CERN traps antimatter for 1,000 seconds By aimee whitcroft • 09/06/2011 • 1 Related antimatter CERN One Response to “CERN traps antimatter for 1,000 seconds” cool. A co-worker asked me to cover it when the same group trapped anti-hydrogen for a couple hundred milliseconds earlier in the year. Didn’t get around to it. This might spur me on.
