How to Tell Matter From Antimatter | CP Violation & The Ozma Problem

The video explores the concept of mirror symmetry in physics, highlighting how most phenomena appear the same in a mirror. It introduces the Ozma problem, which is the challenge of defining left and right without shared reference points, especially when communicating with aliens. The weak nuclear force, unlike other forces, does not behave symmetrically, allowing for the identification of left-handed and right-handed particles. This asymmetry is crucial for distinguishing matter from antimatter. The video further discusses how kaons, a type of subatomic particle, can help solve the Ozma problem by providing a consistent way to define left and right, even when considering antimatter.
