Yeah, so the LHC really, really can’t catch a break. Not only are bizarre electrical failures, Al Qaeda operatives and time travelers out to get them – PopSci reveals that even birds bearing French pastry are getting their licks in:
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.
