How To Talk To Aliens 525

Posted by Hemos from the not-a-phone-home-joke dept.
Frederic Friedel writes: "In their efforts to talk to alien civilizations human beings are currently engaged in sending pictures based on a rectangular array of dots, arranged from left to right and top to bottom. But is this stategy sound? For instance what if the aliens do not see in pictures at all, or if they think in vector graphics rather than bitmap? On ChessBase.com grandmaster John Nunn proposes sending them a trading machine instead."

    One potential problem I think we face is that the potential aliens that we could talk to will have a wide timeframe of technological development. Some of them may be incredibly advanced and maybe already communicating with many other civilizations themselves (call this time C). So the question then becomes, why would they bother listening to us or would they even care what we are saying? On the other hand, there may be life out there, but it might be underdeveloped (call this time B) and cannot even hear us yet.

    Although I think that it is highly likely that their are other civilizations out there, I think that the number of such civilizations that we can currently contact that are between times B and C may be small.

    Right now the human race seems to think that whatever they say is worth listening too, much like stories posted by people on slashdot, in their webblogs, or this very comment. But sufficiently advanced minds aren't always interested in these things.

    So I think a better way to go about it is, what could we send to an advanced civilization that would be interesting to them? Not to us.

      That's just how I feel when reading about these efforts at communicating with alien civilisations, and recieving their signals. Just because the human race has had a tendancy to explore the unknown, doesn't mean an alien race will feel the same. For all we know, they could be well aware of our existance, but not care one bit.

          Why should they be? Perhaps their scientific advances were forced by wars? Or perhaps they were just given their knowledge from another race? It really is impossible to discuss so many hypothetical situations. The point of the matter is that they are alien. Our ways of thinking may not apply to them in the slightest.

            "[...]Or perhaps they were just given their knowledge from another race?"

            ...It has already been done, time and again, here on mother earth.
            First, the greek-latin culture founded the basis for the modern science; after that, the arabs copied and expanded modern science as we know it,, whilst western europe wallowed in the middle ages. after some time, the pendulum swung.
            The problem is, no civilization can "teach" another one scientific progress. If a culture is interested, it will try and learn whatever others have learnt, PLUS it will eventually add some original content of its own. On the other hand, a civilization that does not want to learn most probably won't.

            I always recall the story about the crab nebula. it contains a pulsar, the rotating remains of a supernova, and progressively the rotation is slowing down. it one of the basis of the discovery that you can date novas by timing the rotation of the pulsar remains. We were able to ascertain that, because we know the exact date of the explosion. records say that it could be seen clearly even by day, for days on end. Point is , these records are chinese [seds.org]. no records are available from western europe or arab sources.

    But is this stategy sound?

    No. Aliens will look at the pictures and wonder what:
    "ÿØÿà" means, when they open it in a text editor. Simply put, there is no easy way to communicate with Aliens. Here's an example of what I'm talking about:

    Imagine you're on a mountain top and you want to send a communication to someone else on another mountain top. What form of communication do you use? If you're trying to reach another human being you might be able to send smoke signals, and it would help to know what language that person speaks, or the communication won't work -- they will see the smoke but interpret it incorrectly.

    If you fire up a short wave and start sending broadcasting, the other party would only be able to listen if they have the same equipment or at least the ability to listen and understand what you're sending. So high tech is dependant on the odds that your independent civilizations went in the same direction in their research and development, which statistically is likely implausible.

    The bottom line is that we might send information into space that will provoke the wrong response, or worse -- we might cause the aliens to believe that there is a strange natural phenomena on Earth that is not worthy of scientific study, and cause them to ignore any future attempts at communication. We should be attracting aliens by producing a stable intergalactic fleet of killer robot ships. They will want to trade with us if we have heavy firepower. It's a status thing, really.

    If the aliens are evil, they will respect us. If they are peaceful, they will want to come and try to enlighten us. If we have massive intergalactic firepower, it's a win / win.

    If we are weak, the evil aliens will subjugate us into slavery and good aliens will skip us because they have more pressing matters to attend to - such as the rise of a new threat in another quadrant of space they need to try and enlighten.

    Therefore, the missile defense program would benefit Canada and the US - because of the aliens!

    Sending signals into a void won't be successful.

      Keeping other creatures captive is a sign of intelligence. I remember one SF story I read where 3 people were captured and put in basically an earth zoo. They tried everything to show the aliens they were an intelligent species but everything they tried failed. Finally, once they admitted defeat, they decided to at least make the zoo a bit like home so one of them created a basic cage and caught one of the mice in the zoo to keep as a pet. Once the aliens saw the mouse in the cage they promptly released the prisoners and opened the lines of communication.

      The moral, any idiot can makes noises (speech) or tap out prime numbers (lots of animals can count, at least subconsciously) but only an intelligent species will imprison what they consider unintelligent.

      If anyone knows the name of the short story let me know because I would love to read it again.

That's why we look for radio waves with non accounted for sequences. The aliens could be trying to send us a picture, or a string of characters, or whatever, but we probably won't ever know it.

    Now the war in my country is over with the help of Romulan soldiers, the present government of Vulcan has revoked the passport of all officers who served under the former regime and now ask star empires to expel such person at the same time freeze their account and confiscate their asset, it is on this note that I am contacting you, all I needed from you is to furnish me with your bank particulars:

    1) Account name
    2) Account number
    3) Number of tentacles
    4) Enumerated psychic powers that can be used as weapons
    5) Bank address, telephone and fax number, and # of P.O. box on Vogon homeworld.

    For you to assist me transfer these credits your private bank account, the said amount is $17.5 Million or equivalent weight in gold-pressed latinum.

    I am compensating you with 20 % of the total credits, now all my hope is banked on you and I really wants to invest this money in your planet, were their is stability of government, spontaneous mutations Borg colonization, political and economic welfare.

    Honestly I want you to believe that this transaction is real and never a joke. My late father gave me the certificate of deposit issued to him by the BANK on the date of deposit, for you to be clarify because, I do not expose my self to anybody I see, I believe that you are able to keep this transaction secret for me because this money is the hope of my life, it is important."

    Communicating with aliens.

    I use to play a game with some friend a long time ago. Basically it was about the concept of communicating with aliens. You create two teams. (And keep one or two persons as referee). Now one team had to come up with the concept of an alien race. They would line up their basic way of living and their primary way of communication. The other team should compose a message and a way of sending it to the other team. The referees would then listen to the two parties and deciding how the communication would work (or not).

    This little game is a good way to explore the issues faced by communicating into space. Sometimes the races would be underwater sea squid-type of monsters the communicated with sound waves. Other times they used tactile or chemical communication. The last is an obvious way of communicating, as most parts of our body uses this way of communication internally.

    Sometimes we would put some special requirements, like the race should have long range communication abilities or should be able to do space travel. The last requirement forced the race team to explain why and how the race would pursue the space quest.

    We always faced the core issue of how to transmit the message. It is obvious to uses certain radio frequencies. (There are some wavelengths that are fairly silent in our universe, that would be obvious to use. But check out some of our attempt to locate alien, like SETI for further references of these).

    To get their attention it would be obvious to send something out of the ordinary. We have looked fore some time into space now, and have a fairly good idea of how things should look. Now anyone interested would pickup anything that would not be familiar. They would then try to determine if it was intelligent (us?) or some new phenomenon. Sending primes would be good. But anything will really work.

    Then the issue as stated in this Slashdot bullet comes next. How to encode the message. Out group quickly found some common issues. If the race communicated with light (sight) they should fairly easy be able to decode an image. Send some basic images, square, circle etc. to define how you have encoded you image. Any intelligent species (and anyone listing to space would probably be), would fairly quickly be able to decode the image. Any race not using sight would probably never decode an image! The same goes for basically all the other weird kinds of communication we came up with. Sound (ears) indicated waves...ect. Basically the message should hold several (identical) encodings of the same message.

    But other issues arose in our discussions. Would it be communication? The answer is no. It would be a one-way message. To do communication would be stupid. Wait 50, 100 or more years to answer? So any kind of "How is the weather over there?". "Do you have a cure for cancer?" (Laugh) - would be really foolish. The message should be a one-way (but might be a long one).

    But what should we send. The most obvious (if images would be used) would be sending an image of a man and woman. (Where did I hear that before). But to any alien this would be completely without any kind of content. What would these two shapes be? The outline of a gas could in space to guide the way. (No they would not like to travel so far). They might be able to guess... this is how the aliens (us) looks like. Many images with this familiar shape. A good guess. But they would never know. Let's say there was images of cars. (I think we have a lot of that kind of images if we send thousands of images to the in order to tell about us. This familiar shape from before? Is it born from this other shape that we sometimes see it inside. Or do the biggie eat the four-pointy thing with the knob? See?

    Try to pick 10-15 images and try to guess what it is if you were an alien? No this was the second part of our two team's effort. How did they interpret the message from the human team? It's a quite funny game, but also quite serious for those who wish to communicate with aliens.

    There are many instances of so-called "convergent evolution" in nature. Perhaps due to the fact that the laws of physics are (likely) pretty much the same throughout the universe, and that the phylogeny out there is due in part to those laws (two eyes and two ears to see and hear in stereo, nose below eyes and mouth below nose in most creatures, 2 limbs on each side of the body, bilateral symmetry etc.) My conclusion is that perhaps, the way we communicate is *more likely than you think* to be similar to the way a completely independently-developing intelligent race of beings might communicate.

    The AI program would continually check its own integrity and its ability to modify itself. If these checks failed then it could self-destruct. The aliens would then have to start again with a fresh copy of the program which would, at the least, be irritating.

    Windows 98 used a similar strategy to prohibit productivity. You would be almost done with a word document and the PC would lock tight.

    1) Create an AI and email it to aliens
    2) ???
    3) Profit!

    All kidding aside, this article is lame. Starting from the premise of an AI is - how should I put this? - poop. At this point, presuming that we can create AI (computable on a Turing machine, no less) is no more plausible than finding aliens to communicate with.
