Antimatter-Matter Symmetry

Antimatter-matter symmetry refers to the idea that for every type of matter particle, there's a corresponding antimatter particle with the same mass but opposite electric charge and other quantum properties. When matter and antimatter meet, they annihilate each other, releasing energy. This symmetry suggests that the universe's laws apply equally to both, implying that matter and antimatter should have been created in equal amounts during the Big Bang. Understanding this symmetry helps scientists explore why the universe is mostly matter today, despite the expectation of equal amounts of matter and antimatter being formed initially.
