Intelligent Life on Earth, SETI and the Yeti

SETI is a very high tech institute in America that focuses on what is called "Astro Biology". This may seem strange as there are no living creatures in the universe, except on earth of course. Even if there is, we haven't found any. Bit ridiculous to name a whole branch of science for something that we have zero (0) nada, niks, zip evidence for. Don't we have enough problems to throw money at here on earth than to study things that we can't see, feel, measure, or...even name? I take crypto zoology more serious, there is a chance of finding a Yeti.

Anyhow, that is a different matter. What I am interested to know is how would SETI (Search for Extra Terrestrial Intelligence) even know if they have found a "intelligence". What are they looking for? How will they tell a signal from an intelligent being from the vast ocean of radio waves created by stars, black holes and other celestial objects?

Even if they do say they have something, how would we know for sure, if you manipulate the data from a heap of sand you could probably get a pattern. How will they tell a signal from an intelligent being from the vast ocean of radio waves created by stars, black holes and other celestial objects? Cheerio

I once read that if aliens were to make contact with anything on earth it would be with whales and dolphins... because they communicate telephathically and we don't smilies/grin.gif
Great blog@!

Actually, SETI@home is brilliantly low cost, as they use normal PC's linked together to crunch the data (distributed computing). You download a simple program from the University of California, Berkeley, and then this program uses the idle time of your computer to analyse packets of data that it has received. They are only looking for distinct patterns in a specific band of radio frequencies, but it is a start. The use clever programming to sift through the data looking for five distinct signals. There is plenty of information available, take a look at http://setiathome.ssl.berkeley.edu/

I love the science that is looking at the edges of our knowledge... It is true that there may be no other life out there in the Universe, but we don't know. It may be found but be too far away for us to really be able to interract. If an alien planet were looking at the earth for signs of life, it would have to be less than 100 light years away (which isn't really very far, in galactic terms), as we have only been producing radio waves (incl TV, phones, etc) for that long.

Doolally, hate to burst your bubble, but dolphins and whales communicate with sound & vision. There is an amazing statistic somewhere where they measured a whale's sound from an enormous distance, as the whale emits a loud noise, and also positions itself so the noise is "bounced" by layers of different temperature & density of water.

No Bubble burst. When I am bored at work I go on to Reuters and read their articles. Sometimes the scientific side does look a load of hog wash but gets proven later. I just store the information till oneday I either need it or I can bring it up in nonsense conversationsmilies/wink.gif

Hey Dissol, thanks for the info. So they are looking for distinct signal or paterns to identify aliens? In other words, they are looking for patterns contianing information between all the random noise?
