A small mammal has sabotaged the world’s most powerful scientific instrument.
The Large Hadron Collider, a 17-mile superconducting machine designed to smash protons together at close to the speed of light, went offline overnight. Engineers investigating the mishap found the charred remains of a furry creature near a gnawed-through power cable.
“We had electrical problems, and we are pretty sure this was caused by a small animal,” says Arnaud Marsollier, head of press for CERN, the organization that runs the $7 billion particle collider in Switzerland. Although they had not conducted a thorough analysis of the remains, Marsollier says they believe the creature was “a weasel, probably.” (Update: An official briefing document from CERN indicates the creature may have been a marten.)
The shutdown comes as the LHC was preparing to collect new data on the Higgs Boson, a fundamental particle it discovered in 2012. The Higgs is believed to endow other particles with mass, and it is considered to be a cornerstone of the modern theory of particle physics.
Researchers have seen some hints in recent data that other, yet-undiscovered particles might also be generated inside the LHC. If those other particles exist, they could revolutionize researcher’s understanding of everything from the laws of gravity, to quantum mechanics.
