For those science junkies that were disappointed when the Large Hadron Collider didn't manage to end the world by creating black holes, you'll be getting another chance in two years. The LHC will be down for the next two years so that it can undergo maintenance and upgrades to bring it back to peak efficiency.
The device will eventually make its way back online sometime in 2014. At that time, it's expected that the particle accelerator will be operating at up to 14 trillion electron-volts, double the energy it was running at in 2011. Part of the reason the LHC hasn't achieved higher energies yet is due to the helium gas explosion which damaged and delayed the project.
This maintenance period will be used to fix that damage, perform maintenance and upgrade the detectors, electronic shielding, and ventilation system.
