not really, i learned that because apparently many believe that CERN picked that name because they are pantheists, and then some people got photographed performing some ritual on the campus involving goat horns or something, i forget
also this weird romanian psy/ambiant artist made this track: https://e-mantra.bandcamp.com/track/cernunnos
which also put the word into my memory
it's a pretty bouncy dance tune also, classic psytrance
