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."
Yes it does.
We should conquer and colonize another planet first, then send active SETI signals from there instead.

Has this man figured out a way to send signals faster than radio frequency or light? Surely, evidence of our noisy bickering between each other will be interpreted long before his signals anyways. And what about the satellites we have cruising away from our solar system?
I don't think what Active SETI does is really going to matter at this point in time.
Stopping people from deliberately sending signals is not going to make us invisible. We've been sending signals for decades.
There is not one iota of evidence that there exists one other intelligent form of life in the universe.
As sublimely demonstrated by the parents' post, there's certainly little evidence of intelligence on this world, why should we expect to find any elsewhere?
by the time the signals sent out will arrive anywhere of significance, the disease "humans" will have been defeated by the planet's own immune system.
the other white meat!

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. :)

This idea is a stretch. Zaitsev is more or less free to "speak" to anyone he chooses.
If you want news from today, you have to come back tomorrow.
Oh my god! I'll have to add it to my list, let's see...
1. Fatal accident while driving
2. Caught in fire at night while sleeping
3. Heart attack
4. Aliens attacking earth after sending out signals
5. Cancer
I had to bump "Terrorists attack Starbucks #528" off the list to make room

Actually, it is very dangerous. The signals have been causing a certain alien's garage door to open and close relentlessly ever since they started, making him very angry and he's up to Illudium Q-35 now.
Absence of evidence isn't evidence of absence. I agree with you that we have no evidence of other intelligent life and that anything we say about other intelligence in the universe is pure speculation. What you haven't done is demonstrate "nonexistence" which the reference to Fermi's paradox doesn't do.
We've already violated the prime directive by sending porn and rock music into space with the Voyager and Pioneer messages respectively. Should an advanced alien civilization find and decode the Pioneer golden record, their biggest worry would be to be sued by the RIAA for illegally downloading Johnny B. Goode.

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.
Oh well in that case our magic will work against them so we're fine. Magic doesn't work against extraterrestrials, that's the issue here. When dealing with aliens you can't just wave a wand or plant some beans or pull some sword out of a rock, no sir. You need to either use a gigantor gun with like twelve barrels and a 200-lb magazine that doesn't ever run out of ammo, or cybernetic implants in your body that give you superhuman strength and agility. And while we're not quite far enough on cybernetic implants and gigantor guns that non-Shaq people can even lift, magic's been around for years.

or rather, in carl sagan's "contact"?
the first visual broadcast transmissions we've sent to the stars was bloody farking hitler himself, addressing the 1936 berlin games
THAT's our announcement to the galaxy
could we have possibly done worse as a species?
we stood up, we cleared our throat, and the first utterance out of our technological mouths and we go and godwin the whole of human civilization
fark us
intellectual property law is philosophically incoherent. it is your moral duty to ignore it or sabotage it
Space is very big and it takes lots and lots of energy and resources to build a craft--even just a weapons delivery system--to cross the vast distances between stars. It would have to actually be worth it to attack us. Our planet and Solar System contain no resources that aren't readily available and easier to obtain much closer to just about any other star system.
Which probably could explain why aliens might be more pacific than us.
What I'm basically saying, is that "peace" is a prerequisite for achieving "space age",
because "space age" comes only far later after "big weapons" in the technological development,
and without "peace", a civilisation may blow it's entire planet at the "big weapons" stage, long before being able to achieve "space age".
Just look at our history :
As you said, our own worst enemy has always been ourself : the other humans against which we engage war.
Specially in recent history, we've reached the point where some population have enough warfar technology and power that they might oblitared the whole planet if weapon escalation runs out of control.
Nuclear stockpiling and M.A.D. programs are the epitome of this situation.
MAD fundamental premise is that nobody will attack because everyone dies in the process of retaliation that follows (except maybe a bunch of politician hiding into caves with lots of young pretty nubile girls, isn't it, Dr Strangelove ?)
MAD seeks to make atomic war an unaffordable option because of too high cost.
The implicit consequence is that if someone played fool anyway, we WILL all definitely stop existing.
And at the same time, we haven't even reached true space travel yet, and we're very far from being able to do it on a large scale. We can only plant a couple of flags on our moon, and send two motorized webcams to the directly neighbouring planet.
An alien race that is able to detect us AND come toward earth to meet us, must necessarily be extremely advance, far beyond the point at which we are now. Which would possibly mean also having gone through a long story of dangerous technology (military and such).
If that alien race wasn't deeply motivated to be peaceful, they'll have had a lot of opportunity of blowing themselves up with all discovery they had the time to make before achieving space exploration.
Only a race that repress its tendency to kill everything can survive technology.
Even we as human have a small tendency to try to refrain of causing too much destruction.
In antiquity, pillaging and burning down to grounds enemy cities has been standard military practice, even told in classical literature.
In the middle ages, having a lot of deaths during wars was considered pretty normal.
As history progressed more dangerous technology has become available, people start being reluctant using it. Moral value change.
MAD was a pissing context without (hopefully) any real intent to engage all those nukes.
Even if atrocities are comited during modern conflict, those are much more criticized by the public (see current opinion about Irak or the various massacres and ethnic cleansing happening under dictatorship).
Slowly we are discovering that hurting each other may not be the best procedure.
A lot of the "modern" forms of conflict have moved to much more political and commercial ground. Emerging country don't long anymore to conquest foreign land, only to capture their markets.
Thus maybe, we ourselves will be able to survive until space age without blowing ourselves up with all military technology we may invent in the process.
But probably, the first alien race that will meet us will probably be peaceful because other wise, by then, they won't exist anymore.

Radio and TV signals will not be propagated very far into space because they aren't directed there. Sending signals to other stars, OTOH, would direct the transmitted power to outer space, not to the earth surface.
. . . they'd probably have to hold a lottery to determine who would get to push the button.
I've heard that mentioned a lot, that maybe they'll see our Hitler broadcasts and immediately loathe us.
Why?
We think he was horrible, but why would we believe for an instant that an alien might think the same? Maybe some of the powers-that-be up there are scratching their chitinous chins thoughtfully, impressed that we have such men.
Dewey, what part of this looks like authorities should be involved?
People started seeing UFOs about the time they stopped seeing angels. Line noise.
At an even more basic level, even if an alien race was able to read the radio signal and construct it into an audio/video feed, would they really be able to understand it enough to form a useful opinion on what it meant? The idea of a universal translator is nice for sci-fi shows, but it doesn't seem very likely that a short speech meant for native speakers would enable someone(particularly someone with no previous knowledge of any human language)unfamiliar with the language to make any real sense of it. There just wouldn't be enough context to figure out the meanings of all those sounds. It's probably not even reasonable to expect an alien race to be able to make assumptions based on the speaker's tone and attitude like a human could.
One time I threw a brick at a duck.
Very true. But even if they did, would it sound inherently bad to someone who had no idea of our morality and values?
Hitler: We must exterminate the Jews! They are destroying our society!
Kodos: Wow. Whatever Jews are, they sure are causing that guy a lot of grief. Wonder if he gets it under control?
Since only a small fraction of news on both sides of the issue was televised, ET might not have enough context even to know that we thought it was bad (although they'd know that at least some other factions didn't like him and his plans, even if they didn't really understand all the reasons).
Dewey, what part of this looks like authorities should be involved?
Even more notably, L. Ron (schmientologist) Hubbard's "Battlefield Earth", where a Psychlo reconnaissance probe picked up one of the Voyagers (in its own way a feeble attempt at communication) and backtracked the machine's course to Earth and ... that was that. After wiping us out with an invulnerable gas drone they simply moved in and began exploiting Earth's mineral resources. Conquest is easy if genocide is on the table.
By broadcasting the way we are, we're making a couple of assumptions: a. that there are no alien civilizations out there to worry about or b. if there are, they're not actively hostile and capable of making something of it. Neither is a safe assumption. Granted, interstellar distances are a perfect defense against anyone near technological parity with us, but why would we assume that an alien civilization has advanced no further than that?
Furthermore, some people maintain the (preposterous) belief that any race that is substantially more technically advanced than us would, somehow, have to be peaceful and beneficient. However, if they followed a developmental path anything at all like ours, they got that advanced by being anything but peaceable! Where did many of the historical discontinuities in our scientific and technical knowledge come from? Why, from the tremendous R&D investment the world's militaries command in times of war. I see no reason to assume that an alien race would necessarily be any different in that regard.
Consider this: how many times in our own history has a culture been damaged or destroyed after encountering a more advanced one? Take our Native American friends, for example. The more capable society doesn't even have to be warlike either.
The higher the technology, the sharper that two-edged sword.
If we are to believe that natural systems, such as the earth really are quite common, then "prey" and "predator" relationships must exist at all levels in the Universe.
So it is logical to assume that there are technologically advanced civilizations that prey on other civilizations for resources or food.
After all, we do it in our own backyard, so why can't other civilizations?
There is nothing in the rule book that I know of that says just because a civilization has conquered space travel must not be aggressive.
We continue to advance, yet we are still very warlike.

Got Geometrodynamics? Awe, too hard to figure out? Too bad.
This is pure fallacy, although I appreciate that you used the word "likely" rather than speaking in absolutes. Generally, good education comes in peace time. Sharing of ideas comes from openness and trade with other tribes/cultures. Rockets are probably based on fireworks (and aerodynamics), which are based on so-called gunpowder -- something that was not used destructively for for many years after its creation. Radar came about in war, yes, but all of the technology leading up to it was developed in peacetime. That the first need to make the next leap came about because of war is irrelevant; the technology was there, the progress was ready to be made, and if the technique was needed, someone would have made that leap.
As someone once said, "the tradegy of war is that it uses man's best to do man's worst". War is destructive, not creative. Those involved in war often claim credit for things either through delusion, or power. That does not mean that the warlike people, warlike ideals, or even warlike circumstances are the reasons such things exist. I'm sure da vinci would've preferred to work on less lethal things, if less lethal people had held the money and power.
