The LHC has problems of it's own

The Large Hadron Collider (LHC) is the biggest particle accelerator in the world. On 9/19/08 the magnets developed a spot of resistance and started to heat up. Their intended temperature was 2 C above absolute zero (0 K, -273.15 C, -459.67 F). As the heat grew the magnets vaporized. Later, when people went in to fix the LHC they found out that a spark might have punctured a cushion of cooled Helium that was keeping the magnets cool. Dr. Gillies has an easy word for all of us,"It's a mess." The incident wasn't tragic. It would have had to shut down in 2 months to save electricity. I am not saying that you shouldn't worry. To fix it, 53 superconducting magnets would have to be brought up 300 feet, fixed or replaced, brought back down 300 feet and after THAT they would have to be cooled to 2 Kelvin! Source: NYTimes
