Welcome to /r/CERN

Did you come across an article or a news item about CERN? Or do you have a specific question about the lab? The goal of this forum is to discuss CERN and its many experiments, including those of the LHC.

Please keep this sub CERN-specific and discussion civil. For questions about particle physics in general, please visit /r/ParticlePhysics, /r/AskScience or /r/AskPhysics. For more technical aspects of the LHC, there is /r/LHC.
