Interesting comments, but, I have a slightly different perspective. Indeed, much is relavent, if the endeavor is publicly funded, ie, public input into the consumption of public resources. SETI is for the most part privately funded, and, the majority comes from a single donor. Therefore, the question that comes to my mind.

Nobody is breaking any laws, so, what part of 'free country' is unclear ?

Exactly, my gun weilding redneck drunken idiot neighbors or the cell-phone distracted driver on the highyway are much more an imminent threat to me, and they are free to do things that may bring me harm. The "made-up" (and let's face it, it is made up, there is no data to support any intelligent life out there yet) possiblity of attracting bad things from out in the cosmos doesn't scare me one bit.

Please guys, maintain perspective.

Any signal we send out will travel at the speed of light. It'll be hundreds of years before it encompasses more than a few systems.

Our Military radar has been sending out powerful radio waves for decades that are readily identifiable as artificially created.

It is also possible that other civilizations in the Universe are still in the various stages of evolution and perhaps we are the most advanced race in the Universe.

TV and radio waves most likely radiate out into space for decades... :o

if advanced civilizations exist, the how come we haven't "picked up" any of their radio/tv shows?

If there are advanced civilizations not of this planet, earth, they could be WAY more advanced than us minor earthlings and have better, more sophisticated, faster communications than "radio/tv" and probably something that we haven't even discovered yet. :foreheadslap: Heck! They might even know that we are here and see us as so backwards as to disregard us completely. :bawling:

That question was asked before when our radiation into the radio & TV spectrum was increasing exponentially for decades.

Earth was getting brighter and brighter in the radio spectrum. But now, we are getting quieter and quieter as broadcasting turns to fiber optic distribution.

Therefore more advanced civilizations may only broadcast 'loudly' for a few short decades. Add to that the extreme attenuation of any radio broadcast signal and the fact we have not detected anyone yet is not surprising.

In fact, assuming all the closest solar systems to us had comparable tech , we would not be able to detect their general radio broadcasts unless they sent a tight beam broadcast directly at us.

But then again, nobody us exactly sure where episodes of Jerry springer came from.

Why do we think that "advanced" alien civilizations know of us but continue to ignore us because we are backwards in terms of technology, science and evolution? Why do we think that faced with the same type of situation, we would ignore backward civilizations and move on? Have we ever done it? I mean in human history, have we ignored and moved on things that we find or discover? If we find "Dinosaurs" on another planet, would we just whizz past, merely giving it a yawning cursory glance? I am sure, if Curiosity discovers microbes on Mars, the world would be ablaze with excitement and hope. We will not ignore the microbes and move on, instead we will study them and try to find their origin and evolution. Same is the case with life on other (exo)planets. No matter how minuscule, how ordinary, how simple the life is, I do NOT think we are going to ignore it. Scientists will be more than curious to find out about how life evolved on different planets, during different times and under different circumstances in the history of the Universe. We communicate today using means at the speed of light with one another, yet we also communicate with remote tribes of human race who have literally no communication with the outside world. We just do not ignore them and move on or do we?

Having said that, I think at least in our part of the Galaxy, we might be the (and only) form of advanced life.

Earths 'brightness' as an artificial source of radio waves is only a sphere about 70 light years in diameter. Not very large in the overall scheme of things.

Maybe we are still just a needle in a haystack.

Could also be that something akin to wormholes are quite common in the Universe around solar systems and aliens use them like a Federal highway system. But Earth's Sol might lack this structure marooning us in isolation until we make that first interstellar crossing.

No, we don't move on until we've eaten it, caged it, or killed it.

Not exactly, but close...

Contact attempts were made, were resisted, and the eventual decision was to leave these people alone. I think that may be unprecedented in human history, until now.

The answer is, probably "yes". Study the Viking mission and all the follow-up investigations.

Using the inverse square law of 1/R^2, would any signal be detectable at the receivers vantage point? R is gonna get pretty big when we're considering the universe, and it would probably be swamped by other sources at the receiver's end. I guess they figured that out though.

Just a short SETI related story: Back in the '50's I remember seeing a movie where they wanted to transmit a signal to search for alien life, but didn't know what to send. One of the scientists sons came in the room eating a piece of pie. Out of frustration, the scientists asked the boy what they should transmit and he replied "pi" but the scientist thought he said "pie." There was a eureka moment when the scientists saw the universal relationship of the circumference of a circle to it's diameter, and that would be recognizable as an indicator of intelligent life. That struck me even that long ago.

Now, if the aliens bring good pie, then I am satisfied with being conquered and/or enslaved. I am a sucker for a good key lime pie. :)

I doubt aliens would enslave mankind.

Slavery always dies out when it becomes more expensive to house, feed, cloth and maintain a slave over buying a machine to do the same task.

Slavery only makes sense when human power is cheaper than hav'n some machine do'ing that for you......

I imagine that if an alien race could zip around the galaxy and wanted the resources located within our gravity well...they would just use monstrous harvesting machines and view humans as a more or less nuisance infestation that they may or may not tolerate.
