Experts say that for a signal to be considered interesting, the same signal must be picked up at least 2 times. There is only a 1% chance of this happening, but if an advanced plant sent a signal only 1 time, it would not be considered important. Maybe some of the Spikes on the science status page are from advanced planets that sent only 1 signal. A spike is a strong signal that is picked up.

Maybe, but about 99.9999% of the time, it's going to be something else, ie terrestrial radio or interstellar noise, or even a hoax. Only way to eliminate those is through reobservation, preferably from multiple receivers spaced widely enough to show parallax if the source is close. ____________ “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.” --- Margaret Mead

If the strong signal came from an intelligent ET society, it would contain some sign of intelligence. Either counting out the first 100 primes or the first 50 digits of pi. It would seem to me that all signals strong or weak should be scanned for this type of content. Anything non Gaussian, with repeating "Beeps" etc should be looked at and compared with a "Clutter Map" of known terrestrial sources , pulsars etc. I trust that the signal processing is much more sophisticated than what we surmize is actually happening.

Very much doubt that it would be an "interpretable" signal, more likely to be a very consistent noise type signal such as earth has been emitting for about 100 years - ever since Marconi first pounded the key... ____________ Bob Smith Member of Seti PIPPS (Pluto is a Planet Protest Society) Somewhere in the (un)known Universe?

The Science status page demonstrates why every signal isn't checked. Currently: Table # Last 24 hours Spikes 3,604,522,513 1,855,793 Gaussians 590,955,345 206,870 Pulses 1,700,282,859 1,139,935 Triplets 1,547,444,710 790,328 Workunits 1,302,786,897 621,056 Results 1,291,971,534 506,762 There are about two million spikes received daily. Today there are almost four per work unit. Gaussians are a better probability, but almost half of all work units have one. There's just too much to look at. It's computationally infeasible. The only way to pare them down is to find correlating observations of the same place showing the same result. This is exactly what NTPCKR is supposed to do. And, it was finding them when it was first being implemented, but it doesn't seem to be run nearly as much as it should be. Again, it all comes down to a lack of funding. ____________ “Never doubt that a small group of thoughtful, committed citizens can change the world; indeed, it's the only thing that ever has.” --- Margaret Mead

Do you think that some of the Spikes on the science status page are signals from Aliens?

Most probably not. They are usually earth based RFI, which Seti allows for.

i am wondering if the famous WoW signal would have been processed by one of our computer, with the applications we are presently using... what kind of graphic (screensaver ones) we would get ? and what kind of results we would get ? 30 spikes and rejected cause overflow ? ____________
