Saturnís Moon Titan Has Salty Sea
americanlivewire.com ^ | Will Phoenix

Posted on 07/05/2014 9:53:03 PM PDT by BenLurkin

According to new findings just published in this week’s edition of the journal Icarus, NASA’s Cassini Mission has brought to light new evidence of an actual ocean inside Titan, Saturn’s biggest moon. Furthermore, the ocean in question might even be as salt-laden as Earth’s Dead Sea.

This is but the latest discovery resulting from an analysis of data on topography and gravity gathered during the past decade. Scientists discovered that an extremely high density was needed for the surface ocean of Titan to explain the information on the gravity. This means that Titan’s ocean has to be a very “salty brine of water mixed with dissolved salts” like potassium, sodium or sulphur. The team also learned that density of Titan’s outer ice shell differs from spot to spot. This indicates that the shell is currently freezing solid.

Linda Spilker, Cassini project scientist, concluded: “Titan continues to prove itself an endlessly fascinating world. With our long-lived Cassini spacecraft, we’re unlocking new mysteries as fast as we solve old ones.”

If this theory holds up, and no inlet of freshwater is found feeding into it... ...the odds of finding life on Titan just went way down.

(On the other hand, if reliable inlets of fresh water can be found, then the choice of locations where a probe should be sent just got considerably simplified....)

Life doesn’t have to be like us to be life. I’m sure life will find a way to breathe salt water.

...I’m talking abut water as briny as the Dead Sea... That’s way different than normal salt water in Earth’s Oceans....

Because we all know life can’t adapt to adverse conditions.

Who’s to say it can’t happen?

http://en.wikipedia.org/wiki/Outsiders_(Known_Space)

Listening to the audiobooks, they were creatures made out of liquid hydrogen, who feed off artificial or natural sunlight, from what I remember.

I'm just saying it's much harder, that's all.

And, I'm basing my statement on what has been seen with searches for life on the Dead Sea.

I wish people wouldn't stuff words into my mouth that I haven't said...

We can't even explain the origin of life on earth.

The problem with explaining the origin of life is, how did self-replicating molecules arise? DNA is very complex. Even the simplest life forms require some such complex molecules. But how could such complexity have arisen? There must have some intermediate forms, but we don't know what it was.

Once you get complex self-reproducing molecules, though, natural selection can do the rest in terms of making increasingly complex life forms.

Perhaps the intermediaries to get to DNA no longer exist. It would be like if we built sentient machines and then we died out. Later, the machines might wonder how they originated. The intermediate step, us, would be gone.

The results from searching for life in the Dead Sea, which Titan's oceans are being compared to in this article.

Really, people, it's called the "Dead Sea" NOT because life finds it easy in there! Life can be found, but only in very particular areas where the water chemistry is different that what is found in the vast majority of it....

Inside each molecule there is something that makes it tick, and something inside that,
and something inside that, and on and on and on. The deeper we look for the end
the more we find and the longer we have to wait for technology to catch up
so that we can see more. And if we find the deepest hidden secret behind the exact center
of each molecule, there's something that makes it tick too. God.

It's an age-old question: How far down does it go? There was a Daredevil comic in the mid-'60s where one of his enemies got hit by a shrinking ray and kept getting smaller and smaller until *poof* he was gone.

That stuck with me.

The Dead Sea is home to billions of organisms. It is literally teaming with life.

In Titan's sea, there may also be "very particular areas."

Take a number and divide it by two. Take that number and divide it by two. Continue dividing by two. Call me when you get to the end, lol.

What's the old indian saying? It's turtles all the way down.

We need a probe that can scoop up samples and bring them back.

In evolutionary terms, the Dead Sea is minutes old. Life that evolved to live in the Atlantic has yet to adapt to such brine. If such a high salt sea were all that existed, I don’t doubt that originating life could deal with it.

Did you mean: Outsiders (Known Space)?

Look for Outsiders (Known Space on one of Wikipedia’s sister projects.)

Wikipedia does not have an article with this exact name. Please search for Outsiders (Known Space in Wikipedia to check for alternative titles or spellings).

FYI:
http://screencrave.com/2013-02-13/the-incredible-shrinking-man-remake/

‘The Incredible Shrinking Man’ Is Getting A Remake.

MGM announced today (February 13th, 2013), that they had purchased the rights to the classic science-fiction novel The Shrinking Man by Richard Matheson for a planned film adaptation—making it an ostensible reboot/ remake of The Incredible Shrinking Man, the 1957 classic sci-fi film that also adapted the novel.

According to /Film, Universal had previously owned the rights to the story “for decades,” and until recently had planned to have Brett Ratner direct Eddie Murphy in a comedic remake in which Murphy would have played a magician who shrinks due to magic, which is pretty much the worst idea in the world ever.

Now that the rights have lapsed and MGM has snapped them up, the film studio has even managed to hire Richard Matheson himself, now 86 years old, to write the script with his son, Richard Matheson, Jr.

regarding the subthread:

Sea Monkeys, Ferns and Frozen Frogs: Nature’s Very Own Resurrecting Organisms

links

http://deadsea.com/info/dead-sea-animals

Unlike most other seas and lakes throughout the world, the Dead Sea is not teeming with life. The reason for the lack of organisms is the high salinity of the sea, which is approximately 36%, making it one of the highest salt content lakes in the world. That is not to say that life does not exist in the Dead Sea although it is called the Dead Sea for a reason. Unfortunately, there is not a long list of Dead Sea animals to provide as there is a lack of life.

What Dead Sea animals do exist are those that seem to spring to life during a particularly rainy season. The floods from the rain wash sources of life into the sea, providing some form of life to be had. That is not to say that life disappears completely when the rainy season has dried up and gone away. In fact, scientists have recently discovered several craters along the sea bed that spew fresh water filled with bacteria. What once seemed like a barren atmosphere is now crawling with bacterial organisms.

It's turtles all the way down.

I love that story. The old lady in the audience at the astronomy lecture says modern astronomy is bunk, and the earth is really supported on the back of an elephant standing on a turtle.

The astronomer thinks he's got her when he asks, "What's the turtle standing on?"

She says, "You can't fool me, young man. It's turtles all the way down."

"[closing soliloquy narration] Scott Carey: I was continuing to shrink, to become... what? The infinitesimal? What was I? Still a human being? Or was I the man of the future?

If there were other bursts of radiation, other clouds drifting across seas and continents, would other beings follow me into this vast new world?

So close - the infinitesimal and the infinite.

But suddenly, I knew they were really the two ends of the same concept. The unbelievably small and the unbelievably vast eventually meet - like the closing of a gigantic circle.

I looked up, as if somehow I would grasp the heavens. The universe, worlds beyond number, God's silver tapestry spread across the night. And in that moment, I knew the answer to the riddle of the infinite.

I had thought in terms of man's own limited dimension. I had presumed upon nature. That existence begins and ends in man's conception, not nature's. And I felt my body dwindling, melting, becoming nothing.

My fears melted away. And in their place came acceptance. All this vast majesty of creation, it had to mean something. And then I meant something, too. Yes, smaller than the smallest, I meant something, too.

To God, there is no zero. I still exist! "


..........The Incredible Shrinking Man - 1957

One of best sci-fi movies made. Guaranteed they'll screw up the remake and I bet they never mention God.

Great movie. It's a good topic to hang a tale on.

I always wonder though what happens when you get small enough for quantum effects to kick in. It's not just a matter of scale; it's a whole new set of rules.

There's a good scene in Faust where he is trying to translate "In the beginning was the Word" from the Greek, and he can't decide how to translate "Logos."

He says "Word" is too weak. He tries "Mind," "Power," "Action," and finally drives Mephistopheles crazy, who has snuck into the room on the form of a poodle.
