SETI Predicts We'll Find ETs by 2020
FTL writes "Based on the Drake Equation, Moore's Law, and the Allen Telescope, a new prediction has been made that Earth will make first contact with aliens within 20 years. Of course once we find the first aliens there's the question of can we decode their signals, would they spot our reply, and what's the lag time."
And I predict that I'll get laid by 2020....
I'm glad "sending a radio message back will take centuries," because I'm not sure that a response back of "humans on earth, eh? we'll be right over," is a Good Thing (TM).
"...all the labours of the ages, all the devotion, all the inspiration, all the noonday brightness..." yada yada
...and monkeys will start walking erect, too.
Oh, wait.
How good are they at Counter Strike.
I could be wrong.
I've seen it at least 10 times since it's first release. I'm starting to get sick of Elliot's whinning.
Kiss my bass.
It would really complicate matters if they don't have the technology to generate emag signals.
This calculation doesn't include the number of people turned off from the SETI@Home project by the new BOINC software.
ET finds YOU!
It is 2004, right? Wouldn't that set the date to 2024?
there's the question of can we decode their signals, would they spot our reply, and what's the lag time
And is their primary goal "To Serve Mankind?"...
2020, just in time to send my first and brightest to Battle School.
And SETI predicts a healthy funding increase owing to this PR stunt.
We're already here.
The green alien babes don't want you, either...
... they don't find us first?
The more important question is, will they be friendly?
"A truly wise man realizes he knows nothing."
Of course, if we ever find these ETs, at the rate Congress is cutting NASA's budget, we'll never be able to meet up with them unless they come to us.
Shostak assumed that computer processing power will continue to double every 18 months until 2015- as it has done for the past 40 years. From then on, he assumes a more conservative doubling time of 36 months as transistors get too small to scale down as easily as they have till now.
As has been seen with 65nm Prescotts and difficulties with die shrinks to this size by IBM and AMD as well, we may already be at or near the point that they had assumed for 2015.

SETI says 2020, so now we have a new Internet deadline to watch. I bet they strike gold next year sometime or the year after. And when they do, I bet the Aliens look like giant chickens and they kick our asses for KFC.

...they use linux?
A misleading article summary on /.? I'm shocked and appalled!
A better way to state this story is that within 20 years, SETI will have the capacity to detect transmissions from across our galaxy, rather than just a small slice of it. Whether or not there's any signal to pick up is another matter entirely...
Stop by my site where I write about ERP systems & more
I'm pretty sure ET has already found me. At least, that's what the grey midget sticking the cattle prod up my ass while covering me in slimy Saran Wrap told me through my mind the other night when I was snatched out of bed via a beam of light.
Wait -- never mind -- that was Tequila talking after some really bad Mexican food. No wonder my ass hurts. Damn that Mexican midget waitress!

Of course once we find the first aliens there's the question of can we decode their signals, would they spot our reply, and what's the lag time.
and whether they've got the latest levels.

"We are the Borg. You will be assimilated. Your biological and technological distinctiveness will be added to our own. Resistance is futile."
will they get sued by SCO?
Doesn't this imply they believe that alien life is thousands of years ahead of us in technology?
Consider this paragraph:
Within a generation, radio emissions from enough stars will be observed and analysed to find the first alien civilisation, Shostak estimates. But because they will probably be between 200 and 1000 light years away, sending a radio message back will take centuries.
Ok, if they are on roughly the same time line we are, they'd have to have sent the messages 200 to 1000 years ago for us to GET the messages. It works both ways, they have to be AHEAD of us, significantly, to say that just because we're ready to hear them, if they exist, they'll have a message for us to hear.
Never confuse volume with power.
Is simply detecting intelligent life way out there 'contact'? Seems to me 'contact' is mutual recognition of one another's existence. That is, knowing they're there while they are oblivious to us isn't really 'contact'.
try { do() || do_not(); } catch (JediException err) { yoda(err); }
Within 20 years.. and it's 2004 right now.
This is pretty complicated let me pull out my slide rule:
2004 + 20 = 2024
So the topic should be "Seti Predicts We'll Find ETs by 2024"

that by 2020 they will have changed the prediction 100 times because they keep discovering their assumptions are wrong. But they will refuse to give up wasting their time searching for the non-existent.
Borrow money from a pessimist - they don't expect it back.
... are there actually aliens to find?!
Then, even if there are, had they advanced enough to send out the signals we can detect, long enough ago for those signals to reach us?
That there is a big difference between making "first contact" and "detecting their transmissions".
We could stumble across a repeating, non-natural signal tomorrow, and granted this would be one of the top 3 (if not the greatest) scientific discovery ever, but it is unlikely we would be able to do anything with this discovery for a very, very long time. Understanding the message would probably take decades, sending a reply would take light years, and holding any kind of meaningful communication would require technology totally and completely beyond our current levels.

Just as irrigation is the lifeblood of the Southwest, lifeblood is the soup of cannibals. -- Jack Handy
Making the large assumption that an alien race will go through a similar radio transmission curve, and considering the fact that we don't know how far away said alien civilization is, the chances of us finding them between now and 2020 seems very remote.
From the first sentence of TFA:
If Intelligent life exists elsewhere in our galaxy, advances in computer processing power and radio telescope technology will ensure we detect their transmissions within two decades (my emphasis)
Even if ETs do exist, there are a host of long-standing doubts about whether they'll be using "transmissions" (questionable), or whether those transmissions will be distinguishable from random noise (OK, probably).

They don't really "predict" anything. Just because it's based on some other theories doesn't suddenly mean we really will contact aliens in 20 years just because they said so. Organizations like to make vague, arbitrary predictions like this to stir up publicity. It's like when "experts" make claims that we'll have robot servents by 2012. It's meaningless.
...one, someone keeps paying to listen (not a guarantee, but I hope it happens) and two, there's somone out there for us to here. If there isn't, it sure is an awful waste of space, seeing as how we're not exactly jumping to fill it. But that's another matter entirely.

If there were, the Bible would not say that "man" was created in gods image. It would say "man and others". The Bible is clear that we are the only forms out there, and that all other areas were made for us. We would be all over the universe now if it were not for The Fall, which is something we should all regret and strive to make up for.
Why would an advanced technology use a method limited to the speed of light to communicate across the galaxy?
SETI brings to mind a picture of some remote tribe looking for smoke signals as a sign of intelligent communication while standing next to a satellite dish.
Well probably have to annialate them once we find them can't have any threats out there in space and find aliens by 2020 I am glad they aren't setting a realistic goal ??????
Come on - how many others thought "Shostak? Is that some made-up alien name from a science fiction show on at 3 a.m. on a cable channel?"

Now that sounds like a safe prediciton. Rather like the we'll have flat-screen televisions that we just unroll and hang on the wall in 5 years that I've been hearing for the past twenty.
Seriously though, the idea that life must exist elsewhere, and will communicate in a method we can detect across interstellar distances, is still just that -- a theory.

It will be 2047. The'll come fleeing another race. We'll build lots of stuff with them. And then the other race will come to hunt us both down. 300 years later, the earth is destroyed and we're homeless. But we also take back most of the known space about 10 years after that.

Usually it comes in 10 to 15 years. In this case it must take the signal an extra 5 years to get here. Either that, or someone can't do arithmetic.

If the time it takes for a signal to get to us from then is really big, then wont the first things we would hear from them, be like their first radio broadcasts ever?
I mean I would assume that the frst thing that aliens would hear from us would be early radio broadcasts, wouldnt the first thing we hear from anyone be the same?
I think SETI should be a permanent project of man kind. SETI's search is not merely science, it is a philosophical matter of the highest importance.
The day this happens will change the way minkind think's forever.
I've been wondering this...and all of you people that think you're smart might be able to figure this out for me. SETI uses radio telescopes to search for E.T., right? Now, I understand that these radio telescopes don't just search for AM/FM radio signals, but basically waves within the full broadcast spectrum. So they're looking for AM/FM, TV, CB, Wi-Fi, wide band, short, wave, cell phones, etc. So I guess the basic thinking is that any intelligent race will use radio signals of some sort. How long have humans been using some kind of radio signals? In the general scheme of things, a very brief time. How much longer will we be using them? Is this something that will be with us forever, or will it die out as our technology advances? Assuming our technology will advance, somehow, to exclude broadcast signals, our planet, from space, will become rather quiet. Also assuming that all intelligent life evolves along a similar timeline, we can assume that these other planets will emit radio signals for only a brief period of time. But somehow we're assuming that that time will somehow coincide with our own. It makes finding a needle in a haystack even harder when the damned needle keeps moving around. Enlighten me. How can SETI possibly work? (That said, I do have the SETI@Home software running on all of my machines...so I'm hopeful.)
radio is too slow, what is it that the sun produces that travels way faster than light and goes through everything? if anyone is out there, thats what they are using...what ever happened with that experimental thing they buried 1/2 mile underground filled with water to catch those things the sun produces?
my prediction? we will learn how to use that and will be connected to countless civs' (if they out there)
Contact could have been expected by 2010, but release of the BOINC software has delayed the seti@home project by at least 10 yers.

What an outlandish claim. This type of announcement reminds me of similar claims by Doomsday Churchs on precise dates when the Earth will be destroyed.

My point is, the Drake equation has so many variables that we can't even get a ballpark estimate of that any prediction based on it could easily be off by a couple of orders of magnitude.
If there are aliens on remote planets, it seems to me that it is extremely unlikely that they are at the same technological level that we are (either higher or lower), and since all of the pseudo-science / probability people say that there is an enormous chance that there is in fact life on other planets, it follows that if there is life 'out there', some of the civilizations must be extremely advanced compared to ours.
In that case, it is hard to believe that they are not aware of us. This is where you need to put on your tin foil hat. If they are aware of us, and have not contacted us, they clearly do not want us to contact them / be aware of them. If they have technology vastly superior to ours, isn't it possible they could filter out any signs of their existance - or even 'fine tune' our perceptions of the universe beyond removing just signs of their own existence?
you put the "nt" in the subject so people know not to open your comment. I realize its a difficult concept to grasp, but if you think about it for a while, it should make sense.
From the article: "Shostak came up with an estimate of between 10,000 and 1 million radio transmitters in the galaxy."
The Drake Equation is just a fancy way of saying SWAG (silly wild-ass guess). Personally, I find this SWAG to be wild high by several orders of magnitude.
Personally, my guess is that our galaxy has 0-5 other species actively transmitting.
The most rabid believers in American Exceptionalism are the exact same people whose policies are destroying it.

I am wondering what (if any) protocols have been formalised for how 'exactly' we will choose to interact with ET's. I read an article somwhere that plans were already drawn up covering what to do in the event of contact, but my brain is broken today, and i can't put a decent google together. Anyone know of these contingencies?
"Of course once we find the first aliens there's the question of can we decode their signals, would they spot our reply, and what's the lag time."
No.. the real question is whether they'll be interested in destroying our planet after they spot our reply.
"It would be wrong to refuse to face the fact that everything is fundamentally sick and sad."
While I like the idea of sending out ships with information, I do have to wonder about the wisdom of telling others exactly where we live. If we sent a ship out that did replies, I would have no issues.
I prefer the "u" in honour as it seems to be missing these days.
The idea of meeting aliens within 20 years is absurd. So many things can happend within twenty-years to change what may or may not be a precised prediction. For example, lets say a meteor slams into the alien's space ship due to USA's laser defense system which they had fun to use shooting at meteors and breaking them into smaller pieces.

That should take about 20 years right?

If we havent decimated our existence or environment by that time. On that note, it will be interesting to know if the ETs want us to find them. It's very likely they know we are here, and want nothing to do with us other than observe how we have pretty much fcked up 60 billion years of evolution in 100 years.

The problem with SETI fanatics is that they assume that aliens are using primitive EM waves to communicate. If EM waves were the only way to communicate, we would be bombarded with intelligent signals from all directions. I have a little advice for SETI. Aliens can communicate instantly using their knowledge of the non-local nature of the universe. Get a clue.

The good news: soon we'll discover the radio signals of an advanced alien civilization.
The bad news: their messages will likely be encrypted beyond comprehension so that we don't copy their programming and distribute it on P2P networks.

It is another matter, but Shostak also addressed it in his prediction:
So not only doese he think we'll have the capacity to detect the transmissions, he also predicts that the transmissions are just waiting there for us to pick up, based on the Drake Equation.

And if you don't mind a little neo-liberal dig here, the unrestrained market is a superior rational process to the scientific method for estimating likelihood of events occuring. Especially events which involve a great deal of uncertainty, divergence of opinion, and emotion.
Having said that, Mr. Shostak is boldly taking a stand by stating any sort of probability at all and I approve of it. It's very possible that this new information will change singificantly the odds on the Foresight Exchange as the traders digest it.
While the equation is clearly true since it's basically redundant, it may not elucidate the problem very well. This is because some of the terms may be nonlinearly coupled.
If interstellar propagation of a technological species is possible, the rate of emergence of such species is not independent of whether such species have emerged in the past. There is an ecological competition between hypothetical spacefaring species. Unless two such species emerge simultaneously and accomodate each other, the emergence of one will essentially foreclose the emergence of another.
If the rate of formation of stable technological civilizations is sufficiently low, and the rate of interstellar spread of such civilizations is sufficiently high, there will only be time for one such civilization to emerge per galaxy. By the time the second one could emerge, the first one would have filled the entire niche.
In this scenario, by virtue of the fact that we have emerged, we can conclude that no stable competitors have emerged yet.
In fact, my intuition is that the universe is in precisely this regime, and therefore that we are very unlikely to succeed in SETI.
mt
That actually covered by the fc and L factors. But it's still a useless equation.
If EM waves were the only way to communicate, we would be bombarded with intelligent signals from all directions.
At some level, but free space losses drop the signal levels until they get lost in the background noise, even in the microwave window. I design satcom links, and that's the biggest factor we fight: the signal attenuation simply due to distance. Hence, antennas in which you could land a small plane.

Proof? Easy. Look up The Fermi Paradox. One of the corollaries that convince me is the fact that, even at sublight speeds, it only takes 1-10 million years to fill up a galaxy, since a race would tend to fill up in a geometric progression. Given how old the galaxy is, it should have happened by now. It only takes one race in billions of years to have wanderlust for earth-like planets, and boom! No more intelligent life rising up.
That it hasn't seem to have happened means we are alone.

I'm not convinced that there is life outside of earth to find. Even more so, I really doubt that if we find another planet that harbors life, it will contain intelligent life. Scientists are just beginning to learn how unique our planet really is. Things such as our cosmic location to even our (relatively) overly large moon add into the stability of our planet. Also, (and this is more of my own opinion) intelligence seems to be overrated as far as what we see on earth. For instance, apes are among the most intelligent creatures on earth, yet they do not have radio communications. Ants, on the other hand, have been around for millenia, yet are very simple creatures. If intelligence was such an important factor to survival, I think we would see more animals on earth nearing human intelligence. I also believe in divine creation of humans, the idea of which, I think, is helped out by the fact that we are so unique amoung all the species on earth.

So, will it be anything like "Independence Day"?
supposing aliens are also listening for signals of aliens and they run into our noisy broadcast spectrum, how are they supposed to know what is just random chatter and an actual message?

2) Do they have oil? Maybe we can go to war with them...

4) How will the $3,500 DirectTV blood money be converted into their currency?
5) Will the patent office be flooded with new alien claims to gifs, automatic software download and Linux? Maybe aliens created ELF?
6) Will they be covertly tagged with RDIFs when they arrive, so they can be tracked by Walmart?
7) Are these the same aliens that are on Opra and Jerry Springer, which thrive in our trailer parks?
8) Will jobs be outsourced or "co-sourced" to their planet? Will I have to wait on hold for 6 hrs for someone to translate my problem?
9) Can they work 14 hr days? You know, because they would be salaried employees of course.
10) Are they democrats or republicans? You know we don't really like independants

What if they use a method of signal transmission totally foreign to our understanding of physics? 2. That THEY are listening. Just because we are preoccupied with finding extra-terrestrial life, that doesn't mean that THEY are. 3. That they would even respond. The assumption is that they are able to respond. It's very likely that even if we find intelligent life, it will be behind us or ahead of us in terms of technological development. If they are behind us, they may not be able to respond. If they are ahead of us, they may not feel we are worthy of a response. How much attention do we show to ants? Who says that ant crawling on your leg isn't trying to make contact.

The exponential nature of tech growth implies that we are like apes to a civilization even 100 years ahead of us, and like ants to one thousands or millions of years ahead of us.
Bullocks.
Are people from 100, 500, or 1,000 years ago "apes" to us? They didn't have all of the modern conveniences, but a lot of them did exist--and the average person, though less educated, was not a good deal less intelligent than they are today.
If they communicate with us, then come to attack us, we could always rely on creating a virus on a MAC that will take down their mother-ship. (Independence Day)

First Contact Within 20 Years: Shostak
Will the 20s see ET roar onto center stage
Mountain View CA (SPX) Jul 22, 2004
If Intelligent life exists elsewhere in our galaxy, advances in computer processing power and radio telescope technology will ensure we detect their transmissions within two decades. That's the bold prediction from a leading light at the Search for Extraterrestrial Intelligence Institute in Mountain View, California.
Seth Shostak, the SETI Institute's senior astronomer, based his prediction on accepted assumptions about the likelihood of alien civilisations existing, combined with projected increases in computing power.
Shostak, whose calculations will be published in a forthcoming edition of the space science journal Acta Astronautica, first estimated the number of alien civilisations in our galaxy that might currently be broadcasting radio signals.
For this he used a formula created in 1961 by astronomer Frank Drake which factors in aspects such the number of stars with planets, how many of those planets might be expected to have life, and so on. Shostak came up with an estimate of between 10,000 and 1 million radio transmitters in the galaxy.
To find them will involve observing and inspecting radio emissions from most of the galaxy's 100 billion stars

All this postulation about this space culture or that. But what if all the so called intelligent cultures are more or less at the same point we are - early 21st century give or take a thousand years. That would me that they about as blind to us as we are to them. Meaning that they might be far closer than say a million light years but because of their limited technology and power output they can't send a recognizable signal to us nor can they receive any recognizable signal from us.
Think of it this way - to some far off place the earth must look like one of a large collection of fairly strange radio sources that appear far more powerful than any natural occurence dictates they should be. But that raw output is pretty much all they would see, and that's only if they are practically next door. Much further than 50 light years away and we start to look postively preindustrial. So in order for us to find an intelligent source not only does it have to be fairly close to us it also has to be much more advanced else we would never see any nascent culture with barely the power or sophistication to transmit. Remember that is space distance equals time.
Umm, yeah. Because people at the turn of the LAST century were like apes to us...
However I do agree more with the second portion of your statement (Millions of years ahead, not thousands).
What's the critical factor between now and 2020?
Aliens, Aliens, Aliens, Aliens!
And, a 350 dish Allen telescope should be enough for anyone ;)
Any ET life that has the technological capacity to produce radio signals, will before long (say 200 years) be using compression to maximize transmission bandwidth. By definition, as compression gets more efficient, there is less apparent order to the signal. If there was any order left, in other words, you could compress the signal further.
The result is that the detectable light-sphere enamating for this ET civilization, effectively becomes a light-shell, with a thickness in light-years equal to the length of time between their widespread adoption of radio and its conversion to a maximally-compressed digital format (the generous 200 year window mentioned above).
Unless we were listening within that 200 year window, the signal is either still on it's way, or is past us. In other words, the likelihood of SETI detecting a signal is roughly equivalent to the chances that we're within 200 years of the ET's in development, adjusted for the time-of-propogation.
This assumes they're not trying to be detected by transmitting a naked pattern intentionally, but offers a good counterpoint to the "party line".
Simply phrased "Shot first, greet later!"

Now we will have all those quake addicts complaining about the ping of Alpha centuari!
Sorry if I seem a little pedantic here, but the summary is quite confusing. I know you can just RTFA to straighten it out, but I don't really think there's much excuse for having to. 2004 + 20 = 2024. Not 2020! That is a difference of 4 years. While 4 years might not seem like that much at first, think about it in terms of, say, your own life. If I die at the age of 80 (I figure that's a reasonable guess, right?), 4 years is 5 percent of my entire life!

First Contact Within 20 Years: Shostak

That's the bold prediction from a leading light at the Search for Extraterrestrial Intelligence Institute in Mountain View, California.
Seth Shostak, the SETI Institute's senior astronomer, based his prediction on accepted assumptions about the likelihood of alien civilisations existing, combined with projected increases in computing power.

Shostak came up with an estimate of between 10,000 and 1 million radio transmitters in the galaxy.
To find them will involve observing and inspecting radio emissions from most of the galaxy's 100 billion stars. The time necessary for this formidable task can be estimated from the capabilities of planned radio telescopes- such as SETI's 1-hectare Allen Telescope Array and the internationally run Square Kilometre Array- and expected increases in the power of the microchips that sift through radio signals from space.
Shostak assumed that computer processing power will continue to double every 18 months until 2015- as it has done for the past 40 years. From then on, he assumes a more conservative doubling time of 36 months as transistors get too small to scale down as easily as they have till now.
Within a generation, radio emissions from enough stars will be observed and analysed to find the first alien civilisation, Shostak estimates. But because they will probably be between 200 and 1000 light years away, sending a radio message back will take centuries.
Paul Shuch, executive director of the SETI League, a separate organisation in New Jersey, says Shostak's prediction ignores one important factor. "It is altogether reasonable to project the development of human technology, based upon past trends and planned investments," he says.
"But predicting the date, the decade or even the century of contact is another matter because the 'other end' of the communications link is completely out of our hands. It would be nice to think we know something about the existence, distribution, technology and motivation of our potential communications partners in space, but in fact, we don't."
Shostak admits that there are myriad uncertainties surrounding his prediction, but he defends the basis on which he made it. "I have made this prediction using the assumptions adopted by the SETI research community itself."
The Physics Of Extra-Terrestrial Civilizations
Moffett Field - Apr 27, 2004
To consider habitable worlds, advanced civilizations, and how to find and classify them, Astrobiology Magazine had the chance to discover from Dr. Michio Kaku that the laws of physics has much to say about such possibilities--at least much more than where you might expect speculation to lead you from our tiny corner of the universe.
... is the product of seven variables, only one of which can be scientifically even estimated. The remainder are guesswork and hope, so the probability of finding alien life forms, intelligent or otherwise, is directly related to your level of optimism. Personally, I'd like to find intelligent life somewhere, possibly even on this planet.
...wouldn't you still want to know?
-- http://frobnosticate.com
I want aliens that Captain Kirk can outmaneuver with Corbomite. Oh, and please include a bug in the program that locks it in an infinite loop when we ask it calculate the value of PI to the last digit, so we can make them all go away when we get tired of them.
The fact is, we are all aliens.
Over time, we have moved from planet to planet, depleting resources and moving on to the next... hence the differences in races, languages, religions, etc. This is also the reason the dinosaurs on Earth died off - we could not co-exist with them. Destroying them was the answer. Upon leaving a planet, our technology was always at a point to where we could manage to create life on the next.
Studies on Mars will uncover clues to this.
The answers will come in time.
The odds or our own existence are sigificantly paltry. The odds of intelligent life elsewhere are practically nil. Get to know your neighbor and forget about ET. The univerese is full of gas and empty rocks.
The green alien babes don't want you, either...
Those big blue gay aliens sure like you, though
Presesent Jenna Bush prepares a pre-emptive strike against Zebulon 5, rumored to be harboring WMD. "By gum, I just know they got 'em there somewhere. I can tell by the look in their beady little eyes, all three of 'em!"

I contemplated joining, but thought "what the hell, they may not even be approaching this right, why risk wasting CPU cycles on them?" Then I found out about Folding@Home, and am impressed with its goal. It actually will make a difference in the quality of human life by helping us fight more diseases.
SETI@Home might get us in touch with an alien race, but is that even desirable at this point? All of those people racing to contact ET forget that most of the abduction stories involving the "greys" are incredibly negative and traumatic. Do we really want to full open ourselves up to them others who may be just like them in their attitude toward human life?
Click here or a puppy gets stomped!
Purely from a logical viewpoint I find it very interesting that people expect all alien forms to be friendly. Yet it seems that people somehow got this idea that because they might be further evolved than us they would have to be peaceful.
Why would some other lifeform have better standards and ethics than us? Do we have statistics that say X% are friendly and Y% have proven to be hostile?
Just look at this one tiny planet. Are we very peaceful? Sure does not look that way to me. Have we waged less war the more we evolved we've become? Nah, we just got better at killing. A-bomb anyone?
We don't even have policy in place to stop things like Vietnam to occur. Just because money was involved (from the minerals). We lost 50,000 people while somone got a bunch of oil out of Sout Vietnam. And then later sailed up the coast and sold it to North Vietnam. So we now people do crazy things for money. No doubt about it.
Slavery, genicide it's all there...
So it just seems a bit too naive to just brush it off with "Oh aliens must be friendly!" They could be a lot better than us, but we don't have a clue if they are...
That makes it a bit dumb to send out probes that tells a potentially unfriendly aliens, and if they have the know how to come here, technically superior weaponry, all about us.
You see how quickly the military gets involved if there's a way to use a new technology for military purposes.
Anyway when I see friendly alien notes I always wonder what kind of logic was applied to arrive at that notion when there's no data to support that.
Stopped with the first sentence, huh?

Within a generation, radio emissions from enough stars will be observed and analysed to find the first alien civilisation, Shostak estimates

Let me pu tit this way... go to your local gas station, look at the prices, and ponder that we humans used to discard gasolene as a USELESS byproduct of kerosene manufacturing....
Really, this whole thing comes down t the assumption that A) we get really lucky and the critera you describe are met, or B) some more advanced civilization is wasting what we would consider to be humongous amounts of energy. It is rediculous to assume that just because our power output is at a certain level, that an alien race's power output would be equivalent.
If their anything like us, perhaps we should stop trying.
But we might be an abberation. The rest of the universe may be all "peace-groovy, brother" and we got saddled with the wingnuts. Probably not though.
the growth in cynicism and rebellion has not been without cause
"exponential nature" being the key point here folks.
That as we continue along our current path, the odds of our complete self destruction rise exponentally - to the point of being almost 100% certain.
That being said, any sufficiently advanced civ would either have to overcome this tendancy (if they share it) or we would never meet then.
Of course, this says nothing about how they would treat us, only how they treat each other.
Similarly, perhaps said races have been checking up on us ever 1,000 years or so. When they last visited in the 1400s, we were busy trying not to be killed by our own microbes, we couldn't comprehend electromagnetism, and couldn't even leave the surface of our own planet without a physical structure to support us. Maybe we'll show more promise next time around, assuming that we haven't managed to exterminate ourselves in the mean time.
Dewey, what part of this looks like authorities should be involved?
Or, our first intercept might be something like "If you can read this, you are too close, and we are dispatching the Vogon Constructor Fleet." ;)
Or how about, "....indicates that the new species is attempting to observe our communications. Shows tendency to grow without regard for available resources. Unstable, shows potential, frequently inflicts harm on itself and surrounding life forms. Please advise. ~Gloobanerb Exterminators, Inc"
Getting even wackier, maybe the first message will be "...ooooooooooo! woooaaaaaaaooooouaaaoooooo!! oooooooooaooooooouaaooooo!" Captain, we're receiving whale song! ;-) Or, "....are likely to be eaten by a Grue. /n 71/80hp> _"
Hell, we've been broadcasting for ~50 years now... maybe message one will just be "SHUT UP!!!"
"A witty saying proves nothing." ~Voltaire
"d'Oh!" ~Homer
When you say give or take 1k years ...
Take 1000: no radio
Give 1000: Massively improved detection and broadcasting capabilities.
The odds of all the other civilizations being even within 1k years is tiny. What SETI counts on is that we won't be able to hear the people less sophisticated than us. The people much more sophisticated than us should be capable of blaring out messages so loud they would be hard to miss (if they are interested in sending messages).
"Who is the Journal of Quantum Physics going to believe?" --Stephen Hawking
"all your base are belong to us"
What if everybody in the galaxy with radio tech is listening... and nobody's sending anything? Sort of a cosmic phone system where all the subscribers are sitting around waiting for someone to call their answering machines (we'll reply after we've listened to your message and decided whether we want to know you or not). Not much of a start for a galactic civilization, I guess... but hey, it's a dworp-eat-dworp Universe out there.

People's desire to believe they are right is much stronger than their desire to be right.
Will it probably be distinguishable from random noise?
Lets face it, we're not the only civilisation in need of compression and encryption. In fact, I would assume that aliens would be advanced enough to make our most potent compression and encryption algorithms look like 1st grade maths. I would also assume they would want to use the available communication bandwidth as efficiently as possible, so even if unencrypted, I assume they would use compression.
Now, for those of you that don't know this (very few, I'm sure), the point of compression is to reach the best possible entropy relating to the information content of the data. Or, in short, to make the resulting data as random as possible.
So what do I expect to hear from aliens?
A: White noise.
In the case of compression + encryption
A: More white noise.
Hey! That's what we're already hearing! Cool! Conclusive proof of aliens!
Another thing that bothers me: WE are not sending any 'Hello Universe!" messages into deep space (other than TV and radio), because, as I've read, it is just too expensive. In broader terms, it's a lot of hassle.
What do you think the odds are that there are a whole lot of races listening, and no-one is actually transmitting?
Whatever. A few hundred years in technological advancement means nothing in the terms of "apes" or "ants" as you infer. Technology does not affect the ability of a race to learn, conceive, or use said technology. We've come across a number of stone age civilizations on our own planet and they are not like apes compared to us. They can learn and be integrated in rather well. Japan went from a fuedal society to a technological world power through their own acheivements in a few decades. Biological matters that will require us to think of other races as either apes or ants take evolutionary changes that are factors of millions of years. Even if they have the technology to change their genetic make-up to something advanced enough to consider us "apes", they'd have the same abilty to advance us the same way should they choose.
What will matter will be cultural differences. They will encounter us, we might be unwilling to accept their culture and technology, at least in a large enough step to catch up with them. They will have the advantage of a higher technology and how they treat us may depend if they have a klingon type of civilization and enslave us or Federation and simply leave us alone. Most lilkely it will be something in between and they'll off shore factories and work to our world because we're backwards, have unexploited natural resources and work for cheap.
...may have invalidated the theory that singularities can be used to travel around the universe at will. If you go into the black hole, you're toast.
The Drake equation is a way of phrasing the question so that it's not a "SWAG" based on nothing but intuition. It teases out the variables in the equation so that you're able to think clearly about what the chances are, assessing what you think each variable might really be. Choose your values:
I'm struggling to see how your "0-5" guess approaches anything like the same level of considered thought. I can sure rig one of the Drake calculators out there to get such a result. But you don't want to even bother with that, so you dismiss anything like a real, thoughtful guess as just as haphazard as yours?
Ignorance and incuriosity are soft pillows, but only for hard-headed people...
"Fundamentalism" isn't about divine morality. It's about human authority.
What do you mean 'no other'? I've yet to be convinced there's intelligent life in the galaxy at all. Cogito ergo spud.
This article quickly assumes we're still here after the strange year of 2012. It's hard to tell what to expect.
I predict 2010 or 2011 by the latest.
And I don't believe it'll be because of SETI.

Where the air is fresh and the water clear
With lots of sun like you have here

Even if we DO hear alien broadcasts by 2020 the civilizations will most likely be hundreds if not thousands of light years away. 1) there is no way that we can currently travel those distances and in any sort of reasonable time 2) by the time we hear them their planet could already be dead and gone

... the Sigularity being transhumanism's (Vinge's?) word for the time when a man-made AI entity exceeds the intelligence of any human. As unlikely as I think THAT is, it seems more likely that the first "alien" intelligence we meet will be one we create rather than one from outer space... or from deep in the ocean or in the Earth's core or wheverever an alleged ETI thing is hanging out.
If it were inside the Earth, it would be an ITI (Infra-Terrestial Intelligence), wouldn't it?

That'd be some bas-ass lag time.
sure to get us all killed.
Everyone thought we'd all kill each other with nuclear weapons. Since it hasn't happened yet, we've been lulled into thinking we were being paranoid. We were not. Not only could we have killed ourselves with nukes, we still can.
But that's not the worst of it.
Nuclear weapons were the first class of weapons which could kill everyone on the planet. But they aren't the last, or even the worst. Nuclear weapons, as should be filtering down to all of us via the coverage of the recent events in Iraq, are difficult to construct even for nation-states with BILLIONS of dollars to throw at the problem. Also, it takes a lot of time and, as Iran, North Korea and others have found out, is relatively easy to detect.
Biological weapons, however, are a different story. The knowledge of life and death are inextricably intertwined; how can you seriously figure out how to cure disease if you don't know how it is caused? Indeed, the primary way to study curing disease is to CAUSE it in test subjects and then try to fix it. The secrets of life (and thus death) are falling rapidly before us and it turns out to be frighteningly easy for small groups or even individuals to create disease that would encircle the globe and kill literally billions.
In fact, the only thing stopping this from happening is the lack of crazies who don't mind killing billions indiscriminately and have managed to keep it together long enough to get a degree in microbiology. Over the next fifty years, the bar for being able to modify life is going to keep lowering, while the population of crazies (along with the rest of us) will be increasing.
While the prospect of nuclear holocaust is a frightening possibility, it is much easier to prevent. The bar is high enough that one may operate at the nation-state level to ensure non-proliferation and as little all-out warfare as possible. But how can you prevent a single madman from using the techology we're creating to cure disease to create one which will fell us all?
I believe that life is a natural outcome of certain conditions that are likely to have existed sometime in the past 5 billion years in millions of places in this galaxy, to say nothing of the rest of the universe. Intelligent life with the ability to create a techology sufficient to spread itself to other planets is much rarer. Part of the reason is that intelligent life is rare compared to normal life and the other part is that the techologies likely to have co-developed with a potentially starfaring culture are too easily turned against themselves.
I'm starting to think that the Amish may be on to something. Then again, not many Amish civilizations would be detectable via radio telescopes.
..."c"restrictions from the current physics knowledge notwithstanding"
Uhhhh.
If by this you mean they will break the light speed barrior, you're guessing.
If by theis you mean they COULD travel, it will STILL take 20,000 years to visit many places.
*Exactly* how do you conclude they would have already been here. The galaxy is a BIG place.
I would demand considerable intel prior to engaging in any conversations with aliens. There are several reasons reasons why RF comm isn't common place out there:
- nobody ever there
- nobody around anymore
- nobody wants to be located
Is it a rule, that there's an exception to every rule?
I'm a believer in the possibility of intelligent life on other planets but since we really don't know how far along we are to finding intelligent life, how do we know when we're going to get there?
To give you a geek analogy, it's like your downloading a file of unknown length and you finally got a byte of data from someone and you think that oh I'll be finished by 2020 because this file couldn't be more than 2 terrabytes and I'm getting 1 bit a second. Unfortunately the universe is a big place and the stream of data might never end so estimating your completion time is meaningless.

How can we expect to detect radio transmissions from another planet when we cannot even truly detect the planet itself.
Sure - we can see the wobble its host sun makes as it orbits, but do we actually have the resolving power to see it - could we even detect a tiny rock like ours, or are we still limited to the super massive gas giants?
Now, Consider the strongest signal WE could produce, how bright(radio strength) could we send a signal?
Could we send something out SO bright that it overrides the emmissions from our own sun.
Whilst I want it to work, I do not believe with current tech we will do so.
Perhaps, the aliens also come to the same conclusion, and find that the only way to light a beacon across the universe is to do something BIIIIIIIIIIIIIIIIIIIIIIIIIG.

Scenario 1: Aliens are on the same level as us, with no space travel. Having nothing better to do we chat back and forth, using the universe's slowest IM. "Hey Bill! How R U?" "My apologies Plugh, the human known to you as Bill died a few hundred years ago." Scenario 2: Aliens are savage, but have the ability of space travel. (No doubt stolen from the last morons to visit their world.) They promptly head this way for conquest/lunch. Scenario 3: Aliens are incredibly advanced, their ships arrive as soon as they get our message. Who gets to explain poverty, murder, war, child porn, etc, etc, etc to them? What, no one raises their hand? Well maybe we shouldn't draw attention to ourselves until we're ready for the consequences. Just a thought. Any other scenarios are welcome. ;)
Well, I've never heard anyone refer to Al Qaeda as "modern thinking", but there's always a first time. I agree the MP3 comment falls under the category of humour, but to be cautious regarding the unknown is simply wise. No one suggested nuking (other than you). Because an alien race's agenda would be unknown, the wisest course is to avoid hysteria on either side and approach cautiously. A phobia is an irrational fear, that's not irrational; welcoming them with open arms without any knowledge about them is.
I've held the same idea for quite a while now. Galaxies are like pools of gasoline. We are the spark. (What's the chance of an independent spark occurring elsewhere before we engulf and devour?)
But now I'm wondering about other galaxies. What happens when we take over this galaxy? Will we let all that energy go flying out into space? How long before we start encasing stars in solar panels?
Maybe the SETI people should start looking for the disappearance of stars and/or galaxies.
But then, a disappearing galaxy might be caused not only by the enveloping of their stars but also by the shadow of the robot fleet they've sent our way to start the process here.

Will we find intelligent life on Earth by 2020?
Hey, wait just a minute......we can't make "first contact" until AFTER the nuclear war, and Zefram Cochrane invents the warp drive in 2063. To do so otherwise would mess up the whole star trek timeline! Oh, what am I saying, WHAT timeline LOL..... (for those of you who take the whole star trek thing wayyyyyy to seriously, this was suppose to be a joke message).......

Maybe so, but if someone had asked me 15 years ago what kind of video games i'd be playing these days, I would have said it would involve some sort of VR/immersion.
Flying cars, personal jetpacks,etc.. Technology doesn't always develope in the ways we expect. We are a lightyear ahead in some fields (than we were 20 years ago) but not much further in others.
It seems like everynow and then we'll have a breakthrough which kick starts innovation but after awhile it crawls to a snails pace. ie, airplanes, computers.
Take airplanes for example, we've been travelling in jetpowered planes for awhile. Whats the difference now? They are a bit safer, faster, bigger and efficient. But its fundamentally the same as it was a few decades ago.
A hundred years from now i'd be surprised if we have more colonies than mars and the moon. I'd be really surprised if it would be affordable for your average middle class person to book a trip or even move to one of these colonies.
"Thanks to the remote control I have the attention span of a gerbil."
As long as all the other views are being represented I figure it's only fair to remind everyone that there is a third option; we may have already made contact, unbeknownst to the general populace.
My conclusion is that either we do happen to be the first one on the block, or that there may be a very few alien civilizations, that have chosen to be "quiet"...
Sort of like, eh?

100 years ahead does not translate to 100 years backwards.
/. example, eventually Moore's Law will run out--if nothing else, it'll hit plank-length constraints and speed limitations imposed by C.
Not on an exponential scale--but first you need to prove that we are on an exponential scale, and not merely riding the exploration of a half-dozen core principles.
At some point we will run out of basic principles to rediscover. To use a common
I'm sure that after the discovery of the sail, ocean travel and its benefits increased exponentially for a time--before finally the basic innovation ran its course, and was as fully understood as it could be. Multiple core principles doubtless build upon each other, but eventually the rate of "invention" will decrease and slow.
The Drake equation addresses the probability of ET life. Some of the values used in the equations are known, some are estimates, many are at best WAG's. I would NOT put a whole lot of confidence in any dates based on those values. Oh, but I forgot, Slashdot people are used to dealing with estimated software project dates. :-)
[Insert pithy quote here]
that's making the assumption they survive the technology they create. Humans are rapidly destroying themselves and their planet. Technology is power. The more technology, they greater the ability to destroy.
It is reasonable to assume that life on other planets probably evolved only similarily basic lines of competitivity as here on earth. And with that competitivity, perhaps alien creatures that are abberative enough to become as intelligent as we, are usually end destroying themselves through technology because of the unstability inherent in a competitive psychology model.
Maybe they're out there, but just don't usually survive the arrival of technology for very long (like us).
>Is it true, that there's an exception to every rule? Yes, except that one.

The prediction makes some sense, assuming that there ARE aliens to begin with. I personally believe that Earth is the only planet in the universe with life. I won't be at all upset, however, if I turn out to be wrong.
See this.
If "over 400 government, military, and intelligence community witnesses testifying to their direct, personal, first hand experience with UFOs, ETs, ET technology" isn't good enough for you, then start here to research our gov's own documents, and then go here and dismiss these reports with "swamp gas" or "venus" or "a flock of birds". This "we may contact other intelligent creatures someday" is a farce. They are here and have been for millenia.
Let me quote you:
The exponential nature of tech growth implies that we are like apes to a civilization even 100 years ahead of us, and like ants to one thousands or millions of years ahead of us.
"Like apes" and "like ants" is a clear indication that you were talking about intelligence. If you WERE talking about intelligence, then the encounter wouldn't be as harsh a difference as you suppose--see the problems the British had with far-less advanced natives in Africa, or the current struggles we're having in the War on Terrorism.
Read "A Mote in God's Eye" by Larry Niven for an example when it really is a good idea to instantly nuke them.
didn't mention Al Qaeda.
I totally agree that it should simply be "cautious regarding the unknown". That is proper behaviour. Avoiding hysteria is even a better thing to mention.
Yes, the MP3 thingy was humour. So was the "I for one welcome...". Though the last sentence was summing up some irrational fears. The phobia. Guess my post was a little too political, sorry.

The problem is that any signal that doesn't look like noise is wasting bandwidth. About 80% of AM broadcast (including broadcast TV, which has an AM video signal with FM audio) is "carrier", so it's easy to find those signals. Most newer systems, like spread-spectrum cell phones, not only have no carrier, but they're spread out in time, space, and code. They look like noise unless you know how to synch up to them. There's redundancy, but it's inside the coding. You need to receive a high percentage of the bits to find it.
The SETI guys mostly look for "carriers", or at least signals with a big single-frequency component. The whole sky has already been searched for signals like that, and there are no high-power carrier emitters in range. Looking harder for carriers is a dead end.
In the spirit of this one liner that I frequently hear here:"I, for one, welcome our SETI overlords"
I think the RIAA should fund SETI. After all, what about all of that music potentially being enjoyed by aliens, and yet what revenue do they have to show for it?

The exponential nature of tech growth implies that we are like apes to a civilization even 100 years ahead of us,
Many of the key results of the 20th century involve the limits of what we can do. Godel incompleteness, and the speed of light to name two big ones. There is no indication at all that any civilisation, no matter how advanced, will be able to overcome the lightspeed problem and make us look like ants.
technology to visit the entire universe at will ("c"restrictions from the current physics knowledge notwithstanding).
You want the lightspeed thing to go away, don't you? Unfortunately wanting counts for nothing, and there's not a shred of evidence for that, and plenty against. Even given nigh-infinite knowledge, physical limits are physical limits.
Many, including me, believe that within about 100 years, a civilization like our would have the technology to visit the entire universe at will
It's entirely possible that a civilisation like our will, in 100 years, have A-bombed, bio-plauged, chemically poisoned or just polluted itself back to the early stone age. Or worse, wiped itself out entirely. I'm all for progress, but dude, go easy on the prozac.

For all we know, humans might rank at the cattle level on a galactic scale. You know - really stupid and very, very tasty.
The reality is that the aliens have been here since the Roswell crash. Unfortunately, they do not want to be friends with us. Their plans for global domination: make the population lazy, fat, and stupid. Simply visiting a mall near you proves that this has been accomplished in the United States.
Once a great country strong in manufacturing, the United States has withered to a "service" based economy, full of effete, physically and mentally weak pudge-balls.
They took control of the Department of Agriculture and produced the food pyramid, a badly disguised plan for stuffing the population with carbs. They infiltrated the food industry, creating the process of partially hydrogenated oils and introducing corn syrup to promote delicious marbling of the flesh. They were almost found out when Reagan, long under the influence of the aliens from his days as an actor, made ketchup (primarily corn syrup) a vegetable for school children.
The people are sheep who believe anything that TV tells them without the hassle of critical thought, as if it were even possible with all mainstream media under the control of 3 or 4 companies collaborating with the space aliens. The leader is an idiot, completely incapable of acting without his handlers telling him what to do, even in cases of national emergency. He is incapable of genuine, natural speech, only parroting what he has been told or is written on a teleprompter.
I welcome our new, benevolent overlords. P.S. - I know a few good recipes for human.
That's why I'm always eating garlicky foods. 'Cause everyone knows that the vampiric aliens can't stand the smell of garlic. But... if they're not undead, I guess I'm screwed.
The odds of them being within a million years could be even less. We have no model for figuring the continuence of our or any other culture for a million years or any idea that if not when the age of man ends it is replaced with something LESS advanced. Who's to say that in a million years the dominant life form won't some kind of intelligent shellfish? There's no way to know but importantly there is no reason to assume that million years advanced earth dwellers resemble anything remotely close to us. There is no way to estimate how long the technological culture of Epsilon Eridani 5 is going to last either. It may have come and gone a million years ago and they took a look at earth and realized it was pre-intelligent or at best just not worth looking at.
...and will they think we're a planet of serial killers when they're asked to play Doom 6?
Will the lag time be low enough to play Doom 5?
Who's side would they be on....
Hmmm....
One thing I have thought of is that an sufficiently advanced race could have the technology to either move stars or simply igniting them as supernovas.
By doing this in patterns, a message, or atleast proof of tampering, could be created. Perhaps a subproject for Seti to work at?
I guess we all know the message we'll find though... "FP!"
His point was apparently that non-modern thinkers can also be xenophobes.
I agree it's a long shot, but what's the harm in looking?
Looking takes resources, and resources are finite. Those resources, directed in a more practical direction, might even facilitate an earlier rendezvous with ET. A simple analogy: From the dawn of time, mankind may have aspired to reach the moon. Over the centuries, we applied our limited resources in a variety of ways. In the end, technology was advanced to a point where reaching the moon was indeed very plausible through rocketry, and the trip was made. Now lets go back to the dawn of time, and lets say part of the people that contributed their resources to developing technology, the same technology that in our reality was responsible for getting us to the moon, lets say these people instead contributed their resources to a futile project to provide direct access to the moon using technology that was readily available at the time; a tower. In the end, the tower would never reach the moon, and technology would still advance to the point that rocketry would still be responsible for our lunar voyage (although probably at a relatively later date). Would there have been any harm in the long shot, the tower to the moon? Is there any harm in SETI? Perhaps if our resources were limitless, and the persuit of a project like SETI didn't potentially take away from resources for more worthwhile projects, then I might not be arguing that the harm is in fact there, and very, very real.

As I mentioned in reply to another post, you are equating 100 years forward with 100 years backward..
And as I said, you haven't given one spec of data to back up your claim that technology increases exponentially, and that this increase would cause any problems at all with peaceful or agreesive contact between us and a hypothetical alien civilization.
So many questions arise from this:
Will the babes look like from Aliens or Amazon Women on the Moon?
When can we expect the warp engine design to be completed?
Can we get a Stargate of our own after this?
Who will represent us in the Galactic Empire Senate? Not Bush, I hope.
Will rednecks keep claiming they are special for being the only ones who see the aliens and are probed by them?
Oh, well. Whatever... I just welcome our alien overlords.
Once in L.A. after a rollicking night out, I was riding my bike home with my girlfriend. It was 2 AM. We had our blinky lights on. There was absolutely no one else around on Santa Monica Blvd.
Then, it dawned on me - who the hell has blinky bike lights on at 2 AM, except uber-nerds?
Were we just blinking "beat me up, steal our bikes, we are defenseless uber-nerds? "
So, we turned them off, and felt safer riding home.
Wonder if some of our extra-terrestrial searching efforts may be viewed in a similar vein.
What, me worry?
I think, therefore I thought.
Suppose we were colonized by some brotherly (fatherly?) entity (such as via living cell deposits in the fresh ocean, which were somehow known would evolve into more complex organisms in this environment) and we are simply temporarily ignorant of our relation to "the rest of our civilization" because there is something significant about "growing up unique and without outside interference", but that at some point in the future "the news will be broken to us", along the lines of a child one day being "old enough" to learn about sex from the "elders", even though the sexual potential was actually there all along? Along those same lines, perhaps it is possible for a civilization to learn of such a relationship "prematurely".
Beam me up Scotty....there's no intelligent life here!!!
Just a thought - is there anyone on earth working through not-so-positive first contact scenarios? I know the US government sponsors groups that work out worst-case scenarios with regard to war and terrorism. Does NASA cover this kind of stuff? What would we do if we were confronted by a hostile race with technology vastly superior to ours? If we had to, are we even able to hit an object in orbit with a cluster of nukes? I don't think that it's remotely probable, just more interesting than work on a Friday afternoon.
I've been computing for SETI since it started,
and with my few home computers, and a
little help from the odd work machine now and then,
I've recently hit 12000 work units!
Also, I got a dual 2.0 G5 recently and it works faster
than all my other machines combined
(2xG3 333, G3 450,2xG4 450) on SETI (on the average)
While I think the probability is high that there is
other intelligent life out there, contacting them by
2020 seems a little optimistic!
However, if we make contact in my lifetime,
I'll be shittin' my pants with everybody else.
I was really fascinated by the news
that the data had other uses, as well.

...left to evolve alone for a while due to some as-yet-misunderstood need for uniqueness, civilization ego development, "learning everything the hard way" or some such end.
Imagine what it would have done to the "worldwide ego" if our entire history was simply a footnote within the shadow of some much greater collection of civilizations that we are actually a part of. Imagine that instead of society learning all the collective lessons it has in the past few thousand years, it was all taught to us via some high-tech method.
Perhaps we have actually been colonized, but then left alone to evolve for some reason. Until some point in the future.
In any event, I think Seti@home is ridiculous because surely, future communication is data-compressed and the best compression methods produce data that cannot easily be distinguished from random space background noise.
Wormholes may or may not be good for this, nevermind who knows what else out there we don't know about yet...
The ET's already know all about us! They will ALLOW contact when they feel we are ready for it, or we force the issue by spreading out into space. Until then-NADA!
As others have said in different ways, Fermi's Paradox makes certain big assumptions.
The main one is that an intelligent race would want to spread accross the galaxy or universe. A race capable of doing that would need to be more advanced than us. What possible reason would they have for colonizing every planet they could get their hands on? If they've mastered interstellar travel, then the odds are good that they've found a solution to overcrowding, etc... And it is pretty unlikely that they would have advanced that far and still be driven by greed and avarice.
The other big assumption is that we'd actually be able to detect them. Maybe another race has colonized the entire universe. We've just barely begun to detect planets outside our solar system. Maybe once we have a telescope powerful enough to see one of these planets we'll see it covered with cities or whatever. Maybe they've left our solar system alone to give us a chance to develop on our own.
The most likely situation, given the age of the universe, is that they are billions of years ahead of us. If that is the case, then the intelligence "gap" between us and them is about a thousand times greater than the gap between humans and bacteria. When was the last time you tried to communicate with a bacterium? When was the last time a bacterium was able to detect the fact that the entire Earth is colonized by Humans?
Believing Fermi's Paradox requires you to assume that aliens are basically very similar to Humans, but with spaceships. Not likely, except in Hollywood.
You assume we will stay in our current form in the future. Presumably the bounds of acceptable genetic engineering will widen, so humankind could diverge and expand abilities. It may also be the case that computers will become advanced enough so that personalities can be uploaded/created on computer. Given more computer power thought power would have few limitations.
To play Duke Nukem forever with our newly found friends. Still, the lag will be kind of extreme for this endevour, no? Personally, I think aliens are vaporware.

Physics is good
coseti.org promotes the optical approach to seti, which makes a great deal more sense than radio seti. Anyways, I don't plan on posting again here, so I'll quickly mention the #setiathome chan on EFnet, in case anyone wants to IRC the topic of SETI.
Bingo. Considering advances in string theory (T-duality -> large extra dimensional branes...), I'd say there's a good chance we won't even choose to exist in boring old 3+1 spacetime in 100 years. Observers that grow more complex in time form the largest subset of the mathematical ensemble, which is why what it is to exist is to be conscious observers. I've got a new paper -Statistical Metaphysics - about this stuff on my website, you should check it out.
All Abstract Structures of Objects and their Relationships exist.
I believe there is life out there, but that doesn't necessarily mean that it's possible to travel across the stars.
Maybe the speed of light is a hard limit for people (as opposed to clever physics tricks).
Maybe there are no Star Trek style "inertial dampers", that allow soft squidgy human bodies to accelerate to those speeds in any reasonable timeframe.
Maybe there's intelligent life all over, but it's so far away, for all species, that it'll never amount to anymore more than an, "oooh, isn't that interesting."
Perhaps not the romantic notions we're looking for, but one of many possibilities, perhaps.
*I feel like I should plug one of my favorite authors, Bruce Sterling, and my favorite series of stories by him, dealing with the Shapers and Machinists.
"Created in his image" doesn't necessarily means appearance. If god's a spirit creature or an intangible omnipresent omniscient omnipowerful entity, there's a pretty good chance he doesn't look like anything that a human could recognize.
"God's image" could mean temperment. Humans are capable of expressing every attitude displayed by god in the bible.
Creative Impulse - Genesis
Jealosy - No gods but me
Temper Tantrum - the Flood
Anger - 40 years in the wilderness because people complained about the food
Genocidal tendencies - The time the Israelites were told to slay every one, man woman child and all their livestock
Kindness - euthenizing Enoch because of all the wickedness
Moral Indignation - burning Sodom & Gamorrah to the ground for their sexual indiscretions (think goatse before the internet)
Testing of Loyalty - Testing Abraham to see if he'd kill his son just because he said so.
oh, wait, aliens like round numbers... i forgot.
Why would Aliens use radio waves? My guess is that they would use some ridiculous HD holographic signal which allows our 5 sense (+their 3?) to be triggered by these images.
And off on this planet somewhere there is an argument as to wether or not they should use some type of more primative means of communication. Those in charge point out that any civilization using a more primative means of communication would not be worth finding. (A planet of caddle for example).
Thinking of how old we estimate the Universe to be, smart money says we are not the most advanced speces ever.

"Who controls the past controls the future. Who controls the present controls the past." -- George Orwell
Who's to say that the aliens will communicate on the frequencies we're searching - they might even have a whole new way of communication that we've never even thought of. For us to have any chance of discovering extra-terrestrial life, the alien civilisation has to be at about the same level of technological advancement as us, and that's very unlikely.
We can't currently pick up ET signals equivalent to what Earth is broadcasting to space, even if they were coming from Alpha Centauri; they're just too weak.
This is an analog problem of signal to noise ratio, far more than anything else, so faster processing won't help a bit.
A cryogenic Allen array (to minimize thermal noise), especially in space far from Earth, or on the far side of the moon, would help a tremendous amount.
Usually discussions about SETI itself don't bring that up, because of issues of optimism and such, but it was easy to find web hits on the eseentially identical question: can ETs pick up Earth signals?
"No", says this Seti League guest editorial "ET Detection of Earth TV Unlikely" that goes into a little technical detail.
Similar comments by John Dreher, Staff Astronomer, SETI Institute, although he goes on to assume that ETs would be able to pick up weaker signals than humans are able to -- assuming implicitly that ETs will have better analog technology than we do (maybe they do, but that doesn't help us to do the same).
What about ETs actually beaming a signal at us? Maybe they do so to all nearby stars, one by one. Maybe...would we do that?
"...it has been agreed by all relevant groups that we should not be actively sending out messages to try to reach other civilisations", says another page
Ok, so we would not be so foolish as to attract undue attention from an unknown and possibly hostile galaxy, but maybe ETs will be more naive than that. Or a lot more confident (play ominous music here ;-)
So, bottom line, this is a cool topic, but are we planning to build a cryogenic Allen array in space in the next two decades?
I think we should, but any predictions really should be based largely on that one issue.
P.S. the recent lab verification of photons having orbital angular momentum, able to carry arbitrary amounts of information per photon, implies a new medium we'll need to check for ET signals. Maybe that's what all advanced civilizations use.

Hey Traa,
No need to apologize, this is a discussion board after all.
Maybe I took your post about modern intolerance a little too personally. That was my half-joke / half-serious comment about Al Qaeda. i.e. wanting to destroy those who don't look/think/believe the same. Usually I hear those comments related to how bad the U.S. is; but then there's a strange silence about terrorists. I get frustrated because there seems to be little public debate on what to do about terrorism. And that's not to say there shouldn't be intelligent debate about the Iraq war too.
No offence taken, and I hope I didn't cause any.
Peace
The Aliens figured out a long time ago how to block out SPAM and Earth has been on everyones Black List for a long time . . .
I urge all of you to watch two PBS "Nature" documentaries:
http://www.pbs.org/wnet/nature/octopus/index.html
and
http://www.pbs.org/wnet/nature/suckers/index.html
The filming shows some extraordinary intelligent behavior, whether during the courtship rituals in the shallow waters off the coast or surviving the deepest reaches of the sea. Placed inside odd shaped aqurium containers with thin tubes, octopuses would instinctively explore, sliding their into the narrowist of crevices. At a major public aquarium, an octopus actually crawled out of its container and invaded a nearby container containing crabs: Did it see the crabs and recognize them visually? The doucumentaries also show how octopuses can also change the bumpiness of their skin to disguise themselves to look like rocks, as well as change the color and reflectivity of their skin to match their surroundings.
Many species of octopuses exist in the far deepest reaches of the ocean that are bizarrely unfamiliar -- ablino species that look like "fleshy" jellyfish with two flapping "ears", or the gentle "vampire octopus" with "teeth" instead of suckers on its tentacles.
Folks, these ARE aliens. They are extremely intelligent, and some appear bizarre. But:
(1) they don't communicate verbally
(2) they don't have electronics
(3) we as a human species EAT them (or some types of them), which is pretty horrible
If we are going to search for life outside our solar system, we should always keep in mind that we have a responsibility to learn about and protect the various species of animals we already have here on Earth, and that "intelligence" demonstrates itself in a myriad of ways in different species.
Aliens are currently recieving transmitions from ages ago and have decided that we aren't advanced enough to worry about. By the time their reply comes humans will be long gone and the reply will be the only proof that we existed. These long distance relationships just don't seem to work out.

What will make me more excited is when we start developing telescopes that can optically resolve earthlike planets at reasonable intersteller distances. I have seen estimations that this type of tech is not unimagninably far away...
There are quite a few assumptions that have to be taken for granted to leap to that conclusion. For instance, in making the assertion "we are here, therefore we are the only ones", we implicitly disregard the possibility that we are being allowed to evolve [semi-] autonomously... After all, there does seem to exist some evidence that we have some anthropologists (or maybe just grad students) watching us...
All kidding aside, it seems much more likely to me that the galaxy is so teeming with life that it would evolve a complex ecology of spacefaring species. Some hostile, some not, some predatory, some not, etc... The complex pressures of such an ecology would place severe limits on the rate of expansion of any one species. Such an ecology would also evolve strong ethics of behavior, punishable in the harshest of ways - these ethics (or laws) would emerge naturally from survival pressures as species work together to fend off predatory species, handle catastrophe and whatnot. It seems quite likely that Terra is known, but the various critters around have better things to do than (and perhaps even laws against) messing with another upstart species of anthropods sitting on their heals and playing with atoms for the first time.
As for radio waves? Sure they would still be used in other civilizations. We still use the wheel and fire right? Civilizations evolve like organisms; everything that your chain of evolution made use of (up to and including the salt water that still chugs through your body in the form of plasma in your blood) is still in use in your body today.
However, it seems to me that our current utilization of EM spectrum is poor - over time I suspect two things will happen to how we use EM: (1) We will encrypt everything for a wide variety of reasons and (2) We will likely use much more complex time and frequency spanning encoding techniques to make better use of spectrum. Both of these techniques lead to the appearance of white noise (or random signals). What SETI should be looking for, besides patterned signals, is even distribution of white noise across a broad spectrum - I suspect that will be a much likelier beacon from civilizations more advanced than ours.
The reason that it can be true that 1+1 > 2 is that very peculiar nonzero value of the + operator

Re: "c", I am sure you have heard of the possibility of creating/traveling through wormholes. Again, the "c" barrier and "no way to overcome it, but the above" is all based on *current* knowledge of physics.
Wormhole shmurmhole. You do know that travelling faster than light, however you do it, is the same thing as time travel (for some observers, effects occuring before the causes), and thus has insurmountable paradoxes. That is an experimental result that has been confirmed any number of ways, and any theoretical advance would also have to account for it.
If you don't know your general relativity, go back to school, it was old physics in 1920.
I'll say it again - basing your argument on wishfull thinking is a bad idea.

If you watch too much SciFi, you might get brainwashed into thinking that aliens might possibly look like humans.
But the truth is, only the evolutionary history of earth could have produced humans. Slight changes at various points in our history could have radically altered what came to be the dominant life form and if that form was even all that bright.
Some stuff I was watching on the Science channel recently explained that it was an ice age that created selective pressure in favor of hominids who were smarter, because our ancestors had to adapt to a changing environment faster than evolution could adapt. Only the hominids who could IQ their way around the problems (ie. invent clothing) were able to survive.
Now, when it comes to aliens who evolved in an environment that is completely different from ours and with little or no possibility of us having common ancestors, you really can't expect much similarity.
Now, we do live in the same universe with the same physical laws, which means they probably use some of the same chemistry. For instance carbon seems to be a much better basis for building life forms than the alternatives. Also, liquid water is a much better environment than the alternatives.
We have to ask, for instance, if life can evolve in radically different temperature ranges. Can life evolve in liquid methane? How about molten iron? We do see some rather interesting "extremopholes" here on earth, but I suspect it's easier to adapt to an extreme environment than to evolve there in the first place. (That is, there may be life still on Mars from when it had liquid water, but it's a completely inhospitable environment for abiogenesis.)
We assume that their math will be similar. I mean, if their technology is advanced enough that they could do, say, quantum computation, and they have electrons whose spin they can manipulate, well, presumably, they would have a concept that allowed them to distinguish between one electron, and then two electrons, and then three electrons. That is to say, electrons are discrete quanta, so if you're going to deal with them, you have to be able to count them. So we can assume that an alien culture will have that. But can we really assume that? What about a world 100% covered in water where live evolved in such a way that there aren't separate organisms, but really every living thing is just a part of the same continuous organism, where everything is connected in some way. If you evolved to live in a world where you perceive everything as continous and you therefore have no concept of discrete objects, then can you count? (I agree that there are some lousy assumptions here, but go with me here.)
Much too much of our world seems fundamental to us because this is the environment we evolved in. For instance, predators had an effect on our evolution. Naturally, the aliens would have different evolutionary pressures... throughout all of the billions and billions of years in their evolution, completely different from ours. So, consider a world, for example, where metalic iron is sticking out of the ground all over the place. Think about how inhabitants would evolve to make use of this ubiquitous natural resource the way humans evolved to make use of wood and animal bones. (Or more fundamentally, how our cells evolved to make use of carbon compounds as building blocks.)
Alien life could be so different that we might not even recognize it as life. No matter what you conjecture about what alien life might be like, if/when we ever do discover it, it'll be nothing like what you expect.
Hey Jivan,
:-)
thanks for your response. Definitly no offense taken and didn't mean to cause any either
I'm with you on the terrorism discussion issues. I do discuss it with my american friends a lot (I live in the US but are from holland orriginally). I prefer to discuss it based on 'prevention' and 'defense'. How do we make people not hate us and how do we defend ourselves against people who choose to hate us anyway.
Peace indeed!
"I am sure you have heard of the possibility of creating/traveling through wormholes. "
yes, we have all watched Sci-Fi.
There were thing we couldn't do 1000 years ago, and we still can't do. Going faster then the speed of light, for instance.
The Kruger Dunning explains most post on
The Drake Equation was published long before the GHZ Theory ("Galactic Habitable Zone").
The GHZ Theory starts with the Drake Equation and greatly reduces the number of planets capable of supporting life. The GHZ takes in to account that the distribution of elements and molecular combinations is not constant throughout the galaxy. We live in a small ring shaped zone that exists a fixed distance from the center of the galaxy which not only has a vast array of molecular differentiation and comparitively low radiation but (relative to the rest of the galaxy) plentiful distribution of most elements.
While it isn't known what format life on other worlds will take -- it *is* thought that certain processes like lipid/water (or ammonic or similar) interaction would be required for a semi-permeable cell membrane structure to form.
If the Drake Equation is recalculated with the GHZ being taken into account the number of potentially life sustaining worlds drops significantly.
In my opinion SETI has long used the Drake Equation as mathematical self-justification. And conversely, by openly accepting the Drake equation's overstated likelihood of ET-life SETI would endanger its own existence.
By the way I'm a big fan of SETI -- but hiding from issues isn't the way to overcome scientific setbacks.

If you believe that human experience qualifies as evidence, then you cannot compare the comparitively meager amount of UFO "evidence" with the vast amount of "evidence" for God.
Evidence must be provable and repeatable.
UFO sightings are neither.
------ The best brain training is now totally free : )
I do not think that anyone could verbally express the amount that I hate you. Every idea that you have is hare-brained. Take this steaming pile of shit that you call a thought for instance: you advocate massive internal development of the theoretical and pie-in-the-sky pursuit of space travel of all God-forsaken things. You constantly litter slashdot with moronic limp-wristed whinging about starving and ignorant children and at the same time probably think that NASA is doing wonders for us all. You and people like you are the reason why This Nation has been accumulating massive debt since the turn of the century, and I'll give you a hint: Clintonian budget "surplus" never got us out of any hot water. God, you probably voted for George W. Bush.
Math shows that even at sublight speeds it should only take a few million years for a race to colonize a galaxy. So if they're out there, they should as next door as possible. Maybe they're waiting for us to say, "hello," first. It would imply a certain maturity on our part.
I'm beginning to think that you've never had a thought which isn't utterly vapid. Math shows? What sort of math is that, McGonigle? Perfect will, single mindeset, and 100% utilisation put into scalar form for easy manipulation with algebra? Are you completely fucking stupid? That has to be one of the dumbest things I have seen this week, and the DNC has been moving into my area for the last several days. Where do you come up with these ridiculous and worthless thought exercises? Have you lost your sex drive? Does every pseudo-intellectual try as hard as you do, McGonigle?
All the animals would live in peace and all the plants would be running scared.
Maybe the signal will be from an alien communication satelite.
I eagerly await our new alien Pr0n channels.
Science is the Real TRUTH!
April 5th, 2063. we will meet ETs then.
upon the advice of my lawyer, i have no sig at this time
You are one of two people placed apart in a large darkened silent area, wondering if there is anyone else there, what do you do?
1) Devote obscene amounts of resources to constructing ever more sensitive listening appartus?
2) Make a noise.
Duh...
That estimation would still requre that inteligent alien lifeforms exists, and that the signals we get would truly be from aliens.

actually, humans are supposed to taste eerily like pork: cannibal tribes in the Pacific called humans "long pig" ; pigs are used instead of humans in fire tests, because their flesh is so similar to ours and burns in a similar fashion/rate; some zookeepers supposedly do not feed raw pork to their charges for fear that they will take a liking to human flesh by extension.
All of this, however, is blown away by the testimony of the Uruguayan football team on whom the movie Alive! is based: "the slight browning of the flesh gave it an immeasurably better flavor, softer than beef but with much the same taste."
That settles it. We are cattle.

It's time for my usual rant... SETI isn't a guy, SETI isn't an organization, SETI isn't a project. Saying "SETI predicts we'll find ETs by 2020" is like saying "Political Science ate tuna for lunch today"
This prediction wasn't made by "SETI," it was made by a person, Seth Shostak. Seth Shostak doesn't work for "SETI," he works for an organization called the "SETI Institute." Some people at the SETI Institute do search for extraterrestrial intelligence, but I would guess that most do not. As a corellary to that, most people in the world that search for extraterrestrial intelligence professionally are not associated with the SETI institute.
Seth is also an optimist and to some extent a salesman. He's not going to get donations for the SETI institute and the Allen Telescope by saying that it's never going to happen. Therefore he uses an optimistic Drake equation that results in 50,000 communicating civilizations in the galaxy.
I, on the other hand, am more inclined to base my predictions on what we actually know, rather than optimism. My computation of the Drake equation puts an upper limit to the number of civilizations in the galaxy at 750,000. It also puts a lower limit of one civilization per 2 million galaxies. We don't have enough information to make a more specific prediction than that!

Earth will make first contact with aliens within 20 years. Eh? Aliens will make first contact with Earth within 20 years. I.E., we'll use our super-duper radio telescopes to hear a strange signal that seems like it's possibly not terrestrial in origin.

Just stop talking about this and take it on faith.
Wouldn't it be sad if our first received inter-galactic message was, "Oh! You're the planet that makes those shiny AOL CD's! -- stop sending them to us!"
Homer no function beer well without.
Oh yes, like NASA really needs another reason to spend $10 billion [...]
SETI isn't NASA. Take a wild guess why it's called the "Allen" array. Ever hear of Paul Allen? He funded it, not NASA. Where have you been? NASA hasn't been doing SETI for ages.
Oh, you mean like we did before NASA existed? Or like happened each of the numerous times that NASA's budget was sharply cut?
And what are you raving about, anyway, "no other benefits" if we did detect intelligent ET life? That's insane.
At any rate, I didn't say a word about spending tax dollars. And your raving would be naive even if I had. Go rant somewhere else.

Get a room, you two.
At some point we will run out of basic principles to rediscover.
You mean finding new applications for existing tech? Have you considered the basic principles themselves might evolve in new spheres?
At some point we will run out of basic principles to rediscover.
But even the pool of knowlegde of 'basic principles' is not static, let alone our ability to apply them. In my estimation it would be unwise to place unnecessary limits on thier growth. Science and human history seem to suggest that evolution is an eternal possibility.
I'm sure that after the discovery of the sail, ocean travel and its benefits increased exponentially for a time--before finally the basic innovation ran its course, and was as fully understood as it could be.
And then came the steam engine, nuclear power, etc...
Why place unnecessary limits on the scope of your consideration? The basic principle can be applied in multiple technological spheres -- solar sails for example. And who knows what new frontiers might be revealed if man is permitted to advance sufficiently?
Multiple core principles doubtless build upon each other, but eventually the rate of "invention" will decrease and slow.
Only if one places unnecessary limits on the capabilities of human imagination, and that is something that is outside of human control.
As the evidence suggests the contrary, it seems to me that the burden of proof is on you.
Only if one places unnecessary limits on the capabilities of human imagination, and that is something that is outside of human control.
The universe exists in spite of us, not because of us.
Our understanding of said universe has advanced at a phenominal rate lately--but it's been in leaps and bounds, not a constant or predictable curve.
I challenge you to name one basic principle that we HAVEN'T got a fair grasp on. In the 18th century this was easy--flight, the power of the sun, electricity, etc., etc. In the 20th and 21st centuries, however, we've got a fair understanding of everything we see--and barring a major oversight, we are going to slow our current pace of "technological advancement" in a century or two.
As the evidence suggests the contrary, it seems to me that the burden of proof is on you.
What evidence? The basic technology in use today is hardly different than what it was fifty years ago, unless you only count the bleeding-edge. Heck, the rate of "advancement" was fastest in the early part of the 20th century, when nationwide elecricity, electrical communication, and fission all rolled out in the space of a few decades.
The latter half of the 20th century is NOWHERE near as frentic a pace of advancement as the first half. My car, computer, telephone, house, etc. all were of a quite similar form and function in 1999 as they were in 1949, and totally different than what they would have been be in 1899.
I also believe in divine creation of humans,
So let me get this straight, you believe that we're the only civilisation in all the universe? Careful when you say that, it's a big place.
I'm not making a comparison like "London is a big place", I mean truly mind-bogglingly huge. Our galaxy has a hundred times more stars than we have human beings on this planet, and they're on average about 6 light years apart. Even if the chances of our being here are a billion to one, that gives us several hundred civilisations to work with here.
And considering that recent discoveries are showing that the liklihood of planets forming around a star are only about two to one, and one forming in the temperate zone where we live is probably at most about one thousand to one, rolling those dice a billion times is going to come up with a whole heck of a lot of life in the galaxy.
Nevermind the rest of the universe, but don't you think that it would be a spectacular waste of effort on God's part to create a billion billion galaxies each with a hundred billion planets just so we have something to look at at night? Is God really so frivolous as to indulge the entire universe with only one thinking race?
is helped out by the fact that we are so unique amoung all the species on earth.
99.99% of our DNA is precisely the same in humans as it is in elephants. Every mammal and most reptiles on this planet have two eyes, two ears, four limbs, five fingers and five toes. We all have bones made out of exactly the same material, and nervous systems that work the same way. Human beings aren't totally unique, we're just a minor variation that worked out really well. About the only animal on earth we're unique in comparison to are insects and shellfish.

If Independence Day taught us anything, it's that aliens are Mac compatible. Though sadly this means only "artistic types" will be able to talk to them.
