Antimatter [Astro*Index]

Matter whose mass and spin are identical to that of ordinary matter but oppositely charged: antiprotons instead of protons, positrons instead of electrons, and antineutrons instead of neutrons. Antimatter is of interest to theorists on the origins of the universe. Of interest is why little of it has been found naturally (some has been produced by experiment).
