Massive CERN Photo. The unit to the left is the massive chamber (one of several) weighing between 7,000 and 12,500 ton impact chamber in which two protons collide emitting it products outward to be identified and analyzed by the outer layers of the collider. So that left unit fits into the right field unit when the proton collision occurs and all those layers of the field each identify different particle and energy types.

In clear, nontechnical language, string theorist Brian Greene explains how our understanding of the universe has evolved from Einstein's notions of gravity and space-time to superstring theory, where minuscule strands of energy vibrating in 11 dimensions create every particle and force in the universe. (This mind-bending theory has been testing at the Large Hadron Collider in Geneva).
