    This question is for all of you ET ethusiasts..... I just want to make a simple statement to get this forum going.......If the universe is or was full of intelligent civilizations ("Intelligent" is relative, Right?....Right) that have existed in distant galaxies, either now or sometime in the very distant past (circa: 1 billion years ago or so for example). Why haven't we picked up any intelligent signals yet? We should have by now I would think. Don't you????

    Keep me Posted.

    why don't they have the common courtesy to send us a christmas card? We certainly did.

    It turns out that it is more difficult to detect radio transmissions than most SETI researchers think;
    http://www.faqs.org/faqs/astronomy/faq/part6/section-12.html

    quote;
    It should be apparent then from these results that the detection of AM radio, FM radio, or TV pictures much beyond the orbit of Pluto will be extremely difficult even for an Arecibo-like 305 meter diameter radio telescope! Even a 3000 meter diameter radio telescope could not detect the "I Love Lucy" TV show (re-runs) at a distance of 0.01 Light-Years!

    Norman, isn't it possible that they simply aren't smart enough? Don't allow movies to make you stupid. Just because they are aliens doesn't mean they are technologically advanced. For all we know we are the most advanced beings in the universe and we haven't been able to do anything regarding space. If this is so how do u expect "ET" to be able to contact us if we can't contact them?

    Perhaps we already have, and don't recognize it as such. A spore would make a good message, it would travel very far without degradation, only germinate under conditions where life could occur, and the message could be an hallucinogenic chemical, that only reacts with intelligent beings.

    Wow, I've never seen it laid out in that much detail before. So what we are hoping for is 1) a very advanced society that is BLASTING copious amounts of powerfull radio waves or 2) a focused signal pointing in our direction.

    Spidergoat! I love your spore idea! It could fly through space, and eventually land on an alien world. Then it could propagate itself and begin to grow! Then one day we would find a planet of highly technologically advanced aliens whose civilization had collapsed when the spore arrived and they were all doomed to wander around in a spore-induced haze.

    Reach out and Drug someone! If you could make them addictive and only send a limited supply, we'd have aliens here faster than you could say Timothy Leary!

    If there is life on other planets in other galalxies, most likely they would be populated with some form of dinosaur...Just like earth was at one time. If we expect a reply from planets populated with dinosaurs, maybe we should wait another 250 million years until they evolve into something more similiar to us....If that's the case, that planet's going to be in trouble......

    If you can't wait that long, then leave a message.

    Why? I see no reason to come to that conclusion.

    Why is life on another planet likely to be like a dinosaur?

    You know it seems to me that there shoudl be a ton of intelligent life out there, but that's directly contradicted by SETI's (thus far) fruitless search.

    EDIT: I hadn't seen this before postage:

    "It should be apparent then from these results that the detection of AM radio, FM radio, or TV pictures much beyond the orbit of Pluto will be extremely difficult even for an Arecibo-like 305 meter diameter radio telescope! Even a 3000 meter diameter radio telescope could not detect the "I Love Lucy" TV show (re-runs) at a distance of 0.01 Light-Years!"

    Interesting. Hmmm.

    So really, no data. Well, that's frustrating eh? Nothing to go on.

    You know I have to agree with you.....There is just not that many "intelligent" signals coming from deep space these days, is there??? So, it's a pretty good bet that there isn't that much in the way of "intelligent" life out there that's interested enough to send us a few hellos or howdys....Right??? Right!!! In fact, too be honest, I'm just not sure if there is "intelligent" life down here......One of the simple reasons could be the "I Love Lucy" or the "Amos & Andy" show is probably going to turn them "off" anyway about landing on Earth, if they (the intelligent aliens) happen to pick it up (the T.V. signals) by accident (maybe) while cruisng past Pluto oneday in the not-to-distant future.....So.....

    Keep looking up anyway.....

    I'm beginning to think you don't even read what other people post.

    Spidergoat:

    According to some scientists, the best way to make contact is to send out some microbes, just as you discribed. This microbes can reproduce, sending new microbes in all directions. Unlike an em signal that decays with distance, this problem will be avoided with microbes. But unfortunately, microbes travel at a very slow speed. If we ever come across some cosmic microbe that bears evidence that it is indeed artificial, we cannot be sure the civilization that created it still exists. This is a known problem with em signals, but with microbes it is much worse.

    You didn't deny haven't read anything, so you didn't read anything right? Right! So your views are based on nothing, right? Right!

    Keep looking up, norm....!
