As part of a clean up process, the folks at the Large Hadron Collider (LHC) - the largest single machine on planet Earth - are in the process of disconnecting old cabling to make room for the new. Around 9,000 cables, which is a lot - particularity as some of them are long cables.
EngadgetThe crew has already disconnected 2,700 of the cables, and expects to remove all of them in 2017. CERN shouldn't have any problems with the LHC shutdown scheduled for 2019, in other words. And hopefully, this won't be necessary again. The gigantic amount of clutter stems from a "not-so-good habit" of leaving old cables around, which suggests that engineers will be much smarter about cleaning up in the future.
