Stars, galaxies, and everything in the universe, including our own bodies, are comprised of so-called regular matter. Regular matter includes atoms and molecules, which are made up of tiny particles, such as electrons, protons, and neutrons. These particles dominate our universe, vastly outnumbering their lesser-known counterparts: antimatter particles. First experimentally discovered in 1932 by the late Nobel laureate and longtime Caltech professor Carl Anderson, antimatter particles have the opposite charges to their matter counterparts. The antimatter particle to the negatively charged electron, for example, is the positively charged positron.
