Harder-Than-Diamond Natural Carbon Crystals Found

HikingStick tips a piece from the science desk at MSNBC.com about a new, naturally occurring form of carbon found in a meteorite fragment. "Researchers were polishing a slice of the carbon-rich Havero meteorite that fell to Earth in Finland in 1971. When they then studied the polished surface they discovered carbon-loaded spots that were raised well above the rest of the surface — suggesting that these areas were harder than the diamonds used in the polishing paste... [G]raphite layers were shocked and heated enough to create bonds between the layers — which is exactly how humans manufacture diamonds... [The research] team took the next step and put the diamond-resistant crystals under the scrutiny of some very rigorous mineralogical analyzing instruments to learn how its atoms are lined up. That allowed them to confirm that they had, indeed, found a new 'phase' or polymorph of crystalline carbon as well as a type of diamond that had been predicted to exist decades ago, but had never been found in nature until now."

    You must have limited knowledge of metal then.... Fast != hard

    I think you mean speed metal.

    Well, I think it's a reference to "The Lazarus Experiment," where the Doctor uses his sonic screwdriver to turn the organ up to 11 so that he can blast Lazarus out of the bell tower. So there.
