The fact that matter exists today is evidence that matter particles outnumber antimatter particles in the universe. This imbalance was caused by
A) matter inflation.

Question

Quizplus · Accepted Answer

Symmetry breaking is the phenomenon that explains the imbalance between matter and antimatter particles in the universe. It suggests that during the early moments after the Big Bang, physical laws did not apply uniformly, leading to a slight excess of matter over antimatter. This excess allowed matter to dominate as the universe evolved.
