Can we find out if *he* has a molten core?

Girls refuse to view stripping as yet another way the patriarchy keeps women down. Now it's art, a celebration of the female form - an act of aggression in which men are reduced to human ATMs - and it gives those who've swung on poles instant hipster cachet.

Even if it does have a molten core (3, Informative)

The plate tectonics that would have ensued from having an active core (like Earth's) has ceased, for quite a long time too.

looseBits (556537) | more than 11 years ago | (#3516181)

Measuring fluctuations in the Moon's size obviously tell you if it is solid or not but what about looking at the magnetic field. If the core of the Moon is liqued, then you wouldn't you see a large magnetic field from the free flowing ions in the core? That is what is responsible for the Earth's field.

Re:Aren't there easier tests? (0)

Anonymous Coward | more than 11 years ago | (#3516221)

Perhaps it isn't magnetic.

Re:Aren't there easier tests? (2)

CheshireCatCO (185193) | more than 11 years ago | (#3516935)

The Moon appears to once have had a magnetic field, but if our theories of field generation are right, it's rotating too slowly now to have any real field.

Re:Aren't there easier tests? (1)

martyn s (444964) | more than 11 years ago | (#3520099)

It rotates at a rate of about once a month. That's why the same side is always facing us. The word "rotate" here is a little misleading. The moon acts just like a ball attached to a string acts when it is swung around. The side that the string is attached to is always facing the center, or your hand which is rotating the string. So technically the moon is rotating because it faces the opposite direction every ~30 days but it's not just a coincidence that the rotation of the moon is exactly equal in time to it's revolution around the earth. Like a ball on a string.

Re:Aren't there easier tests? (2)

CheshireCatCO (185193) | more than 11 years ago | (#3520191)

Yes, exactly. This rotation is thought to be too slow to support a strong field, particularly in a body with such a small, if any, core.

Re:Aren't there easier tests? (1)

jungd (223367) | more than 11 years ago | (#3545669)

I think the poster meant the rotation of the core within the crust (which would produce a field) - not that of the moon around the earth.

OPEN SOURCE MISCONCEPTIONS
By Serial Troller [slashdot.org]

Myth: Open Source is written by heterosexuals.

Fact: All Open Source development is done by raging homosexuals. The more flaming examples include Anal Cox, Linus Turdballs, Eric Ass-Reaming Raymond, and the entire Slashdot crew. The ringleader of the slashdotters, a man named CmdrTaco, engages in a practice known as Taco-snotting, along with his faggot-buddies Jeff Homos Bates and CowBoiKneel.

Myth: Open Source is written for heterosexuals.

Fact: Using Open Source software can cause suppressed homosexual fantasies to surface, leading to all out flaming faggotry within 6-8 weeks. Anecdotes of otherwise hetero men turning queer are far too numerous to count, but a few examples stand out. In one case, a man was arrested loitering outside an elementary school and making sexual overtures to several children: he quickly confessed that shortly after installing the Mozilla browser on his computer, he began to have uncontrollable urges to, to put it simply, have his cock sucked off by little boys. He soon met several other like-minded men through discussions on the Bugger Zilla mailing list (all already homosexuals), who together kidnapped a total of seven children whom they brought back to their apartment and sodomized. The other two men are still at large and believed to still be using Mozilla.

Myth: Open Source is multicultural.

Fact: Open Source is openly racist [slashdot.org].

Myth: Open Source is democratic.

Fact: Open Source is controlled by a few narrow-minded zealots (mentioned throughout this post), most of whom are either Communists, Stalinists, Nazis, or Fascists. Additionally, Open Source supports terrorism.

Myth: Open Source is tolerant of religious preferences.

Fact: Open Source developers regularly engage in holy wars over the superiority of various Open Source projects, such as the Emacs program (preferred by Christians) versus vi (used mostly by neo-pagans and Satanists); or the KDE desktop (a favorite among Muslims) versus the GNOME project (particularly favored by Jews). Posts initiating crusades or jihads against other developers can be found regularly throughout the newsgroups and mailing lists.

Myth: Open Source is tolerant of sexual preference.

Fact: See above. Either you are a homo, you become a homo, or you never visit Richard Stallman alone in his office and hope to God you never meet him on the street at night.

Myth: Open Source is tolerant of political differences.

Fact: Open Source is an anarcho-communist philosophy bent on the destruction of capitalism. The very same Richard Stallman, a man whose name is disturbingly reminiscent of Stalin, has stated several times in public that his vision includes the subjugation of all who own intellectual properties under the jackboot of the GPL. The GPL is a pernicious piece of literature lifted straight from Karl Marxs Communist Manifesto, and is fortunately banned in many democratic nations.

* * * * * UPDATE * * * * *

Myth: Open Source programming is a harlmess, healthy activity.

Fact: Open Source programming has been known to lead to massive obesity [cowboyneal.org], violent tendencies with an obsession with handguns [tuxedo.org], paranoid-delusional ranting [slashdot.org], and in severe cases, complete insanity [slashdot.org]. If anyone you know is thinking about going Open Source, stop them before its too late!

Silly scientists.. (1, Funny)

Anonymous Coward | more than 11 years ago | (#3514863)

It was proved (through observation) many years ago that the moon is made of cheese. The reason the government keeps the moon "rocks" is because they're so delicious. Moon cheeseburgers are the best food in the solar system... and don't forget the yummy bacon and moon cheesefries.

Used to have a molten core. It has no electromagnetic field any more (they are closely related), and hence gets hit by all the asteroids (big and small).

"In nature, magnetic fields are produced in the rarefied gas of space, in the glowing heat of sunspots and in the molten core of the Earth. Such magnetism must be produced by electric currents, but finding how those currents are produced remains a major challenge."

IF we had a moon colony how would a molten core compare to solar cells as an energy source?

Might be worth looking at.

Re:Energy (2)

doooras (543177) | more than 11 years ago | (#3514967)

A molten core would allow for continuous Geothermal energy (methinks) which would be more useful than solar, since any given location on the moon is only facing the sun for half of each month.

BTW... love the sig.

Re:Energy (2)

Debillitatus (532722) | more than 11 years ago | (#3515197)

...continuous Geothermal energy...

Yeah, this would be the Holy Grail of power sources for a moon colony. There would be a lot of energy down there, much more than we could use.

The only problem I could see is the same one which stops us from using geothermal effectively here; we can't drill deep enough to get a large enough temperature differential to make it worthwhile. Perhaps some engineer could elaborate on this...

Re:Energy (3, Insightful)

Christopher Thomas (11717) | more than 11 years ago | (#3515411)

IF we had a moon colony how would a molten core compare to solar cells as an energy source?

Solar would be better.

Especially with no atmosphere or weather to degrade the incoming sunlight, solar cells work quite well.

Geothermal is a pain to work with under the best of circumstances (you can only build a large-scale plant (no small power sources)), and even if the moon has an energy-producing core (tidally kneaded or (like Earth's) radioisotope-powered), the amount of energy flowing out of it is small compared to Earth's (no volcanism or rapidly convecting mantle). This means that the yield from geothermal on the moon will under the best of conditions be much lower than on Earth.

Given that solar power is so convenient, I don't see any strong reason to use geothermal. Power storage for half a month isn't *that* hard, and if you need enough power to make storage impractical, you can put big mylar mirrors in orbit around the moon to reflect enough sunlight to supply your photocells (probably cheaper than a power cable around the equator).

Re:Energy (2)

CheshireCatCO (185193) | more than 11 years ago | (#3516962)

If you want to use geothermal energy, you need active geologic activity at the surface. The Moon doesn't have that, based on the many, many observations we've made of the surface. If there is a molten core at all, it's a tiny fraction of the volume, deep in the interior.

Zelet (515452) | more than 11 years ago | (#3515067)

With a warm core, there is possibility (although slim) for life to survive in air tight pockets beneath the surface and toward the warmth of the core. This would be a great discover for mankind, however slim the odds.

Re:life on our own moon (1)

!splut (512711) | more than 11 years ago | (#3515571)

Mm. Don't hold your breath. There may be a possibility that life could survive in airtight pockets toward an interior warm core, but I don't see how there's any possibility that it could evolve there. ...or that we could find it without dismantling the moon.

Geothermal maybe? (2)

hackwrench (573697) | more than 11 years ago | (#3515532)

AllMightyPaul (553038) | more than 11 years ago | (#3516003)

Having a molten core would NOT lend support to the theory that the moon splintered off of the Earth. In fact, the non-existence of a molten-core would better lend support to that theory than a molten core. This is simply because if the moon splintered off of the earth, it is going to be one giant rock. How does one get a molten core from just a rock? Does anyone else see what I'm saying?

Re:No way (1)

arsenick (115431) | more than 11 years ago | (#3516088)

No way yourself. It wouldn't be a giant rock. It'd be the product of gravity acting on a cloud of dust ejected in space after the collision, much like Earth and the Sun were formed. Did you really think we thought a large object hit Earth, and ejected a perfectly spherical rock?

Re:No way (2, Informative)

Transcendent (204992) | more than 11 years ago | (#3516111)

What a lot of people are missing is the fact that the moon is in such an orbit that only one side faces us at any given time (look for yourself.... heh). This orbit is far to delicate for any captured rock, or huge chunk of earth that was smashed off by an asteroid could create, it had to have been that the moon was an actual part of the earth, but gave the earth a lop-sided form. So centripital (spelling?) force caused that chunk to rip off from the earth, creating the moon we have today.

(no, it doesn't have to be necessarily a chunk, but most likely a big scoop pf molten rock... from when the earth was in a molten state.)

Did you really think we thought a large object hit Earth, and ejected a perfectly spherical rock?

Well thats how everything started. Basically huge chunks of rock slammed together to make the planets, and over time, smaller ones filled in the gaps, the pressure created a molten core, and the core smoothed everything out.

Re:No way (3, Interesting)

CheshireCatCO (185193) | more than 11 years ago | (#3516996)

Darwin's (no, George Darwin, Charles's son) idea about planetary fission to form the Moon doesn't work. There's insufficent angular momentum in the system to make it work. The giant impact model is the ONLY model that makes sense right now. (The tidal locking of the Moon causing it to show us one face at all times has nothing to do with anything.)

In fact, the original poster is correct: if the Moon formed in a giant impact, it appears that it should be almost all rock akin to Earth's mantle. The iron and other metallic elements would have sunk into the interior of the Earth, being lost to the disk of debris what would go on to form the Moon.

Re:No way (2, Interesting)

shrikel (535309) | more than 11 years ago | (#3517882)

The earth IS in a molten state as we speak! There's a little crust on the outside, but, proportionally speaking, it's many many times thinner than the shell of an egg. The earth could be hit by a large celestial object TODAY, (even a 200-mile wide blob of frozen ammonium, which is VERY cold) and tomorrow you wouldn't be able to tell that the earth had EVER had a crust. It's not that the force of the impact would melt the entire crust, it's just that it would break the shell and let all the hot insides come out and melt the crust.

drudd (43032) | more than 11 years ago | (#3518277)

Yes, this is true... it also has nothing to do with how the moon formed. Angular momentum transfer from tidal forces automatically forces an orbiting body into just such a configuration. It's called being tidally locked. This same process has caused the earth's rotation to slow, and to increase the average radius of the moon's orbit.

The molten core of the earch IS rock - molten rock! i.e. that stuff you see coming out of a volcano is very hot, and hence liquid, ROCK. That comprises the major part of the earth's mass.

The "Moon": A Ridiculous Liberal Myth (-1, Troll)

Anonymous Coward | more than 11 years ago | (#3516878)

It amazes me that so many allegedly "educated" people have fallen so quickly and so hard for a fraudulent fabrication of such laughable proportions. The very idea that a gigantic ball of rock happens to orbit our planet, showing itself in neat, four-week cycles -- with the same side facing us all the time -- is ludicrous. Furthermore, it is an insult to common sense and a damnable affront to intellectual honesty and integrity. That people actually believe it is evidence that the liberals have wrested the last vestiges of control of our public school system from decent, God-fearing Americans (as if any further evidence was needed! Daddy's Roommate? God Almighty!)

Documentaries such as Enemy of the State have accurately portrayed the elaborate, byzantine network of surveillance satellites that the liberals have sent into space to spy on law-abiding Americans. Equipped with technology developed by Handgun Control, Inc., these satellites have the ability to detect firearms from hundreds of kilometers up. That's right, neighbors .. the next time you're out in the backyard exercising your Second Amendment rights, the liberals will see it! These satellites are sensitive enough to tell the difference between a Colt .45 and a .38 Special! And when they detect you with a firearm, their computers cross-reference the address to figure out your name, and then an enormous database housed at Berkeley is updated with information about you.

Of course, this all works fine during the day, but what about at night? Even the liberals can't control the rotation of the Earth to prevent nightfall from setting in (only Joshua was able to ask for that particular favor!) That's where the "moon" comes in. Powered by nuclear reactors, the "moon" is nothing more than an enormous balloon, emitting trillions of candlepower of gun-revealing light. Piloted by key members of the liberal community, the "moon" is strategically moved across the country, pointing out those who dare to make use of their God-given rights at night!

Yes, I know this probably sounds paranoid and preposterous, but consider this. Despite what the revisionist historians tell you, there is no mention of the "moon" anywhere in literature or historical documents -- anywhere -- before 1950. That is when it was initially launched. When President Josef Kennedy, at the State of the Union address, proclaimed "We choose to go to the moon", he may as well have said "We choose to go to the weather balloon." The subsequent faking of a "moon" landing on national TV was the first step in a long history of the erosion of our constitutional rights by leftists in this country. No longer can we hide from our government when the sun goes down.

What in the world does "molten core" have to do with "split off from Earth"?! The thermal time constant of the Earth is only a few million years -- the core isn't molten because the Earth is still cooling, it's molten because of the decay of radioactive nuclei, primarily uranium. The moon's thermal time constant would be even shorter, so if the core is still molten, it would have nothing to do with a violent creation.
