The world's largest particle collider notched up a new record on Thursday as it escalated its quest to find fundamental matter and explore the origins of the Universe, CERN said.
At 00.38am on Thursday, the Large Hadron Collider (LHC) brought together two opposing beams of protons, each with an energy of four teraelectronvolts, the European Organisation for Nuclear Research (CERN) said in a press release.
"The collision energy of 8 TeV is a new world record, and increases the machine's discovery potential considerably," it said.
The LHC comprises a ring-shaped tunnel near Geneva, 27 kilometres long and up to 175 metres (570 feet) below ground.
Beams of protons are accelerated in opposed directions to nearly the speed of light.
