GENEVA—Expressing deep regret over the catastrophic incident that occurred within the Large Hadron Collider, officials from the European Organization for Nuclear Research, also known as CERN, held a press conference Monday to apologize for the destruction of five parallel universes in a recent experiment. “We are sorry to report that in conducting research involving high-powered proton-proton collisions, we inadvertently caused the implosion of five universes nearly identical to our own,” said CERN Director-General Fabiola Gianotti, adding that billions of people worldwide might have experienced momentary vertigo around 9:45 a.m. as a result of several of their alternate identities being wiped from existence. “I’d like to emphasize that there is no need to worry, as we were able to contain the damage before our own time stream disintegrated into oblivion like the others. Furthermore, in order to perform an investigation, the LHC will be shut down for the remainder of the afternoon.” At press time, a team of CERN researchers in a parallel universe was preparing to perform the exact same experiment.
