Well the public test runs of the LHC keep getting put back, with the new turn on date being June this year, but I wouldn't be too concerned, if you honestly think that CERN they would turn the thing on with thousands of million people waiting with baited breath,waiting to see what happens then you would be an idiot, as if they wouldn't have already run it in secret to make sure it works.

If everyone cared and nobody cried
If everyone loved and nobody lied
If everyone shared and swallowed their pride
Then we'd see the day when nobody died....Chad Kroeger
