I think it's really important to be cautious here. http://xkcd.com/955/
I'm not saying this isn't awesome however. But the machines at CERN are some of the most complicated ever built by humans and there's a lot that could go wrong. There's a lot of physics that predicts events correctly built on Einstein.
However, Newton and Kepler both had theories that correctly predict events on Earth but aren't right when you look at things outside of the scale they had to work with when they were developing the theories. So there's that.
