Ok, the big news is this: Researchers have gotten results that would indicate, if true, that something could travel faster than the speed of light. This is not supposed to be possible according to Einsteins theory of relativity because nothing should be able to travel faster than light in vacuum.
However, researchers have now measurements (15 thousand of them) that says that neutrinos (sub-atomic particles) travelled at a velocity 20 parts per million above the speed of light. They now invite other researchers to try and find out why these measurements turned out as they did. Was there some kind of systematic error, or do we need to redo much of what we understand about physics.
here is the press release from CERN about neutrinos traveling faster than the speed of light.
And a lot of people have already managed to post news about this news.
here is gizmag and XKCD two nerdy sites that i follow.
