Question

Quizplus · Accepted Answer

Laboratory research has shown that when matter and antimatter come into contact, they annihilate each other, releasing a significant amount of energy. This suggests that if matter and antimatter were created in equal amounts in the universe's early stages, they would have quickly annihilated each other, leaving only radiation behind. However, we see mostly matter in the universe today, indicating that there was slightly more matter than antimatter. Therefore, the excess matter survived and formed everything we see today.
