CERN announced that the Large Hadron Collider (LHC) successfully tested particle collisions at the highest energy level possible after its updates, 13 TeV (13 trillion electron volts). After the restart of the enormous particle accelerator took place at Easter, the energy levels were gradually increased and in Wednesday’s late night the collisions reached the maximum energy.
