Does Active SETI Put Earth in Danger?
Ponca City, We Love You writes "There is an interesting story in Seed Magazine on active SETI — sending out signals to try to contact other civilizations in nearby star systems. Alexander Zaitsev, Chief Scientist at the Russian Academy of Sciences' Institute of Radio Engineering and Electronics, has access to one of the most powerful radio transmitters on Earth and has already sent several messages to nearby, sun-like stars. But some scientists think that Zaitsev is not only acting out of turn by independently speaking for everyone on the entire planet but believe there are possible dangers we may unleash by announcing ourselves to the unknown darkness. This ground has been explored before in countless works of science fiction most notably "The Killing Star," a 1995 novel that paints a frightening picture of interstellar civilizations exterminating their neighbors with relativistic bombardments, not from malice, but simply because it is the most logical action."
Even if aliens are out there listening, would they really care? I mean, we've all seen Independence Day and Signs and all the other movies where they do. But, when it comes right down to it, we probably aren't special enough to matter.
Aliens powerful enough to matter would probably think of us like harmless bugs or small animals: sure, they take up some space, but they aren't worth the effort.
On the other hand, if the aliens want a hyperspace bypass and Earth is in the way, we might all be screwed. :)

I think we can all agree... that if the american indians had sent out regular "message in a bottle" type items across the ocean, describing their society, level of technology, etc, the Europeans would have been much friendlier when they arrived.
Or the europeans would have showed up alot quicker and did exactly what they did. I imagine they would have brought more guns though on that first trip.
There's nothing Intelligent about Intelligent Design.
Build a partial dyson sphere around a somewhat nearby star, even just a vast network of satellites, and use them to turn the light of the star on and off to send an unmistakable binary message. Occasionally this binary message can contain the encrypted 'log' of visitors, so that we can find out about them from any vantage point in the universe (but they ostensibly can't locate us like with some directional signal, unless they can trace our 'subspace signature' somehow).
This would over time 'draw' aliens to the star while giving some protection against hostile civilizations. We should be looking for something grand like this, not some 'hydrogen times pi' nonsense.
Main problem I'm seeing with the 'Oh, no, we're all gonna be FOOD' crowd saying we should hide from any possible extraterrestrial contact is that yes, our radio signals are out there. At the current distance, the 'radio shell' is extremely weak. It's that pesky inverse square law. To get an idea, it'd be on the order of detecting a gnat's fart during a heavy metal rock concert. In New York City. From Buenos Aires.
Do I advocate Active SETI? You bet. Who knows what ET can teach us til we make contact? Of course, with our history we're liable to be declared a slum & placed offlimits til we get our heads on straight...
Understanding the scope of the problem is the first step on the path to true panic.
People started seeing UFOs about the time they stopped seeing angels. Line noise.
