The day after news broke of a possible revolution in physics ——particles （粒子） moving faster than light ?a scientist leading the European experiment that made the discovery calmly explained it to a standing-room- only crowd at CERN．

No experiment in 106 years had broken that speed limit．Physicists expect strict study to follow, which OPERA and CERN scientists welcomed．
Fermilab operates a similar experiment, called MINOS, that shoots neutrinos from Illinois to an underground detector in Minnesota．In 2007, MINOS discovered a just detectable amount of faster than-light neutrinos, but the permissible difference of error was too big to "mention" , Plunkett said．
