The Higgs boson "rumor is based on what appears to be a leaked internal note from physicists at the Large Hadron Collider (LHC), a 17-mile-long particle accelerator near Geneva, Switzerland. It's not entirely clear at this point if the memo is authentic... The buzz started when an anonymous commenter recently posted an abstract of the note on Columbia University mathematician Peter Woit's blog, Not Even Wrong."
This could be a flat-out hoax or a statistical anomaly or... confirmation of the particle that bestows mass on all the other particles." Link to Original Source
