Earth 'noise' could attract alien invaders

03 May 2008
From New Scientist Print Edition.

No matter how quiet we try to be now it's too late to prevent alien invaders. So says Alexander Zaitsev of the Institute of Radio Engineering and Electronics in Moscow, Russia, who points the finger at astronomers.

For 40 years, astronomers have fired microwaves off objects to chart near-Earth space and track the movement of close asteroids - and these signals are traceable back to us. By comparison, Zaitsev says, dedicated transmissions - often described as "shouting into an unknown jungle" - are a mere whisper. He calculates the astronomy signals have filled an area of the sky 2000 times greater than dedicated broadcasts have managed to date (www.arxiv.org/0804.2754).

You’re welcome.

Even who we consider the brightest minds can never lay better odds than 50/50 on any scenario. Heck, supposedly the dolphins are thinkers and communicators, and we know nothing of their worldview, and we certainly share more DNA with them than with something from another solar system.

The guy’s a moron. What are the chances that a civilization lasting long enough to develop faster-than-light interstellar travel would still be violent enough to want to conquer another planet?

Look at the history of humans. In every instance in which a technologically superior civilization encountered a less superior one, the primitives were conquered or eliminated.

Spoken like a true paranoid Russian. Of course, just because you’re paranoid doesn’t mean they aren’t out to get you.

[UCANSEE2]

Even in our own solar system.

Speaking of Space Invaders - where's Tom Cruise?

Don’t worry, If intelligent life ever comes to Earth we will know it by their laughter.

[TightyRighty]

Meanwhile in another part of the galaxy other life forms are saying “Be quiet, or we’ll attract earthlings!”

[boomop1]

OK Ned.

[mowowie]

The way i see it is if they can hear us we should be able to hear them.
also they would have to be within 50 light years away.
I’m curious as to how many stars are within that distance.

[Psycho_Bunny]

No, it’s based on life as we understand it. Not human beings.

[Psycho_Bunny]

You’re forgetting the technology aspect.

[Continental Soldier]

Maybe they live for violence and conquest. ;)

Nah, Sons of the Pioneers...

[Hot Tabasco]

to want to conquer another planet?

Because they're sick of tofu and want real beef.........

[JoJo Gunn]

No, it’s based on life as we understand it.

And that's the point - it's what we understand.

[Leftism is Mentally Deranged]

The signals will be extremely weak when they reach the nearest star. How will the aliens know how to distinguish among the many broadcasts that are made on the exact same frequency?
If they ever succeed in deciphering the Montel Williams show they will blast us into atoms for sure.

Why does the giant robot wear underpants?

I have another question. What are the best, ie most serious scientific websites dealing with the UFO phenomenom out there?
