antimatter in cosmology

Antimatter is composed of particles that have the same mass as ordinary matter particles but opposite electric charge and other properties. In cosmology, antimatter is essential because, during the universe's early moments, matter and antimatter were created in nearly equal amounts. When they meet, they annihilate each other, releasing energy. Surprisingly, our universe is dominated by matter, with very little antimatter observed, leading scientists to explore why this imbalance exists—a key question related to the universe’s origin and evolution. The study of antimatter helps us understand fundamental symmetries in physics and the conditions of the early universe.
