LHC - The Large Hadron Collider (thanks CombatMedic) - This particle accelerator will be the largest device of its kind when it begins operating in 2008. It will also have a chance of destroying our planet or the entire universe through the creation of a black hole, strange matter that is more stable than ordinary matter, magnetic monopoles that could catalyze proton decay, or by triggering a transition into a different quantum mechanical vacuum.
The chance that any of that will happen is very small, so they're willing to risk it.
Cons: causes bad nightmares. I used to have to eat beef until I passed out to have these kind of terrors, but this machine does it for me every time I fall asleep inside it.
Sorry about the blurry photo. I was lunging at my phone, yelling at it to take a clear picture. It's the only image of me that exists. I'd take another picture for you, but I'm in the middle of a rigorous trampoline session.
