Hadron Collider reboots after 2-year break
SCIENTISTS say they have successfully restarted the world's biggest particle collider after a two-year shutdown
THE Large Hadron Collider (LHC) has started delivering physics data as a result of what has been described as a "milestone" collision.
AFTER an almost two-year shutdown and several months of recommissioning, the world's largest particle accelerator is now providing collisions to all of its experiments at the unprecedented energy 13 tera-electronvolts (TeV).
