(Newser) – For two decades, scientists have thought the Earth's solid core was a balmy 9,000 degrees Fahrenheit or so, based on the temperature at which iron crystallizes when under high pressure. But new research using X-rays to examine iron under huge amounts of pressure indicate the real temperature of the core is closer to 10,800 degrees—about the same as the surface of the sun, reports the BBC. The findings from the French research team are outlined in Science.

The Earth's Core is as hot as the surface of the Sun. Earth's Core is 4,500 miles down....listen to what I am saying, put your thinking hats on. We have planets, Mars, Jupiter, Saturn Neptune and Uranus to name a few. These planets are Millions of miles away from the Sun and still glow in the night from the shining light of the Sun. Look, 4,500 miles does not come close or should even be of worthy mention when it comes to distances that are almost light years away. If the Earth's Core is as bright and hot as the Sun, why doesn't it shine through to the surface. If it was as hot as the Sun, which is 93,000,000 miles away and our Core 4,500 miles away. The 11,000 degree Core heat would have blown us up to bits. For 20 years it was at 9,000 degrees. Personally, I cannot reconcile with the scientists point of view. Where had the 2,000 degrees been for 20 years. Awe Schucks....beam me up Scotty. 1942

That idiot Al Gore said in a speech that it was millions of degrees below the crust. I guess professor Gore was a little off like most of the crap that comes out of his mouth.
