Poor Large Hadron Collider... perhaps what with all the mishaps that have befallen you, perhaps it is fate-- perhaps there is some weird time paradox that's keeping you running. Perhaps that bird that haphazardly dropped a piece of baguette in a piece of outdoor machinery and caused you to overheat was an agent of fate. Or perhaps, you're just the most complicated and sensitive machine ever created and there's a lot that can go wrong.

From Popular Science:

The bird dropped some bread on a section of outdoor machinery, eventually leading to significant over heating in parts of the accelerator. The LHC was not operational at the time of the incident, but the spike produced so much heat that had the beam been on, automatic failsafes would have shut down the machine.

This incident won't delay the reactivation of the facility later this month, but exposes yet another vulnerability of the what might be the most complex machine ever built. With freak accident after freak accident piling up over at CERN, the idea of time traveling particles returning from the future to prevent their own discovery is beginning to seem less and less far fetched.
