Symmetries and Antimatter

Scientists use symmetry both to solve problems and to search for new understandings of the world around us. In nuclear science the concept of symmetry plays a key role in gaining an understanding of the physical laws governing the behavior of matter. It provides a shortcut based on geometry for getting at some of Nature’s innermost secrets. Because the laws of physics are the same at any time (symmetry in time) and any location (symmetry in position) as another, the laws of conservation of energy and momentum apply.
