How Do You Greet an Extraterrestrial?

The LA Times is running a story about Earth Speaks, a companion project to SETI, which focuses on how we would communicate with intelligent extraterrestrial life, should we happen to discover it. Far more effort has been devoted to searching for signals or a means to communicate than the question of what we might say once contact is established, and the folks at SETI have set up a website to gather opinions on what the best questions and statements are. "So far, the messages break down into a few distinct categories. Some people want to throw a block party to welcome the aliens to the neighborhood. Others, less trusting, would warn the aliens that we've got guns and know how to use them. Another group, possibly influenced by having seen too many movies, would have us hide under the bed until they go away. 'If we discover intelligent life beyond Earth, we should not reply — we should freeze and play dead,' wrote one contributor." What would you say first to an alien?

Re:I know

Well sonny, let me tell you bout the time the wife and I met some aliens. They landed on our farm one night and introduced themselves. Nice people. We got to talkin' and of course the conversation turned to sex. Now, the wife and I are open minded, so we thought, you know, in the name of science and interspecies understanding, we should give it a try. So the lady alien and I go off the the saucer while the male alien takes my wife to the bedroom.

Next morning, the wife and I talk about it. She says the alien had such a tiny penis, she started to laugh. Well, he says they aren't built like us. If she wants it thicker, just pull on his left ear. If she wants it longer, just pull on his right ear. So she gets it set up the way she likes and they have a great time.

"How was it for you?" she asks.

I say, "Pretty good, but that alien damn near pulled my ears off!"

Nah, if the aliens want to learn English, they just need to post on Slashdot. Someone will be correcting their mistakes before you can say Alpha Centauri.

Squids

[Geoffrey.landis]

We can't even communicate in any meaningful way with squids, which are genetically far more closely related to us than any possible extraterestrials. What in the world makes us think that it would be any easier to communicate with extraterrestrials?

Re:Squids

[Anonymous Coward]

That assumption is that for communication, sharing intelligence is more important than sharing genetics.

Re:Squids

[goombah99]

That assumption is that for communication, sharing intelligence is more important than sharing genetics.

One thing that all these discussions presume is that we would be able to quickly reach a way to communicate. More likely it would take a decade. But misunderstandings like say a the chimp biting your hand making someone angry would occur many times before that.

On the otherhand if an aliaen did show up on our doorstep then it would be one of two cases:

1) it was the first visit
2) or it was the first open visit after many many other visits.

in the first case the ship that arrived would likely be both of a technology far beyiond our own and at the same time extremely fragile it being at the limits of it's tenuous exitence after a long space journey.

So it might have some nasty weapons but probably nothing we should really fear or that we could not destroy.

Basically the vistitor would be here as our guest and at our mercy.

in the second case, it would be the visitors setting the agenda,

Re:Squids

[artor3]

Why assume that if they find us, they must have sci-fi movie technology? Isn't it more likely, that they'd find us through their equivalent of a SETI project, or perhaps by saying "Hey, that planet over there looks like it might have some water on it. Maybe there's life there."

In which case, we might find ourselves receiving a weak signal from them many years later, and perhaps an un-manned (un-aliened?) probe many years after that.

No matter who finds who, it's likely that it'll take many years just to let the other know they've been found. Distances measured in light-years suck like that.

Re:Squids

[TropicalCoder]

Well what do you expect? Maybe if we stopped eating them and showed them more respect, they might talk to us. Like, if we banned fishing them for food, and instead establish bilateral talks with them, that could be a new beginning for man-squid relations. Then perhaps we could go on to establish trade links - like - we could trade them sardines and anchovies for ink and cuttle fish bone, to begin with. From there, perhaps we could get them to represent our interests with the octopus... When you begin treating others with respect, all kinds of possibilities begin to present themselves, as Obama has demonstrated in his recent speech in Egypt.

Re:Squids

[vlm]

We could also reasonably suspect some knowledge of physics, astronomy(adjusted for their location of course) and similar knowledge

Physics gets pretty hard to discuss beyond F=ma without a common frame of technological reference and there are huge mathematical syntax issues.

Chemistry would work the best since there are so many obvious constants. ionization constant of pure water. All the orbitals of an iron atom. A benzene ring is ubiquitous. Curie temperatures. Melting and boiling points. "shelf stable" chemical propellants are pretty much constant across the universe, for a given temperature range. Permanent magnet technology. Even an old fashioned steam pressure/temp table (or other useful engineering liquids, like some hydrocarbons, or refrigerants) would be the same.

Now what would be fun would be figuring out the "new" stuff on each side. Just think of what has been developed here over the last couple decades... What is this 60 atom carbon molecule they find so entertaining? Why do they want us to stick this weird mostly rare earth ceramic in liquid nitrogen with wires hooked up to either side? WTF you claim you can polymerize fluorine? Then there's "helpful" advice, like don't accumulate too many atoms with a weight of 235 hydronium nuclei in one place or else!

Re:Squids

[h4rm0ny]

So it might have some nasty weapons but probably nothing we should really fear or that we could not destroy.

A little scientific knowledge doesn't occupy a lot of mass. For all we know, it might need nothing more than a captured human to extrapolate from, and then seed the planet from orbit with germ weapons.

But it might not need to resort to direct weapons. It would, in a knowledge-based economy, be staggeringly wealthy. And humans have demonstrated themselves woefully subject to greed and credulity. It could side with one faction on Earth and have willing allies. Or it could behave as in the film "The Man Who Fell to Earth" where the alien in disguise establishes some basic patents and proceeds to build a massive business empire from there simply through its superior intellect (I really like the scene where he is watching six televisions at once). If you want non-knowledge based wealth, it presumably has mobility within our solar system and some decent analysis tools if it got here and found us. There are whole asteroids up there which are practically great lumps of valuable minerals. It could work with us to provide that wealth and the next thing you know, hyper-rich alien again and we're right back to playing the human race against itself. But the knowlede is the thing. If the alien is smarter and more knowledgable than us, that's a powerful weapon in itself if it chooses. As the main character in Use of Weapons by Iain M. Banks remarks: "everything is a weapon."

Re:Squids

[blincoln]

Why assume that if they find us, they must have sci-fi movie technology?

Because statistically speaking, it's incredibly unlikely that an alien race would have developed technology at anything close to the same time that we did. So either they will be so far behind that they won't even have radio, or many thousands (if not millions) of years more advanced than us (technology-wise).

This is why the "warn them that we have guns and know how to use them" and "hide under the bed" options are ridiculous. Any alien race we are able to communicate with will almost certainly have the technology to easily wipe us out if they want to, as well as being able to detect the radio waves we've been throwing out into space since the early 20th century.

Imagine the humans of 1900 trying to pose a credible threat to or hide from the humans of 2009. Now imagine the same thing, but it's the Romans or Chinese or a few thousand years ago versus the humans of 2009. Then realize that even a few thousand years is nothing on cosmological scales, so even that vast gap of technology is an eyeblink compared to the differences in technology we would be likely to encounter with an alien race.

Re:Squids

[Grishnakh]

Of course, all this assumes that aliens would want to be hostile to us for some reason anyway. If a civilization is advanced enough to travel here, they're probably advanced enough to not have any good reason to be hostile. The only reason for hostility would be that they want something we have, and that could really only be the planet. But while this planet is basically a paradise to us (compared to the other planets out there that we can see), that's because we evolved on it, and are suited for living on it: it has temperatures/climates we like, it has food growing/living on it that we like, etc. As aliens would have evolved on another planet, this planet and the life on it probably wouldn't be something they value that much; it could even be poisonous to them. The only other reason they'd want this planet is for the mineral resources, but if they can travel to other star systems, it seems like it would be pretty trivial for them to get mineral resources from all kinds of other lifeless asteroids and planets instead of having to fight for this one.

Honestly, I can't imagine a decent reason why any alien visitors would be hostile to us. Some of their ways might seem hostile to some, but that would only be from insufficient communication I believe (like if they treated us as lab specimens to be experimented on for the purpose of science without attempting to communicate). I think the chances of aliens coming here to wipe us all out, like in Independence Day, are pretty much nil. If any aliens go to the effort of traveling here, they probably would be interested in either simply learning about us (without sending us all into panic), or communicating.

Re:Squids

[thasmudyan]

The only reason for hostility would be that they want something we have, and that could really only be the planet.

Two other categories come to mind: the alien equivalent of religious fanaticism and some form of paranoia causing them to consider a pre-emptive strike against us. There may be many more reasons we can't fathom just yet. However, I don't disagree with you. We're probably of little interest to anyone out there, as we and our world are likely not compatible enough in any significant way.

Re:Squids

[mruizcamauer]

In a popular sci - fi story from Argentina, "The Ethernaut", one of the guidelines used by the invading aliens was to never use a more sophisticated weapon than needed, or one that could pose a threat to themselves if we ever got a hold of it. The initial attack was a deadly snow from space, that killed 95% of people right off. The rest were to be turned into slave zombies via a control device inserted into your spine... This was a mid/70's story in the form of a comic.

Re:Squids

[Requiem18th]

Assuming there are no caps to technology, if you assume technology has some limits then as the parent says they are unlikely to have sci-fi movie technology.

For instance everything seems to indicate that FTL travel an communications are really impossible, any alien visitor is likely to "leak" their presence in the form of TV broadcasting millions of years before we can actually contact them.

Another possible cap is that civilizations inevitably destroy themselves at certain technological levels so that any alien visitor is necessarily technologically crippled in someway or otherwise they wouldn't have made it here alive, etc.

There are also limits to the amount of energy that can be extracted from matter so it's unlikely that a single ship can take control of the entire earth (an army could but as what price?).

Humans of 2009 would be eaten alive by the Romans without support from institutions of 2009 providing them with weapons, rations and medicines.

In fact the more technologically advanced you are, the more dependent in your source civilization you are, an alien invasion fleet would not only be technologically advanced, but physically huge, which then forces you to consider the economics of an alien invasion, is the planet even worth the resources necessary to reach it and knock out the natives?

Obviously the first question is...

That's assuming they're more advanced than us. But if they're more advanced then us, than in all likelyhood it wouldn't be like indians meeting europeans at all! If we're exceptionally lucky it'd be like our present day society meeting the cro-magnum.

Sir Arthur C. Clarke made a famous observation about space explorers discovering aliens. If one considers the millions of years of pre-history, and the rapid technological advancement occurring now, if you apply that to a hypothetical alien race, one can figure the probabilities of how advanced the explorers will find them. The conclusion is "we will find apes or angels, but not men."

Why? Consider the history of Planet Earth. Let the height of the Empire State building represent the 5 billion year life of Terra. The height of a one-foot ruler perched on top would represent the million years of Man's existence. The thickness of a dime will represent the ten thousand years of Man's civilization. And the thickness of a postage stamp will represent the 300 years of Man's technological civilization. An unknown portion above represents "pre-Singularity Man", the period up to the point where mankind hits the Singularity/evolves into a higher form/turns into angels. Say another dime. Above that would be another Empire State building, representing the latter 5 billion years of Terra's lifespan.

If you picked a millimeter of this tower at random, what would you most likely hit? One of the Empire State buildings, of course.

Our guns vs. theirs

[oneirophrenos]

So we've got guns. I wonder how intimidated a civilization that has the technology to traverse light-years through space would be of our bullets and bombs. If they wished to annihilate us, I wager they'd be able to do it without even giving us a chance to react. If an alien race should contact Earth, I think our best bet would be to at least assume that they have peaceful intentions.

^ What he said ^

Seriously, people. Whoever it was from TFA who suggested "we've got guns and know how to use them" as a response was clueless.

If an extraterrestrial species is remotely close to human beings technologically, then there is no way for them to reach us anymore than we can reach them. Interstellar space is a wonderfully effective buffer. If we're communicating with a neighbouring species via radio, with no chance of visitation, then we needn't worry about hostilities. Try to imagine fighting a war between North America and Australia without ships, missiles or aircraft. And that analogy vastly understates the distances involved.

If they can reach us, and we can't reach them, then threats or hostility is a non-starter. Any spacecraft capable of crossing the gulf between stars is very likely so far ahead of us that we'd be unable to scratch the finish. And any craft able to cross that distance at a significant fraction of the speed of light is, by definition, able to render this entire planet sterile by way of a RKV. Think muskets vs. nukes here.

Freeze and play dead?

Freeze and play dead? Someone really should have thought of that _before_ we started broadcasting radio and TV and a planet-wide basis. Those waves really don't stop when they hit the outer atmosphere you know... By now we should be fairly well-known in our galactic neighbourhood.

As for talking about our guns, whoever shows up here has already demonstrated massively superior technology to ours (we are not showing up on _their_ doorstep are we?) so antagonizing them might not be such a great idea either.

So yeah, by all means let's throw a party and hope it isn't us that ends up on the barbecue...

Re:Freeze and play dead?

[rastilin]

I don't think that's a given. The only two things we're lacking in order to make a slow-boat colonization ship to another planet is: 1) Hibernation technology 2) The economic dedication required to do so

Well we're also lacking the technology to build a structure that can withstand the trip and take all the stuff it needs with it. Even if we had the technology, we'd still need to design and scale up smaller models till we got to a point where we can build it. But that isn't my point, my point is that we'd be hard pressed to build a colony ship even if we dedicated the planet's whole productive and economic capacity into it. Even if we optimized it with those "keep me awake for a week" drugs and 100 hour work weeks. That means that even a low tech STL ship that comes in to Earth implies a level of mass production several orders above ours. That is a scary thing. It means that if they actually wanted to fight us, they could out produce us in terms of Armor and Planes. If they have a high level of automation, they won't even need many personnel.

Don't play dead

[Pinckney]

If we are actually noticed, the problem with the "freeze and play dead" suggestion is that it if it works, we risk convincing them that we are mostly harmless, unintelligent creatures. Earth then begins to look like a habitable, unoccupied planet ripe for colonizing.

While a display of martial might would serve to make the earth look less available, it also risks making us appear savage and again, unintelligent. It might make them feel justified in subjugating us and colonizing earth.

Safest is probably a policy of partial isolation. We should greet others firmly, while revealing little of our own cultures and history. Be respectful, and allow visitors to see a strictly controlled show. Given time, this can be relaxed. If they do seem interested in colonization, prepare for war. Demand commitments to peace and respect for our territory that, if broken deliberately, will give us moral high-ground in counterattacking. But if this should occur, act quickly to establish laws of war--display an aura of civility and discipline. Conversely, if they are interested in an exchange of knowledge, be open and willing--say nothing of atrocities and wars, and let the borders be opened slowly. Control their perception of us, so that we may appear to be a mixture of cultures that they could ally themselves with, rather than merely subjugate.

What if they were to arrive in our solar system and not care about us? I mean, what if they didn't care about lifeforms? It's a huge assumption that they are looking for others like them. That's a drive that seems to be uniquely human. As far as I know, no animal on earth goes around comparing surrounding species to themselves. I use the earth animal example because we have no other species to compare in the vicinity of our solar system. But back to the point, What if they arrive and simply ignore us?

It'll be the one thing we have in common, no matter what. However they conceptualize it, unless our first contact is some kind of space manatee that communicates in radio waves, whatever we make contact with will have to have developed transmission/reception capability.

Re:It really all depends on resources

[RsG]

Wandering slightly offtopic...

What would an alien civilization able to travel to earth consider a "resource"?

For our purposes, we'd count fossil fuels, electricity, metals, arable land, industrial and commercial infrastructure, livestock, water, building materials, manufactured items, people... All things which are finite and useful.

If a species has the tech to cross a few dozen light years, they won't need some of the above. Water, for example, is easy to come by even in our own star system. Electrical generating capacity would be far in advance of our own, given the amount of energy needed to move a spacecraft over such distances. Fossil fuels and uranium would very likely be useless to a species far ahead of us technologically.

On the other hand, things we don't consider to be resources might be valuable to aliens. For example, we don't yet need He3 for anything, but we might want it some day as fuel. There are likely isotopes of elements we don't yet know the uses for, but an alien might.

The point I'm getting at is that we don't know what an alien civilization considers a "resource", or what scarcity they'd have.

However, I strongly suspect that there's no profit in travelling interstellar distances to get resources. The energy requirements for such a trip are too large; that same technology could almost certainly be put to use to acquire or synthesize resources much more easily.

There can be different kinds of intelligence

[sznupi]

But this assumption, that intelligence should be enough, relies on another - that those will be similar kinds of intelligence. Which might not be true.

Look at the example with squid. Is it intelligent? Definitely. Does it help us humans in communicating with it? Not really.

Notice that I've said "us humans". The burden of finding a viable channel for communication will almost certainly lie on the more intelligent species - simply because its modes of reasoning are totally out of grasp for "lesser" one. In case of squidshumans we, as a "higher" species, didn't really manage to figure out ways of communication. And it works for vast majority of species on Earth, except those which are very simple or those which are very similar to us (and it's still far from great in this case). And no, domesticated animals don't count - we bred proper responses into them.

The intelligence we might get into contact with will be almost certainly quite different from ours - not necessarilly because of different modes of operation (hive mind for example), but also because it, most probably, had a different timescale to evolve, refine itself.

Overall, it is likely it will be more intelligent than us. And somehow I doubt it will be very close to us, diminishing even further the chance of "close enough to find common ground". At the same time we're already quite advanced, so not exactly falling into "primitive enough".

PS. As a personal sidenote: I think that, eventually, intelligence of our type, one that is well on its way to harness power over genes, is quite short, quite transitory stage towards intelligence that is fully aware, harnesses and embraces...memes. How it would think then? Here's the point - I am unable to comprehend. But we would look to it similarly like animals look to us - totally under influence of genes, not even realising next step.

I keep seeing people posting about how much more advanced than us a species would have to be to reach earth. I simply don't see why thats true. To my knowledge we have at least general knowledge of every major technology we would need to travel between stars, and thats with NASA never having had a budget over about $34B 2007 dollars, and currently closer to half of that. If we spent less time and money on killing each other and bailing each other out, and maybe cared about something other than our own social problems, there's no reason we couldn't have people on other planets as we speak.

Consider this:
For about $135B 2005 dollars we effectively went from flying propeller planes to repeatedly placing men on the moon.
Since 2001 we have spent about $865B in Iraq and Afghanistan.
Since Fall of 2008 we have committed about $12.2 Trillion Dollars to "Economic Recovery" plans


The barrier between us and the stars is not some insurmountable technology one, its a matter of money and willpower. The only hope I see is that private interests (including SpaceX and other companies) will pursue these technologies (considering that hundreds of companies have higher revenue than NASA) otherwise I'm afraid we may never get off this miserable rock before we kill ourselves off. You wouldn't bet the uptime of a moderately important website on a single webserver, yet we continue to bet the survival of our species on a single rock floating in space.

Dear Friends,

I am Prince Fayad Musa H. Bolkiah, the eldest son of Prince Jefri Bolkiah, former Finance Minister of Earth, the tiny fuel-rich planet on the outer realms.

Due to problems with a trading guild I was advised to evacuate my immediate family outside the sultanate to avoid further prosecution from them. Before I could do that I was placed under house arrest.

Before my Incaseration, I went ahead to dispatch large sum of fuel with the assistance of friend in a galaxy far away. The fuel has now been deposited as valuables into different private security and trust company for safe keeping.

In order to get the fuel I will need large quantities of the following chemical products, the mineral Be3Al2(SiO3)6,) and the chemical lement with atomic number of 79, details about this follow.

For your assistance i will compensate you with 25% of the total fuel and another 5% shall be set aside to defray any expenses that may arise.

Please I count on your absolute confidentiality, transparency and trust while looking forward to your prompt response towards a swift conclusion of this business transaction

Closest Star is 3,900 years away

[Anonymous Coward]

The barrier between us and the stars is not some insurmountable technology one, its a matter of money and willpower.

You sir, are confused.

The fastest man-made item http://www.aerospaceweb.org/question/spacecraft/q0109c.shtml reached 150,000 mph (41.67 mi/sec). Voyager 1, launched in 1977, is going only 38,500 mph as it leaves our solar system. The closest star to our solar system is about 4 light years away (5,800,000,000,000,000 miles away).

That works out to about 3,941 years to travel there at 150,000 mi/hr.

We definitely do not have the technology to accomplish or even begin that goal. We'd need a multi-generational ship, capable of growing food without sunlight. It would need to survive longer than any culture or nation has by far.

So perhaps you understand why we aren't planning to visit other stars at all now?
