If you want to know when not to expect annihilation of the earth following a second-big-bang in the Large Hadron Collider, I’m afraid the best I can offer you is a link to their press site.

They are being very coy about exactly when things will happen.

In case you missed it, Brian Cox recently let the cat out of the bag: apparently, the LHC will, indeed, create a black hole and destroy the planet. Oh well, small price to pay…
In any case, they are probably right to not give a firm timetable. If they want it to work, they need to focus on the equipment, not the PR; something they seem to be doing, going by the statement that ‘No press will be invited for these events’.
