They’re only firing a laser through the entire ring system, to see if it can make a full circle. That is to say: testing to see if they built the thing right without holes. The particle smashing rape of reality as we know it - AKA you’re all fucking dead day - is scheduled for October 21st. The insane thing is, the LHC can be used for DOZENS of potential doomsday experiments. Smashing protons, creating antimatter, higher than 3D matter, artificial blackholes… so the test firing doesn’t have to kill us: there’s a waiting list of universal genocide at hand.
Oh… and get this: while building the LHC, they figured ways to make it even more powerful down the road. It’s the greatest theoretical death machine mankind has ever constructed! :twisted:
