NASA Scientists gather in Santa Clara to ponder life beyond Earth (SETIcon)
Mercury News ^ | 6/23/12 | Lisa M. Krieger

We may not be alone.

But our cosmic companions might be moist creatures in watery worlds -- lacking, of course, E.T.'s impulse, or ability, to phone home.

The growing evidence of wet planets -- and its implications in our search for extraterrestrial life -- is among the marvels shared this weekend at a Santa Clara gathering of astronomers, astronauts and science fiction fans.

The theme of the three-day SETIcon event: the exploration of universe and the quest to find life beyond Earth.

Scientists agreed that the neighborhood is looking a lot friendlier.

What began as a trickle of new planet discoveries a decade ago has turned into a torrent -- and not all places are rocky, gaseous or just plain weird.

Of the 3,000 or so candidate planets found so far by Kepler -- a NASA mission designed to find Earth-size planets around other stars -- several hundred of them share one special characteristic: a density of nearly 1 gram per cubic centimeter.

That's the density of water.

And, it could be prime real estate, said longtime planet hunter Geoff Marcy of University of California-Berkeley, speculating that these planets are composed of 30 to 70 percent water. "They're not pure rock," he said. "They're not pure gas. These are planets that are composed almost certainly of water."

carbon can break apart and re-assemble into many forms. Maybe, for instance, amino acids. Or proteins. Or even DNA, the blueprint of life.

LOL! Not without some help.

NASA scientists ponder how many aliens can dance on the head of a pin?

And just WHO is to say that ‘alien life’ is, somehow MORE intelligent?

The theory goes something like:

Any alien life that comes to earth has to be more intelligent than ours because they have mastered interstellar travel where we have not.

I don’t think they apply that line of reasoning to finding any kinds of life on other planets. I mean, no one is saying that some bacteria on a planet 300 million billion miles from here is more intelligent than us.

More intelligent than the liberals, maybe...but not us.

Just the same , old, eugenics philosophy.

I have been a great proponent of the SETI radio program
(listening for radio signals from ET).
There was mention of listening as far back as the late 50s.
The theory was that high power VHF TV signals, started in the late 30s, and not reflected by the ionosphere, could have reached a distant star system and a reply directed back our way.

I am, however, quite skeptical that Earth has been visited, or that any intelligent life lives within 20, or more, light years of earth, despite all the chattering on Kook to Kook AM.
Within the rest of my lifetime, I would like to be proven wrong.

If “they” come “here” and are not from a planet in our system they have interstellar travel.

Has nothing to do with eugenics - and very likely nothing to do with reality at all.

I’m just wondering how long until we get a picture of the ancient alien guy from history channel posted on this thread?

We need to find intelligent life in Washington D.C. first!

Well, if the Darwinists and the Big Bang theorists are right, then there must be life out there on countless planets, and some would be less intelligent, some more intelligent. By that reasoning, though, we should have seen some sign of it by now. Instead, we’ve got zip, zilch, nada.

I think their fundamental hypotheses are flawed, so I’m not holding my breath for an alien transmission or UFO landing.

Have you actually MET an Obama voter? (If you had, you'd know the answer to your question is a resounding YES, they are!)

Intergalactic voyeurism just doesn't work for me. Wake me up when they can put people on Mars.

Any alien life that comes to earth has to be more intelligent than ours because they have mastered interstellar travel where we have not.

Visiting aliens wouldn't have to be any more intelligent than humans to have mastered interstellar travel. Their cultures would simply have to be older. We'll likely master interstellar travel ourselves (provided we don't kill ourselves off first) within another hundred years.

You're assuming that they'd even want to contact a violent, insane species like us.

Looking at us from a technologically superior extraterrestrial's viewpoint, we might well be worth studying or keeping an eye on, but open contact would probably be out of the question. Wouldn't want to risk being contaminated with whatever's infected us, you know?

If they were technologically advanced enough to get here, I doubt we would be any threat to them, no matter how violent or insane we were. The Aztecs were violent and insane, but the Spanish had no problem subduing them and putting them to work for them.

Point taken, but we're just having an intellectual exercise here.

What would be the upside in making open contact with earthlings for an advanced extraterrestrial race? I can't think of any off the top of my head.

Pets? Slaves? Inter-species concubines?

I don’t know and I don’t really care much, since I don’t think there are any alien races out there. I think we’re it.

Not to belittle you, but do you have any inkling of the astronomical odds against that being the case?

Try to wrap your head around this....there are around 100 billion stars in the average galaxy. Scientists are now finding that nearly all stars have planets of one type or another - many with the same density as ours (which indicates the presence of water).

There are more galaxies in the known universe than all the grains of sand on every beach on earth.

I know it's an impossible task, but just try to conceptualize 100 billion stars for every last grain of sand on this planet. EACH of them with planetary systems.

Heck, just try thinking with the fact that there are 100 billion suns in our own galaxy, MOST of them with planetary systems. That's 100 billion chances for life to develop in some place other than here. Look at the sheer numbers involved with this for a while, and you'll realize why the scientific community no longer asks the question "if" there's life beyond our planet, but "where" it is.

Yet, the entire argument rests on believing that life can spontaneously arise and organize itself out of non-life. If that is not possible, then you can have 100 billion, 100 trillion, or 100 zillion chances and it doesn’t matter one bit.

No one's ever proved that life spontaneously arose and organized itself on this planet. I'm afraid that's not the basis for the entire argument that life exists elsewhere in the universe.

In fact, the question of 'how' life arises, is completely irrelevant and non-sequitur to the conversation about life elsewhere in the universe. The sheer scale of the numbers involved with the question, argue for a 100% certainty that life exists, and is even abundant, throughout the universe.

We don't need to know how life arises to examine the question of extraterrestrial life. Our planet is proof that life can and does arise.
