Beaming signals into space to find ET could potentially be risky for Earth and its inhabitants. So researchers are developing a Richter-like scale to assess the chance that extraterrestrials could detect – and potentially react to – such signals.

Decades of passively monitoring microwave frequencies have failed to find any evidence of signals from extraterrestrial civilisations. Frustrated by the long silence, some researchers want to start transmitting signals towards nearby stars with possible habitable planets in a plan called "active SETI".

whole story here.

I believe that they can detect all our signals, if they so choose it. Its not a problem. I think they refuse to respond. For whatever reason. I think signals coming from the American government or military would have a better chance of success.

From Newton to others mathematics was the biggest discovery on this planet. It allowed us to see how the Universe could be calculated by numbers and very smal numbers at that. One of Einsteins theories revolves around no less than 9 charachters to explain black holes, all that power in a few numbers and letters less than a large word..

This to me shows that to understand the Universe and to understand others within this Universe you must have a complete understanding of how Mathematcis can show you this hidden Universe and I see the entire universe having this mathematical skill so yes, they would know what our signals would be if they are at the point of where we will be in the future.

Dont forget that there are many frequencies soley used by the Military of this planet..Does Seti have acces to these frequencies??What if a signal comes with in this range of Military frequencies can it be detected by Seti? who are the only ones looking for these signals.
If Tesla and Marconi could detect signals from eslewhere then these other beings should also..

Maybe they they enjoy it as background sounds, kinda like birds to us. You listen to them, but you would not respond to the mockingbird in your backyard.

Thats right but you would be curious to what kind of bird was making that sound wouldnt you if you didnt see it??

The two post directly above mine use Human psychology to talk about what these ET's do. No one except the aliens themselves, and anything that has intelligence that has encountered them would know what the aliens would do.

As for who is putting the transmitions out there, it is scientists who work with radio telescopes or something. That is probably wrong, but I think what they showed that on the movie Contact.

It would be easier to talk to the ET's through the government rather than the radio waves though, as they probably have constant interactions with them that the public doesn't know about.

I still believe the reason for the silence is because signals can not survive the natural steller noise of space, and thus degrades to static. There is to much distance involved and too much interference.

Yes I agree!!

I also read that the signals coming off our planet would only be heard around one or two light years away if aliens were using the same type of equipment as we are.

So the only way we will hear something is if a signal was directed at us on purpose. And what`s the chances in this vast universe we would be looking at the right star at the right time or anyone is even signaling us at all.

The government knows what is going on.

Don't worry they have had contact in some way shape or form.

Stanton Friedman's challenge to SETI, read it and you will understand why SETI continues to be an on-going failure.

I always liked STANTON FRIEDMAN.
He really knows how to tell it like it is!!!

If we get a call back, I doubt anyone would be home since it would be light years later. I think the closest star system is Alpha Centauri? That's what, 4 light years away. so 8 years to get a call back.

I am reading there are some 26 stars with in 15 light years from us. So, we could be having contact by at least one planet from one of these star systems but after that its becomes way to far to have any normal forms of communication.

I'm just wondering that if there is a species between Centauri and Earth, that they have space stations set up. Sort of a port between planets. How large would they be, or would they use the moons of Saturn or other planets to set up base.

I agree with Trog, it would take a VERY long time for any sort of signal to come back to earth given that most of the signals already sent out were radio waves. Even if the code was recieved by somebody, having them decode the message would presume that they would have the same mind set as humans.

ther technology so advanced and so would there means of comiunication seti is a waste of money why serch for radio signals from an advanced alien race that most likely uses a different form of comiunication than what seti is serching for

If we can detect unknown signals from Space, I'm sure other species of life can detect ours. It's just a matter of them responding.

But what if it turns out that we are the most adavanced race in this galaxy.Or other races aren't listening yet,or don't use radio technology.

Our radio and tv signals have been travelling in every direction through space,who's to say who or what is listening..lets just hope they're friendly!

I wouldn't worry. If the signals survive any meaningful distance at all(which I doubt), by the time it gets to someone willing to respond, we will all be long gone.

[font="Georgia"][/font]Surely we are all assuming that any Alien Races use the very same method of communicating that we do? Why do we do this? Is it because we are so full of ourselves and actually believe in our own self importance? By religiously following SETI's methodology we aren't going to contact anybody.

I just want to mention that as radio and TV signals pervade they become weaker. After 40 years they will be beyond your current technological ability to detect. Given 1000 or 100,000 years... they may never be detected again.


We do have a good understanding of the range of electro-magnetic signals. We are not too pompous in that area. We have nearly all of the wavelengths save one. What we do not have is all the ways in witch signals can be used. We are primitive in it's many uses outside of communications, light bulbs and microwave overs.

it is interesting.
But the alien ones are for a long time on the earth.......
