'Not in Our Stars: Large Hadron Collider Incident Results in Multi-Month Shutdown

OK, it wasn't a black hole, or at least no one is saying, but Something Happened to require a shut down of the Large Hadron Collider at CERN in Geneva, Switzerland.

According to Time: Although a final evaluation is yet to be completed, scientists believe the fault caused the machine to lose the near absolute-zero temperature it must maintain to operate. For now, however, repair work can't begin because the machine is still too cold; it will take about a month to warm up the area to a temperature at which replacement parts can be inserted. It will take another month to cool it back down, and given that CERN has pledged not to run its giant machine — which requires as much power as the entire city of Geneva — during winter months when Europe's energy needs are highest, Friday's breakdown could delay the actual smashing of atoms until early next year.

CERN spokesman James Gillies called the fault a "teething problem" and said that previous accelerators that used superconductivity — i.e., low temperatures that allow metals to conduct electricity without resistance — also faced early problems before "running pretty smoothly after they were sorted out." Even so, "it's certainly a disappointment," he added.

When it is fully operational, the $6 billion LHC will send beams of protons careening around a 17-mile underground ring, crash them into one another to re-create the immediate aftereffects of the Big Bang, and then monitor the debris in the hopes of learning more about the origins and workings of the universe.
