Radio waves are so 20th century. Real advanced aliens don't even use radio waves. All the SETI equipment on the Earth won't even be able to detect advanced aliens.

Harvard is doing some "Optical SETI" work -- looking for things like nanosecond pulses that do not occur naturally in the optical/visible light bands.

I think a lot of it comes down to time. If we keep our civilization going and keep listening, sending out probes, building better telescopes, etc for long enough (100 years? 1000 years? 1,000,000 years? 100,000,000 years?) I think we have a good shot at finding something. Imagine if we kept our civilization going for a billion years -- surely at that point, if we are listening the whole time, the odds are in our favor. If we blow ourselves up 3 years from now, however....

@mikef823 what about radar?

[MsH1h1h1h1]

SETI will never work because:

1- radio signals from other solar systems arrives here completely blured

2- radio waves were only used by humans because we are too much stupid to use a much more efficient way

Anyone truly open minded about looking for ETs would investigate UFOs here on Earth and the obvious cover-up that's been going on for a long time. (That's no conspiracy theory, that's a fact.) People that say 'ETs couldn't get to Earth because of the distance' are assuming that no ET race could possibly have a greater understanding of science and space travel than we do, a narrow minded and staggeringly arrogant theory. Some ET races could be millions of years ahead - imagine what they'd know.

WHat a total waste of money

seti have searched just a gold fish bowl in our galaxy compared to all the oceans of planet earth just a stones throw in comparison 0.0000000000000000000000000000­0000000001% of our total galaxy if there is anything anyone else out there we have a long way to go, i doubt in our life times we will be any closer to finding out that earth is very special, not a freak of nature just quite rare, maybe our childrens children will find the answers.

I found a triplet (three signals evenly spaced) using SETI@home for a day on BOINC, each one was exactly 10.00x stronger than the background noise and the distance between the signals was 1.314 (reverse 1.3 and 14 and you get 3.141 = the first four digits of pi) I think the search is over...

[mikef823]

if there really are aliens do you think they are going to use this primative crap..... NOOO.thats why we will never know because they dont use fm radio.

[opforfmj]

@grogtgs If a civilization of intelligent beings would want to contact us, it would more than likely use a frequency band or a range of frequencies of radio waves, it doesn't just send out a microwave emission, there's also radiation, thermal, and infrared. So all of this combined, is searching the skies for signs of life

[VertigaDesignMEDIA]

why search for life, when you can recreate the entire universe inside a computer.

base it off proven algorythms and you have a dupliction of the universe inside a computer.

immerse yourself in this universe and explore it.

species all over the world are doing this because they are unable to explore the real universe physically. they have given up.

mankinds truly progressive role, is to successfully experience conciousness externally, and permanently so they can leave there original body forever.
