The EPR one also makes the assumption that aliens know Morse code, Earth alphabets, etc.

I remember an old SF story about an interstellar confederation discovering the Pioneer plaque, being appalled and mortified that anyone would send out pornography, and annihilating our wretched, immoral, libertine civilization.

Neat, I was just talking to someone about the Pioneer message the other day. We were specifically talking about how likely it was for any given civilization to understand the concept of an arrow (the idea being that the arrow itself has all sorts of historical military baggage, but that using an asymmetrical line to represent direction might be pretty inevitable) and also about how the people in the picture are pretty obviously caucasian.

These things are all fun and games until somebody includes a sample of human blood and the next thing you know, 1/3 of the planet is spending Christmas day in their pajamas on the highest possible structure.

I took a lot of anthropology and linguistics classes in school, and how exactly to communicate intelligent information is actually a pretty tricky proposition. If I remember correctly, in "2001" the monument found on the moon was in the proportion of the first three squares.
I remember reading somewhere (NY Times?), that a good example to show to aliens would be a drawing of a triangle with the numbers 3, 4, and 5 (using tick marks) to denote the sides, thus showing that we know trig.
There are, of course, more practical propositions. For instance, how do you label a uranium dump so that someone doesn't dig it up in a billion years or so?

The message that I get from the Pioneer Plaque is that you shouldn't mess with us as we can shoot photon torpedoes out of our palms.

I really hate the phrase 'you never get a second chance to make a first impression.' Of course you get a second chance to make a first impression. just not if the person you're making it on has noticed you. And there's absolutely no reason to suppose that anyone will ever notice the Pioneer plaque. So I say, knock ourselves out.

Re. the article: It's cute, but it reads like something that got rejected by cracked.com. And it's a bit mean-spirited. It's as though she expects everyone to check with her first to verify that their attempts at communication aren't mock-worthy. (Or maybe it just means that any attempt at communication is mock-worthy.)

I always liked the Pioneer plaque. To me, it looks like a couple of peaceful naked humanoids being impaled on a citrus juicer. If we got that it would scare the piss out of us, and I've always entertained the hope that it will arrive back here sometime after we've forgotten we sent it -- and the whole planet will go to DEFCON 1.

A period of 180 years, that being the time it takes light to travel 180 lightyears? I mean, it's sort of cutesy but hardly unintelligible.

All the interceptable messages and signals we have sent have taken place in such a short period that they might as well be simultaneous, and any one is as likely to be the first as another. In space they are spread so thin that any one is as unlikely to be intercepted as another.

This is the worst message we ever intentionally sent to space. Although it does teach me a fact about the universe that I didn't know, but an advanced civilization would typically know: apparently Doritos makes salsa now.

Otherwise, I'm fond of Carl Sagan's assumption in Contact that aliens are likely to receive and return Nazi Germany's 1944 Olympic games broadcast (which wasn't made to reach aliens, it was just strong enough to reach space), if only because that means our dialog with aliens will have Godwin'd from the start.

I'll let you know. I'm going to do Logan's run next week and I'm told that I may never be able to do the Kessel run as a result.

Out of curiosity, how hard is it to send a signal that would be above the noise level by the time it reached another solar system? Would you need to lease a radio telescope for a few hours, or could a consumer satellite dish, given a strong enough signal, do it?
posted by mccarty.tim at 8:17 PM on March 7, 2011


I'm pretty sure satellite dishes and radio telescopes are for receiving, not sending.

I don't think it would be too hard, just probably in violation of FCC regulations, albeit briefly. By the standards of radio astronomy, a cell phone on the moon would produce a 'quite strong' radio signal from Earth's perspective. The strongest cell phones emit about 3 watts.

I'm pretty sure satellite dishes and radio telescopes are for receiving, not sending.

They go both ways. The Arecibo telescope was used to send the message of the same name.

Gilbert, I'd just go ahead and make the wild-assed assumption that any species capable of sending out an interplanetary probe had mastered the Pythagorean Theorem.

By sure to check out the Arecibo message (also linked by jedicus just above). That was described in the article but not pictured. It was probably my favorite of these messages as a kid.

I hate the whole "naive alien" trope articles like this bank on. Seriously? Morse code is an issue? Its at least obviously not a natural transmission. The words themselves don't matter. Understanding two dimensional representations? Err, if they can build solar system size antennas or catch Pioneer flying through their space, I'm sure they can figure out how to read illustrations.

I see this trope as linked with human vanity. We just can't or won't admit that to an advanced species we'd be as easy to figure as dogs are to us. Hivemind558 won't have too many issues with human society. We're little more than fucking and warring machines. Love and art won't confuse them and fry their circuits. They won't marvel at our philosophies and religions. We're not precious snowflakes, we're just another complex replicator.

Not to mention to an ancient and advanced society most likely we won't be their first contact. Its vain to assume so. They would probably have some experience on how this stuff works. The AI expert system that handles messages from half-crazed hairless primates would probably just yawn at us the same way we yawn when yet another exotic deep sea fish is discovered.

Has anyone ever turned the color coded message into a video game yet? I swear it looks exactly how a cheap Soviet Galaga clone should look like circa 1983.

Actually from what I understand, nearly all transmissions from Earth will be indistinguishable from the cosmic background before they pass the Oort Cloud. The only signals that will even be distinguishable at a short interstellar distance are the military D.E.W. radars.

That basically means that in order to detect our civilization the aliens would really have to be exploring our solar system already. Given how we've found that planetary systems that could harbor life (and thus are worth investigating) are more common than we thought, this makes it even more unlikely that aliens would overhear us in the infinitesimally short period of time we've been broadcasting.

Receiving TV or FM from 20 light years away would be incredibly hard but not impossible (at our technology level, if I'm reading the full article correctly) for an alien SETI program at Gliese C.

... the television signals reaching the planet would be a billion, billion, billion times smaller than the original signal generated on Earth, says Dr Maggie Aderin, a space scientist at technology firm Astrium.

"Detecting a signal like this with lots of background noise would be incredibly hard, but what they would look for is a pattern in the signals to show that they were not naturally occurring."

The Arecibo message has already returned to Earth; aliens made it into an elaborate crop circle.

The Dutil-Dumas message is quite beautiful.

No discussion of interstellar communication is complete without mentioning His Master's Voice, Stanislaw Lem's masterpiece of incomprehension.
