It's raining diamonds on Neptune & Uranus 117

Posted by Hemos from the i-think-that'd-hurt dept.
Alec Muzzy writes "The U of C of Berkeley has reported that on Neptune the intense heat and pressure of the atmosphere likely creates diamonds out of methane which then fall like hail on the gas giant. " Interesting reasons why - but isn't it a Arthur C. Clarke book that postulates, back in the 80s, that the center of of the gas giants are enormous diamonds - like the size of the earth?

    If it wasn't for DeBeers (sp?) we wouldn't have the high prices we have now. They have been hoarding and buying up diamonads to decrease the supply to the consumer and drive up prices for years.

    I guess a diamond will be forever, if DeBeers buys it.
  • There is nothing inherently valuable about diamonds right here on earth. The supply and distribution of diamonds is rigidly controlled by DeBeers in order to maintain artificially high prices. The diamond business is quite odd - you should investigate it sometime. Diamond distributors must take what they are given, and the prices are always artificially high.

    Rumors persist that Russia maintains huge caches of cut diamonds that have not been released onto the market, most likely in exchange for some sort of payment from DeBeers.

    Even if the Russians did flood the market just to spite DeBeers, it would be detrimental for them as well, as the increased supply would lower prices considerably.

    Not to insult the happy brides of the world, but if supply and demand really ruled the market for diamonds, their rings would probably lose 90% of their value.

    Methane is CH4. One carbon in the middle surrounded by four hydrogens, arranged in a tetrahedron. Diamond is tetrahedronal structure -- one C in middle surrounded by 4 other C's in tetrahedron, each C in turn surrounded by four other C's, each of which is surrounded by 4 other C's, each of which is surrounded by 4 other C's ..... etc, etc, etc, this is the formation of a tetrahedronal "fabric" matrix. Under extreme heat and pressure, the CH4 dissociates, leaving one C nucleus plus 4 H nuclei (protons) swimming in electron soup. When temp and pressure subside at the proper pace, the protons find enough electrons to pair up as H2 molecules and the carbons either settle into a nice tetrahedronal matrix if you're lucky, forming diamond crystal, or if you're unlucky, a pile of graphite flakes which you can then use to lube your key locks or brake and gear shifter cables on your mountain bike.

    Considering the pressure and temperature necessary to create diamonds in this way, as well as the expense of interstellar travel and the fact that the diamonds formed in the experiment were in the form of diamond dust, I don't expect to see any diamond-harvesting missions to the outer planets any time soon. It would probably be cheaper and easier to manufacture diamonds here on Earth.

    This is still useful information, though, as it may explain Neptune's strong internal energy source.

    This story presents a perfect opportunity to point out to people that Diamonds are not particularly rare. There is a myth of scarcity fabricated by the DeBeers cartel, to keep the price of diamonds up. Obviously we don't find diamonds out in the driveway, so they are not a common rock, but the DeBeers cartel has cornered the market on raw diamonds as mined from the earth, and they lock away most of the annual output of these rocks.

    Diamonds are the same kind of valuable item as Beanie Babies, for much the same reason. Don't ever rely on them as an investment vehicle. There are other precious minerals which are far more secure, whose value is not dependent on the arbitrary actions of a single corporate interest.

    The on-topic gist of this message I am typing is to make clear to everyone that no, we shouldn't shoot off into space to grab all the diamonds in space. All we need to do is bust a monopoly and there will be plenty of diamonds for all who want them.

  • Harvesting diamonds - easy. Just crash something large and heavy into it, then scoot around picking up the pieces that are flung off into space.

    Given NASA's recent activities, I'd imagine they're quite skilled at crashing things into distant planets.

    So we're half way there, at least.

    Question is : what can we crash into it to make a big enough diamond splash?

    Hey - maybe there is a use for AOL disks after all!

  • Yeah, and also you'll need to make an alloy that is stronger than diamonds and can withstand the intense pressure that can CREATE diamonds from GAS. You're gonna have a helluva time.

    Besides what we are finding as probes go deeper into space is that the pressure becomes so intense that they just implode anyway, so when we can travel to the core of neptune or uranus and back again, it will mean leaps and bounds for space exploration.

    Sure, if we could get the diamonds out of there it would be great, but uh, they are in an area of _INTENSE_PRESSURE_, thats why they are diamonds, after all, and thats going to make it a real pain in the butt to get them out, since you can't just send in a gigantic retractable claw, (it would get squeezed into nothing) Although maybe you could hold coal close to where the pressure is extremely intense and watch the coal turn to diamonds.

    Luck doesn't have much to do with it. If you draw a graph of temperature against pressure, there is a very clearly defined P-T area where diamond is the stable form of carbon. At normal conditions on the earth surface, graphite is more stable than diamond, but the spontaneous conversion of diamond to graphite has such a slow theoretical rate, that you'll never see it happen.

  • Yes, Arthur C. Clarke did propose the idea of diamond-core gas giants, but I think he got it from some research similar to this. The idea was first mentioned in either 2001, or 2010, and became a plot point in 2063, when a mountain-sized chunk of diamond winds up embedded in the surface of Europa.

  • I may be wrong, but I thought the movie was first? Didn't Kubrick (it was his movie, right?) ask Clarke for a different sci fi movie idea and 2001 was the result?

    I haven't read the book 2001 or 2010, but I read the other two. I thought the end of 3001 was pretty lame. I'm also annoyed by all the retrospective view of history crap in most sci fi. I'm pretty annoyed at everything today, though.

  • This would be the worst thing imaginable to DeBeers. The only reason diamonds are valuable is because they are "scarce", and the only reason they are "scarce" is because of DeBeers.

    Not news.

    Creating diamonds with pressurized methane is not a new idea either? Industrial quality diamonds may be produced with a pressure tank full of methane and a plasma torch. This has been known now for some time now.
  • The diamonds we value here on Earth are often cut and heated to remove impurities.

    I believe this method of producing diamonds is sometimes used to create cheap industrial quality diamonds for drills. The diamonds produced usually are not large enough to be of much interest for jewlery though.

  • Sorry, thanks for playing. Do we have some parting gifts for our contestant, Don Pardo?

    The force due to gravity is proportional to the products of the masses. So the force declines in proportion to the mass lost. But, because of F=ma, the accelleration due to gravity remains constant and thus so does the orbit.

    Of course, we could never get all that diamond in Jupiter, short of actually lighting the planet up and then scouring around for it, much as was done in the book. There's simply no easy way to pull it out of that immense gravity well. Hell, it mostly is the gravity well itself, being at the core.

    In other words, let's detonate Jupiter. It could be fun. :-)

  • You are correct, Arthur C. Clarke hypothoized that the center of Jupiter is a giant diamond in the book 2063. In the story, when Jupiter changed into a Sun, the diamond shot out of the middle of the core (!) and embedded itself in the new life planet of Europa. It's an excellent book, IMHO. If you think about it, it makes sense. What happens to that much carbon when compressed so much? And the hydrogen lake on top of the diamond field has to be impressive. `8r)

    What I find scary is how long ago did they have the article on how there could be life on Europa. True, it was thought to be true awhile ago, but they just found out about possible tides, meaning a liquid ocean. A liquid ocean could most definately mean life of some sort.

    But that's not the only mining technique we're familiar with, is it? Surely if we produced a significant enough explosion on the surface diamond chunks could be blown into orbit? I reckon you wouldn't even a proper bomb, just drop a lump of enriched uranium, and it will explode under those pressures & temperatures.

    Clarke used it in the book to predict the use of diamond in great quantity for industrial and space-explortaion purposes. In the book, of course, it was the Monolith & Co. who turned Jupiter into a star, thus expelling much of the diamond out into space.

  • By the time it becomes economical to reach uranus, or any of the outer planets, we will have the technology to produce diamonds from dirt (or anything else that contains carbon.) Nanotech would provide the means to easily reach the outer planets, and also provide the means to make diamond cheaply. So its really just a "gee wiz" scientific curiousity and doesn't have any bearing on the value of diamond or that we have found a large supply of the gem that could actually be useful. Anyway, just my 2 cents.
  • In the experiment, they used a laser to heat the Methane to about 3600 degrees F. Does it get that hot in the atmosphere of either neptune or uranus?

    as the StarTrek universe a place could exist
    where there's no need for rare minerals, gold,
    latinum, whatever, used _as a replacement for
    money_?

    I like this topic. Please rate me "Funny". :-)
  • Since most of the diamonds come out of Africa, and since Africa can be a scary place, (see flame throwers as car options) then they can do whatever they want there. If they were abundant everywhere on the planet, then of course no one would have a monopoly, but they aren't.
  • An interesting application for such a large quantity of diamonds would be their use as a construction material for several kinds of objects (like skeletons for particularly durable reserearch stations, ship hulls, or a space-to-planet cable that could serve as the basis for an inexpensive and highly efficent launching system). If buckyballs were present in any large quantities and could be isolatewd, then things might get really interesting.....
  • Actually, I stole the idea from the "mars" series by Kim Stanley Robinson. Sorry. Nothing else popped into my head at the time (lack of sleep). I think it is a really good idea, and merited inclusion despite its lack of originality, and that such materials would be the best choice for constructing space-to-planet-elevator cables and many other usefuls bits of space-stuff.
  • Instead of using a giant claw or what not, why not direct a giant asteroid to crash on neptune? Hopefully we might me able to get something flying out of there. Anyway, if there really was diamonds on neptune, we should have seen some of those on asteriod belts somewhere right?
  • If anyone did send diamond harvesting spaceships, it wouldn't be the US Government. It would be DeBeers.
  • I've never heard this name. I think proper names for Berkeley are:

    University of California, Berkeley
    University of California at Berkeley
    Berkeley
    UC Berkeley
    UC

    (these ones are almost exclusively used for sports)

    (the) University of California (Golden Bears)
    California
    Cal

    Stanfurd students call us Kal. I think they envy the fact that we can actually recieve C's and D's in classes. :)


  • Oh, YEEEEEEAAAAAAAAAAAH, like "a space-to-planet cable that could serve as the basis for an inexpensive and highly efficent launching system" is an original idea. :P Someone's read 3001, obviously. :D
