| Personal background |
|---|
I am an electronics engineer.
I live and work in the island of Crete, Greece as a Radio engineer and a Computer technician.
My hobbies include studying artificial satellite orbits and receiving signals from their beacon transmitters, Writing articles in online satellite and space specialized newspapers and desinging ultra low noise, narrow bandwidth equipment for use in amateur radio repeaters.

"If you seed a huge field, you cannot expect just one seed to grow".
Same rule applies to universe as well. whether we look at it literally or mathematically, there is a severe chance that intelligence exists in other solar systems, and I think we shoudn't be suprised to find (and that's what SETI@home community works on this very moment), that we are not alone at all.
I believe that we should look in an order by proximity, because signals tend to decrease their power on the square root of distance, so it seems logical that it is really easier to find a clear signal on nearby solar systems, rather than on distant.
A beacon should not be transmitted for various reasons. Security being the most important. It is true that the composition and the climate of Earth could be rare, therefore an extraterrestrial race could find it quite easier to hear for beacons which would mean Intelligence which in turn would mean a planet capable of holding it, rather than searching in the vast "ocean" of billions of stars for that planet.
A singal from another civilisation in the form we expect it to be would mean an attempt for communication the way we want it to be, and responding to such a signal would be quite more reasonable than using a beacon ourselves.
That of course rises more issues.
It would mean that the others could be trying avoiding trouble as well..and also mean that we probably shouldn't be looking for beacons but for other signs of technical advance.
SETI@home includes that in the search, as it looks for triplets (that could be used for basic signalling and data transfer, and radar signals(radars are quite effective in the scanned frequency, they also use high power which is easier to receive in such distance, and surely would be used by an advanced civilisation) and wide gaussians, that could be carrying information.
SETI@home seems able to pop up with interesting results, so I support it by having it up all the time, even right now, as I write my thoughts down.
A triplet popped up, who knows.. |
