Single Idea 19483

[filed under theme 7. Existence / A. Nature of Existence / 5. Reason for Existence ]

Full Idea

The phenomenon of charge-parity (CP) violation says that under certain circumstances antiparticles decay at different rates from their matter counterpart. ...This might explain matter's dominance in the universe, but the effect is too small.

Gist of Idea

CP violation shows a decay imbalance in matter and antimatter, leading to matter's dominance

A Reaction

Physicists are currently studying CP violations, hoping to explain why there is any matter in the universe. This will not, I presume, explain why matter and antimatter arrived in the first place.
