Large Hadron Collider not running properly? If you've read the docs and restarted it, check for a full moon. After noticing fewer particle collisions while on her shift, Pauline Gagnon reached out to a control room operator who casually explained that they adjust beam alignment during full moons. Yes, the tide-producing orbit of Earth's satellite tugs the LHC's inner workings ever so slightly askew. Though minute, the changes add up over the collider's 27km circumference and are picked up by monitoring equipment sensitive enough to measure elementary particles. However, Luna isn't the only thing that affects the accelerator -- the water level in Lake Geneva and passing high-speed rail trains also do the trick. Will your hand react differently to the LHC's beam under a Harvest Moon? Probably not. In any case, hit the source for the scientific details.
