The world’s largest and most powerful particle accelerator is set smash protons together on April 8 to search for invisible particles secretly powering our universe. Theories have suggested there are 17 different particle groups and the European Organization for Nuclear Research, better known as CERN, confirmed the existence of one using its Large Hadron Collider (LHC) in 2012. Now, the team has restarted the LHC with hopes of unraveling more mysteries of the universe - specifically dark matter. Scientists began preliminary tests by sending billions of protons around the LHC's ring of superconducting magnets to boost their energy and ensure...
