Question

Why does the existence of something instead of nothing in the universe involve a tiny, asymmetrical surplus of matter over antimatter, leading to the presence of ordinary matter and the conditions necessary for our existence?

Answer 1

The existence of a surplus of matter over antimatter in the universe is essential for the conditions necessary for our existence.

Step-by-step explanation:

The existence of a surplus of matter over antimatter in the universe is crucial for the presence of ordinary matter and the conditions necessary for our existence. If matter and antimatter were initially present in exactly equal proportions, they would have annihilated each other, leaving only pure energy. However, a small asymmetry in the decay of neutral K-mesons and a fundamental asymmetry in the basic forces resulted in a slightly larger amount of matter than antimatter in the early universe. This surplus of matter allowed matter to form stars, galaxies, and eventually life.
