almost entirely, and brutally, internally competitive, in the Darwinistic sense- but this in itself seems unlikely, although it remains a possibility. The other option of agression would likely be some type of biologically-enabled spacefaring organism, organised in a bacteria-like way, and perhaps nearly mindless -a ravenous hive-thing. To be feared.
6. I say, let's keep looking, but necessarily, we should keep developing our own defensive tech, and pushing to get offworld.

7. As far as AI and transhumanism are concerned, I think it is important to remember that any AI we develop had better be subservient to humanity, and hopefully will encompass enough computational power and research ability to be able to solve most or all of the problems facing us in the quest to upload into Space.
The transhuman notion is all fine and dandy, but I believe it would fundamentally alter what it is to be human, -which may or mayn't be a good thing, but, for myself, and for now, I think I would prefer XXXFTL travel, and some sort of field-generating device that could negate or normalize gravity, radiation, temperature, pressure and other environmental/biotic factors(and including some type of nano- or self- regenerating capacity), while still allowing us to remain substantially human in form and function. The only other reasonable option would be to go 100% synthetic with enhanced sensory capacity, which could also be enabled for the non-synthetic human.

As for Shostak he needs to take a good long cold shower or spend more time with his psychiatrist.
Artificial Intelligence is feasible but it remains a very, very long way off. We have to understand the nature of intelligence before we can create an artificial version and at present we are still in the earliest and darkest of dark ages as far as our ability to understand the nature of intelligence is concerned.
Computer idiots are always claiming to be developing forms of artificial intelligence but all their best efforts are simply sets of decision gates there is not one iota of intellect in any of them.

Some thoughts: 1.) If ET's exist as space faring entities, wouldn't they tend to stay away from the gravity wells? After all, there are extensive resources out in our Oort cloud well in excess than our measly planets could supply. 2.) Biological life "out there" is a virtual certainly, what with all the precursors floating around out there. They fell to Earth, got zapped by lightning, sitrred up in the primoridal soup and voila! Doesn't seem difficult to me to imagine that the universe is teaming with life. 3.) If you accept that conjecture, any life, especially microbial, is likely to be rather dangerous. Human and ET life evolved over billions of years without mutual contact, and could be highly reactive to each other. I just hope our immune systems are up to the task when we land on Mars/Europa. 4.) Bacteria do not require Earth-like environments. (cont.)

If you can cut a single photon in half and take one half to the space station and keep the other half in a lab here on earth, as you alter one half of the photon the other half changes to match instantly. So what connection keeps them together even though as we see it they are in two diffrent locations. If there is some string like connection to atoms maybe that is the future of communication or travel that will come from learning what path the information is taking to tell the atom to change.
The idea that the speed of light is the way to travel is like cave man telling you how to fly.

Barring that unusual theory, why not chemical? Ants and other hive insects use chemical communication to cooperate and maintain order.

That might give those life forms an advantage over us but they still need a sealed, shielded atmosphere and nutrition for the journey. A machine does away with all that.

I am an atheist but once upon a time I was housemates with a fellow. He was vastly intelligent; he loved science, he had a fine sense of humour; was kind and soft spoken and patient, but also a devoted father and Christian. Nothing switched on his rage like Creationists and their theory Intelligent Design.
Like him, ID fills me with horror at this vast, unthinking arrogance of willful ignorance.

Seriously, if we develop the technology to make robots of that degree of sophistication, then my guess is that we'd have also developed the technology to overcome the problems of resource issues for human space travel.
It's not a 100% sure thing, but let me ask you this- if you were given the chance, would you go into space? I know I would. I don't really expect that desire to be lessened any in the coming years, and I believe that science will find a way to get humanity into space.

Sadly it does not look so for our race.

True, but I'd imagine it would depend on the alien's technological evolution. Using nano-machines an AI robot can appear as every bit 'biological' as... well us, the biological machines. Even give them better healing, faster replication, and tougher armor. They'd just need a store of raw material to do the jobs... like us.
Of course to truly manipulate DNA you need extremely complex equipment, which I'd also imagine that the best instruments to do the job would be nano-machines.
