The CERN Large Hadron Colider (LHC) is getting ready to start up again after a malfunction caused them to shut down for a year for repairs. The reactor has also been delayed because one of the scientists had terrorist ties and most recently a piece of bread was dropped into some machinery. This has given rise to the theory that the "god particle" or future scientists are reaching back through time to try and stop the LHC from coming online.
The Higgs Bosun particle has been dubbed the "god particle" since proving its existence would go a long way toward explaining the conditions at the beginning of our universe.
