Scientists making discoveries that defy the laws of physics seems to be something of a theme this month. Now the eggheads at CERN say they’ve observed subatomic particles moving faster than the speed of light, which might theoretically allow us to travel back in time. Eryn Brown and Amina Khan report for the LA Times:

Albert Einstein had the idea. A century of observations have backed it up. It’s one of the cornerstones of physics: Nothing travels faster than the speed of light.
But now a team of experimental physicists at the European Organization for Nuclear Research, known as CERN, says that one exotic particle possibly can.
The scientists reached their conclusion after sending streams of tiny, subatomic particles called neutrinos hurtling from an accelerator at CERN outside Geneva to a detector at the Gran Sasso National Laboratory in Italy, about 450 miles away.
The neutrinos seemed to get there too soon — 60 nanoseconds too soon, give or take — than they should if they’d been traveling at the speed of light.
