Some of the profound questions about elementary particles and forces and the universe will be described; questions that might be answered as the Large Hadron Collider at CERN turns on this year. For example: What gives mass to elementary particles? Do all the forces between particles arise from a single basic force? What is the dark matter that makes up one fourth of the universe and is critical to the formation of galaxies? One speculative theory that seeks to address some of these questions is called supersymmetry. It uses quantum variables to describe space and time and suggests that every known particle has a yet-undiscovered superpartner particle. These new particles may soon be discovered at the Large Hadron Collider.
