article_snippet.sent: The purpose of the lengthy project is to recreate the conditions that existed moments after the "Big Bang" -- the scientific theory said to explain the creation of the universe.
article_snippet.sent: By replicating the energy density and temperature, scientists hope to uncover how the universe evolved.
article_snippet.sent: Our current, limited, knowledge is based on what's called The Standard Model of particle physics.  
article_snippet.sent: But Our know that The Standard Model of particle physics is not complete," Dr. Mike Lamont, operations group leader at the LHC, told CNN in March.
article_snippet.sent: The burning questions that remain include the origin of mass and why some particles are very heavy, while others have no mass at all; a unified description of all the fundamental forces such as gravity; and uncovering dark matter and dark energy, since visible matter accounts for only 4 percent of the universe.
article_snippet.sent: the LHC could also question the idea that the universe is only made of matter, despite the theory that antimatter must have been produced in the same amounts at the time of the Big Bang.
article_snippet.sent: CERN says the energies achievable by the LHC have only ever been found in nature.
article_snippet.sent: Scientists and physics enthusiasts will be waiting with bated breath as the LHC ventures into the great unknown.
