Pieces of Ancient Earth May Be Hidden On the Moon
swestcott brings us a story from Space.com about the possibility of finding evidence for ancient Earth life on the moon. A team of scientists has published work confirming that meteorites originating from Earth could have remained sufficiently intact while colliding with the moon to allow the survival of biological evidence for life. Quoting:
"Crawford and Baldwin's group simulated their meteors as cubes, and calculated pressures at 500 points on the surface of the cube as it impacted the lunar surface at a wide range of impact angles and velocities. In the most extreme case they tested (vertical impact at a speed of some 11,180 mph, or 5 kilometers per second), Crawford reports that 'some portions' of the simulated meteorite would have melted, but 'the bulk of the projectile, and especially the trailing half, was subjected to much lower pressures.'"
Shit, I spent so much time thinking of something witty to put in here, I'm not first anymore!
It's a... oh, right.
Why the hell would you model an asteroid with some improbable shape like a cube?
Weaselmancer
rediculous.
Here's a good reason to go back to the moon if there ever was one. Or at the very least a better excuse than we've had so far.
Though the survival of the species is always a good reason...

Can just see the reaction to this. Life can't survive elsewhere in the solar system. It's all pieces of Earth that got blown out.
Another theory is that Moon was tugged into place to stabilize Earth.
You are being MICROattacked, from various angles, in a SOFT manner.
So aliens must exist! If they didn't exist the meteorites would be lying on the ground, not "hidden".
We're whalers on the Moon
We carry a harpoon
But there ain't no whales
So we tell tall tales
And sing our whaling tune

The collision theory is pretty much universally accepted by now. I'm not sure it requires a complete breakup of the planetoid that hit earth.
ALso, looking at that site... the first theory... "The present Pacific Ocean basin is the most popular site for the part of the Earth from which the Moon came." I can't think of any reason why this is even remotely valid given plate tectonics and several billion years.
I can confirm that there are pieces of the Earth in the moon. Somewhere in the back of my closet, I keep a fossil of a ancient platypus that astronauts brought down from the moon a few decades ago. Looks an awful lot like Hexley.
McCain/Palin '08. Now THAT's hope and change!
Its a sign. Timecube.
and on top of that, why would you partition it into 1000s of cubical rooms with diabolical traps like acid jets and razor wire?!? who knows how that happened?!?!? Blame the corporate machine!
Why don't these scientists do something useful for a change and tell us where to drill! I just bought my Hummer and now I can't afford the gas.
Look on the bright side. You might not be able to aford to drive it but at least your dick's bigger.
I'm having problems accessing /. homepage and I'm posting this from coral cache. oh! ..Wait.. I for one welcome our Chinese ddos overlords?

Or if you bother to look up at its crater-covered surface...
Was it the same cat?
A cube is pretty much the worst shape possible when it comes to distributing the force of an impact evenly across the entire object
Not true; What about those crystalline spacecraft that the Kryptonians use to send their infants to Earth in? They have all sorts of jutting and produding suraces.
The wheel is turning, but the hamster is dead.
The dead biomatter is really alien lifeforms and the gov't is feeding the press this cover story about how the stuff they found is from "ancient earth" so they don't drive the populace into a panic by saying they found alien life and risking the loss of control over their various theocracies. And Roswell really happened and the alien autopsy video was totally not faked. It's all a conspiracy, dude! See you at Area51.
If not, it is not of much use knowing they could exist. After all the article says the meteorites would be small, fractured and covered by dust and later impacts. IMO expecting to stumble on them by accident on a return trip to the moon, as it says, is way too optimistic.
This study is trying to tell us that if we find life on the moon, we can still be the center of the universe. But 3800 million years ago, our planet was still mostly a molten rock. This is evidenced by all the dating methods we have (IE, there are no rocks older than 3800 million years).
How does a molten rock have life to spew onto its moon?
If we find some tiny bit of life on the moon, make no mistake: it means life is not from here. And why should anyone be surprised?
Evolution feels pretty weak these days. Intelligent design (without the "I know who God is" part) is a much better model. Look I'm a programmer: I like models. The one that is the best reflection of reality wins, regardless of its origin. I don't like the Church any more than you do, but DNA is too much like a computer program for me to ignore.
And to think it developed here, spontaneously!? Look at all the instructions it is capable of: brains, lungs, socialization? Did you know DNA is what makes a lot of the choices in your brain? Right, in every neuron, every time it fires, messages go into the nucleus (that's the dna's housing and equipment) and get translated by RNA and DNA... the resulting parts of the neuron that fire are due to the response from the DNA!
We use this same thing to make RNA computers that can do massive calculations in a fraction of the time it would take our current PCs to do it (well, the setup takes a while, yuk yuk.) This building blocks of life, which came about in a cave as the world cooled off from its volcanic eruptions, just randomly have supercomputing ability?!
... come on. It's incredible. That means unbelievable. Don't believe it. They're feeding you lies. Look behind the lies, look to the motivation.
"Pieces of Ancient Middle Earth May Be Hidden On the Moon"
Presumably the collision needed to splash a bit of rock off the Earth, through its atmosphere, up its gravity well to the moon would be at least 6 times as forceful as the collision with the moon.
They'd have to show that bits of organic material would survive both collisions to make it plausible.
Then explain how you would go looking for the few unlikely surviving chunks on something the size of the moon. Which by the way keeps getting hit all over with rocks from everywhere else, hence all the dust and craters.
Good luck with that.
Or is this just one of those things like string theory where you get to make up a hypothesis that you can't possibly actually falsify?

-- Gnus. Lots of Gnus.
There was a great collision and the Moon was formed from the Earth, so the Moon is the Ancient Earth.
Right ?
We are Dead Stars looking back Up at the Sky
Directly from the page you apparantly googled (since you don't seem to have read it):
A detailed comparison of the properties of Lunar and Earth rock samples has placed very strong constraints on the possible validity of these hypotheses. For example, if the Moon came from material that once made up the Earth, then Lunar and Terrestrial rocks should be much more similar in composition than if the Moon was formed somewhere else and only later was captured by the Earth.
These analyses indicate that the abundances of elements in Lunar and Terrestrial material are sufficiently different to make it unlikely that the Moon formed directly from the Earth. Generally, work over the last 10 years has essentially ruled out the first two explanations and made the third one rather unlikely. At present the fifth hypothesis, that the Moon was formed from a ring of matter ejected by collision of a large object with the Earth, is the favored hypothesis; however, the question is not completely settled and many details remain to the accounted for.
Emphasis mine, and as it says the most likely theory is the collision theory. It fits all the known data and computer models show how plausible it is compared to the other theories.
Okay, I'm starting to freak out now. Today we have articles about one of the Poles melting, these new Neural Interface headbands, and now we're starting to talk about some seed of life that's related to our moon being formed. Plus, I just got finished watching Neon Genesis Evangelion. Are we about to experience the Second Impact? Maybe it's just the mind screw I've subjected myself to, but the pieces are fitting together WAY too much for this AC's mind to handle.
The article doesn't mention how these earth-originated asteroids become space-borne, except a brief mention of the "Late Heavy Bombardment." I would think that pieces of earth that are sent into space by other asteroids hitting earth, would be subject to *far* more stress, heat, and general voilence in being struck hard enough to reach escape velocity, than they would on a simple re-entry.
Surely the impact event and associated energy required to eject the matter from Earth's stronger gravity and much thicker atmosphere, would be far worse when compared to the landing on the moon, no? (I know it's not a direct comparison, but consider how much fuel the Apollo missions in the massive boosters used to get out of Earth's gravity, versus how little they used to decelerate down to the moon's surface, carried on board the relatively small lander.)
Love many, trust a few, do harm to none.
Just bolow the fucking shit up, now that the ice on the poles is going to melt, the high tide caused by the moon would make us sink.
I mean, it's either that, or hurrying up with the creation of LHC-0001.
What could go wrong????
Quiet, secluded location. Clear skies. Perfect for the adventurous. Ideal for your country estate or getaway. Some restrictive covenents; but they aren't being enforced. Possibility of well water on site. Bring all reasonable offers.
For all intensive purposes, "whom" is no longer a word. That begs the question, "who cares"?

Do you want to engage in some kind of debate about this, or just resort to name calling? What about my statement do you think is wrong, and why?
OK, Salty- no more name calling.
The NaCl crystal is cubic. A "square", if you will.
And you ARE full of it.
Luckily for you (perhaps unlucky for the rest of us) yours is in solution.
