Can you tell me why Near-Time Persistency Checker is rarely updated with new canditate signals? Is it so difficult to find something interesting, or perhaps there are not any civilizations using radio in 1000 ly distance?

Hi patronangel,
The Near-Time Persistency Checker (NTPCkr) is still under construction,its not finished yet. The SETI@home project scientists will be working hard to improve it over the coming year. But its a massive amount of data, 10 years worth, so it will take time to get it working properly.

John.

So How about the results we send you back? How do you evaluate more than 12 million results you receive every day? And What exactly you are searching for? I mean I f there are 1 million civilizations or so, in he Galaxy, SETI should have detected them after 50 years of searching.

Maybe it's not as easy as we think.

At any rate, SETI@Home has only been searching for 10 years. Other SETI projects have been going longer.

The first SETI attempt was Project Ozma at 1960. The main question remains however: Where are everybody? Have you ever considered the possibility that The other civilizations Do not Use Technology based on electromagnetic waves, because their physiology and their culture are very much different than ours, or simply because the natural sources of the environment they evolved, favored the developmennt of technology wich is not based on radio waves.
Also why are they searching only at 1420 Hz? They are rejecting countless frequencies just by assuming that Extraterestrials are broadcasting at the hydrogen frequency? Why they should do such a thing?

Cash and some best guesses that they are intentionally signaling.

It costs more money to look at more frequencies. Money is limited.

As to the frequency it is an interesting frequency to astronomers, and one that doesn't have a lot of natural interference, so the thinking goes someone not necessarily looking for a SETI might stumble upon the signal anyway if you were the type that wanted to be found.

Another question I have, is why they scanning again and again Nothern Hemisphere?
There are so many stars at the southern hemispere, that they should try to make an aggrement with Parks Observatory Australia to get some data from there. This also would help end the rumors about Zeta Reticuli once and for all.

Parks is a 64 meter dish, Arecibo is a 305 meter dish. Signal at Arecibo is 298 times stronger.

All right then, but It seems that is essential that they must find a way to collect data from southern hemispere.

patronangel,
Think of it like this;
Mankind has been studying the stars in the sky for over 2000 years, so up until 15 years ago, how come nobody ever spotted a planet???
Answer - Because it took hundreds of years of astronomers studying the stars to develop telescope technology capable of detecting planets around other stars!! In the last 15 years, we have found over 400 planets, and the Kepler telescope should open the floodgate in the next year or two.

So apply that theory to the search for intelligent life! We have only just scratched the surface when it comes to searching. Only time and massive amounts of money to advance the technology will end in success. Currently SETI searches have very little funding. SETI@home tries its best to handle as much data as it can, but its difficult with so little funding.

John.

Well to be honest I would like humanity to detect a star (for example Epsilon Bo├Âtis) with civilization during my lifetime, and see the changes that this will bring to our world.
I also would like to be sure that the results I send back to SETI are properly evaluating and that my efforts have some meaning.

One must understand and contrast the differences between one's own aggressive interest with finding E.T.I. over the slow and methodical approach science uses to verify results and data.

I think we all would very much like to discover an existence other than our own in our life times, but we must set aside our urges for instance gratification that is so prevalent in our society and be patient with our approach.

Wise words indeed, Jedi Master OzzFan :)

Sometimes I think we are alone in the universe, and sometimes I think we are not. In either case the idea is quite staggering.
