Scientists engaged in the search for extraterrestrial intelligence (SETI) work under the assumption that there is, in fact, intelligent life out there to be found. A new analysis may crush their optimism.

To calculate the likelihood that they'll make radio contact with extraterrestrials, SETI scientists use what's known as the Drake Equation. Formulated in the 1960s by Frank Drake of the SETI Institute in California, it approximates the number of radio-transmitting civilizations in our galaxy at any one time by multiplying a string of factors: the number of stars, the fraction that have planets, the fraction of those that are habitable, the probability of life arising on such planets, its likelihood of becoming intelligent and so on. [10 Alien Encounters Debunked]

The values of almost all these factors are highly speculative. Nonetheless, Drake and others have plugged in their best guesses, and estimate that there are about 10,000 tech-savvy civilizations in the galaxy currently sending signals our way a number that has led some scientists to predict that we'll detect alien signals within two decades.

Drake's formula was pretty primitive, and probably can't be improved upon anytime soon.

Moving on...

I like to go out on the deck at night - as I did a little while ago - and look up at the stars. We don't have quite the view here in the Ozarks that we did when we lived in the mountains up above Denver, but probably better than most.

I marvel at the sky and all the billions upon billions upon billions of stars and galaxies that I can see - even without a telescope - and think that there has to be life out there. Intelligent civilizations? Gotta be. Will we ever contact them or they contact us? Not likely........

If they want to remain intelligent they are better of staying away until we have all the lib's reeducated!:cool:

The jury is still out for me too. I'm like you and just enjoy the amateur star gazing.

as Thomas Carlyle said "A sad spectacle. If they be inhabited, what a scope for misery and folly. If they be not inhabited, what a waste of space."

Of course we're alone, at least functionally. We only got here a few hundred thousand years ago, and didn't keep records until the last 500 years.

Universe, on the other hand is 13 billion years old. The party's been over for some life forms for eons'; others are yet to achieve self awareness.

uh...we've kept records much longer than 500 years

:)Who has?

Some people have. Some not.....The Space Guys could have landed and set up shop in Montana 500 years ago and we wouldn't know. Just be a rumor people talk about. A myth.

500. 1000. 2000. What's the difference? As far as the universe goes, it's insignificant.

If they looked like us, they could have blended in. Just like in Escape To Witch Mountain!


I like to think there are aliens out there like some of the freakier ones in the original Star Trek series. Or like Q from TNG. He was fun.

if they are picking up our television broadcasts they will probably avoid us at all costs

They do seem to avoid us, except for the occasional anal probe.

If water existed on Mars billions of years ago, yes...but they're gone now...
