SETI does, that project doesn't!! I did a how report on this, see we only have limited technology, there is still a lot we haven't been able to search, because of distance, so there might be ET's out there  |

This is from SETI!! Project Phoenix, run by the SETI Institute, is the most ambitious search for extraterrestrial intelligence ever undertaken. Since 1995, it has been scrutinizing the vicinities of nearby, Sun-like stars, hoping to pick up a signal that would tell us that we're not alone.
Project Phoenix is a direct descendent of the NASA Targeted Search that was ended by congressional action in 1993.
How is Phoenix different from other experiments? It is the only targeted search. In other words, rather than sweeping large swaths across the sky, Phoenix zeroes in on nearby stars. By restricting its attention to carefully selected targets, the 28 million channel Phoenix receiver can accumulate radio energy for minutes (rather than seconds), providing unequaled sensitivity to weak signals.
Project Phoenix also checks out all signal candidates within 20 minutes of their discovery, using a second radio telescope in Jodrell Bank, England. This is important, because the hot gas between the stars can cause signals from distant star systems to fade up and down over a few hours' time.

SETI doesn't send out signals. There have only been a few transmission sent out...see this from SETI--->SETI researchers have not been very interested in broadcasting because of the long time one has to wait for a reply. If the nearest civilization is 100 light-years away, we would have to sit around for 200 years for a reply to a deliberate broadcast. Nonetheless, a few, mostly symbolic, intentional messages have been sent. One message, transmitted in 1974 from the Arecibo Observatory, was a simple picture describing our solar system, the compounds important for life, the structure of the DNA molecule, and the form of a human being. The message was transmitted in the direction of the globular star cluster M13, about 25,000 light years away..... There are other projects, as well and none of them are aggressive.  |

Well I got that right off of the SETI FAQ page on there website, you can always email them. |

I know that is on their website. It talks about them trying to ascertain that they are receiving signals, not sending them. |

LOL. That would be the funniest thing about space since the Pepsi commercial where the Martians steal the rover's tires. We're all just sitting around waiting for others to send signals, so meanwhile we all think we're the only ones who exist. Sorry, but it sounds hilarious to me. Not that it couldn't be true, though. It's just funny.  |

No, I think it is ridiculous, too. If they are going to put so darn much into this then shouldn't they be sending something out there instead of just sitting around and waiting? |

Our technology is too primitive for ETs to respond to,so they don't bother.The radio and either wave frequencies we comprihend are limited to our range of hearing.A century or so ago Radio signals weren't known to exist to mankind and now we think we have discovered all there is to know about broadcasting signals through space.We kid ourselves.The entire spectrum of technology discovered so far on this planet is archaic and primitive and will eventually be surpassed in the near future here.I look forward to it.  |

I agree that it is primitive and I think there are far better ways to send out info to the universe but no matter the case; we need to start sending something. |

I would like to make a personal point without drawing much away from the post if I can. I always thought that there is a very curious thing about space. No matter what we definitely find out, we will be SHOCKED. What I mean is this. Let's say we find aliens who communicate to us. WOW. Shocker. Or even life forms that are still very primitive. WOW. Surprise! Now, let's say that somehow we find out that, in this unimaginably great, vast reach of space, WE are the ONLY things alive on this tiny little planet. WOW. That, I think, would be a shocking surprise. So no matter what the truth is, it is going to be too much for many people. I find that interesting. |

I think that is interesting, as well but I still would love to see it all happen. Whatever it is, I want to see it and experience it all. |

Well, there is a very good reason why SETI is not sending out broadcasts more aggressively. That reason is that ALL of the broadcasts that have ever been made and sent to ANY receiver (TV, cell phones, cb radios) have been broadcast into space. The reason for this is because these broadcasts are not shot out in one direction. They are broadcasted in all directions. Therefore, since the dawn of radio, we as humans have set up Earth as a gigantic broadcasting beacon so that if ANYONE out there were listening and wanted to reply, they could. Why then, have we only ONE signal in the HISTORY of SETI that scientists believe to be extraterrestrial in origin? Well, there could be many reasons for that. One, no one is listening. Just because we are interested in knowing if we are alone in the universe does not mean that anyone else is. Two, SETI listens for signals on the wavelength of hydrogen, the most abundant resource in the universe. Could be that SETI is gimping itself by only listening to one wavelength, but it would be too costly to listen on more wavelengths and since all of our signals travel through space on the wavelength of hydrogen we figure that hydrogen would be the most likely to get a reply on. And finally, maybe life on other planets close to us have not become technologically advanced to the point of broadcasting signals yet. There are many more arguements as to why SETI is not picking up any signals as of yet. Anyway, that is the reason why SETI is not sending out its own transmissions as aggressively as you think it should. I mean, why spend extra money on something that the entire media franchise is already doing for them?  |

I work for a satellite company and am well versed in the signals that are bring trasnmitted everywhere but I don't think that is sufficient. Those signals lose strength as they travel and just look at cellular phone signal loss in certain areas or tv/audio loss. It is way too weak. |
