Scientists have switched on the Large Hadron Collider (LHC), the device they hope will unravel some of the remaining mysteries of the universe.

At 9.30 am local time (8.30 am British Summer Time), 300 feet below the Franco-Swiss border near Geneva, the most powerful particle accelerator ever built became fully operational.
The switch-on saw the first stream of subatomic particles - known as Hadrons - circulating in the tunnel. The first collisions are expected in around 30 days.
