If you haven't heard about the LHC, you need to do some RESEARCH. Check Wikipedia links to get educated:
Basically, the thing has a possibility of creating mass...in theory. It is a MASSIVE scientific research effort, and whether it creates mass or not, something important is being proved or disproved.
So anyways, yeah... I could end the world or shed light on mass creation, anti-matter, and other dimensions, but the scientists working there (from CERN) have a pretty good sense of humor. Check out the video! :D
If we all die, I get your car.
