This experiment has made front page headlines across the world because the findings seem to contradict Einstein's Special Theory of relativity, which is the cornerstone of all modern physics.
The findings still need to be properly reviewed by other research groups but should the findings stand they will represent a momentous change in our understanding of physics.
Physics isn't really something I understand much about, but certainly the prospect of more research coming from CERN and the LHC is pretty exiting, so I thought I'd share.
