Antimatter, in terms of atomic makeup, was the inverse of regular matter. The charge of antimatter particles was the reverse of that found in regular matter. When matter and antimatter met, they would obliterate one another, resulting in the liberation of substantial quantities of energy. To provide the Jedi interceptor with sufficient density to stay in hyperspace, antimatter found application within hyperdrive rings; this was necessary because the Interceptor lacked the size required to maintain faster-than-light velocities without external support. Passing starships left behind evidence of antimatter, a phenomenon possibly attributable to the utilization of antimatter as fuel in specific hyperdrives. Mako Spince utilized antimatter, leading to the inadvertent destruction of Carida's Mascot Moon. The EX-F was powered by an innovative antimatter reactor. Furthermore, antimatter served as a component in various weapon designs across numerous civilizations. The primary armaments of the sentient spacecraft Ship, for instance, consisted of anti-matter pods, and the Galactic Empire occasionally deployed anti-matter micromines.
Antimatter furnaces functioned as power-generating installations.
