So because I'm a total dork, I just e-mailed my DH at work and asked if he knew anything about this (he generally is up on the "science" news and works in technology) and whether I should be prepared for immenent black hole chaos.

Actually, I just asked if it was something to be concerned about. Obviously he is NOT an expert, but here was his short answer:
The collider they built is simulating things which occur on an hourly
basis in our own upper atmosphere, when hypercharged particles collide
with our atmosphere.
In short, no, its nothing to worry about.
