Europe's physics lab CERN in Switserland said Thursday they had begun tests in preparation for rebooting the world's biggest particle collider and trying to uncover new particles that could alter our understanding of the Universe and yesterday after they nearly doubled the energy levels possible in the collider, CERN scientists have their sights set on finding exotic new particles in a previously-inaccessible realm.
Although it seems unlikely we may wonder if the fireball has something to do with CERN.
