Earth's Core Far Hotter Than Thought

Posted by timothy on from the might-as-well-be-walking-on-the-earth dept.

hessian writes "New measurements suggest the Earth's inner core is far hotter than prior experiments suggested, putting it at 6,000C — as hot as the Sun's surface. The solid iron core is actually crystalline, surrounded by liquid. But the temperature at which that crystal can form had been a subject of long-running debate. Experiments outlined in Science used X-rays to probe tiny samples of iron at extraordinary pressures to examine how the iron crystals form and melt."

    So a "racist joke" has to automatically be about "black people?" Who's the racist now?

    Historically blacks have in fact been the most notoriously discriminated against race, so it's a good example.
