On Monday (February 4, 7 pm EST) NASA's Deep Space Network (DSN) sent a transmission toward the North Star, Polaris. The transmission sent was the song "Across the Universe" by the Beatles intended for any sufficiently advanced extra terrestrial life to listen to. Although this is a nice gesture and may nurture Beatles fans beyond [...]

Although this is a nice gesture and may nurture Beatles fans beyond our solar system, some scientists have expressed concerns for advertising our planet's location to the universe, just in case the aliens listening in aren't that friendly after all…

If there are any advanced alien beings out there however, they are keeping very quiet. The purpose of the "Sound of Silence" meeting is to discuss why the SETI project has, thus far, not found anything compelling to suggest there are any life forms transmitting their presence to the universe.Obviously, they're all secretly sneaking up on us right this moment! :)

I read a great sci-fi book, it was probably "The Forge of God" by Greg Bear, that suggested there were two kinds of intelligent life in the galaxy - sheep and wolves. The sheep, if they were smart, stayed silent. Those who didn't attracted the wolves.

Granted, we put out enough general noise that it probably does not matter, but I lean slightly in the direction that we should be minimizing our output, not expanding it.

No info about the characteristics of the Beatles song transmission [frequency, bandwidth, power]. I presume it won´t go further than 100 LY.

The massive Cold-War radar early warning systems we set up in the late '50s can already be seen out to 40 light-years.

Maybe sending out some music will make us look a little more evolved (at least until the ETs start picking up gangsta rap....)

Not to worry. Aliens that could & would cause us harm would be able to detect us and destroy us before we ever knew about it. Our best hope is that they will await the denouement of the Britney Spears Saga.

No. Next question.
