The universe's greatest mystery: “The vanished antimatter.” Immediately after the birth of the universe (the Big Bang), matter and antimatter are thought to have been created in exactly equal numbers. Yet surveying the universe today reveals almost no antimatter in nature, and our Earth and stars are made only of matter. The mystery of “why only antimatter disappeared while only matter remained” is thought to relate to the physical phenomenon of “CP symmetry violation,” but has not yet been fully explained.
宇宙最大の謎「消えた反物質」宇宙誕生(ビッグバン)の直後には、物質と反物質がまったく同数生まれたと考えられています。しかし、現在の宇宙を見渡しても自然界に反物質はほとんど存在せず、私たちの地球や星は物質だけでできています。この「なぜ反物質だけが消え去り、物質だけが残ったのか」という謎は、「CP対称性の破れ」という物理学の現象が関係しているとされていますが、いまだ完全には解明されていません
