That's right ladies and gentlemen, the time of particle physics glory (or world destruction through mini-black holes) is rapidly coming upon us. If you're not really familiar with the Large Hadron Collider, check out their website. The long and short of it is that it is the most complex machine ever made by man (maybe the biggest too) and it's designed to find some of the smallest and most elusive particles ever theorized. Right now we don't really understand a lot of things, especially gravity, and the LHC may be able to help with that.
If you already know a bit about it, here's a fun countdown clock to let you know when the first particle stream cuts loose.
