How Does the Weak Force Treat Matter and Antimatter Differently?

Why does the universe contain matter at all, and why did matter survive while antimatter almost completely disappeared? In this episode of The Sleeping Physicist, we explore matter-antimatter asymmetry, the weak force, CP violation, and the tiny imbalance that allowed stars, planets, and life to exist. Learn how antimatter was discovered, why the weak force can transform one particle into another, and how the Wu experiment revealed that nature distinguishes between left and right. We also explore neutral kaons, the Cronin and Fitch experiment, the CKM matrix, the CP-violating phase, the Sakharov conditions, and why the Standard Model still cannot fully explain the matter in our universe.
