Parity Violation: Why The Weak Force Only Likes Left-Handed Particles | Nobel Winner Explains

Описание: Nobel laureate Sir Roger Penrose reveals physics' most overlooked mystery: The universe has a handedness. The weak nuclear force violates parity symmetry—it only couples to left-handed electrons, never right-handed. All neutrinos are left-handed (right-handed ones have never been detected). This asymmetry enables CP violation, which explains matter-antimatter imbalance, which is why you exist. But WHY is the universe left-handed? Could it have been right-handed? Discover the shocking 1956 Wu experiment that shattered parity symmetry, why Standard Model treats handedness as a "free parameter" with no explanation, how Penrose's twistor theory suggests chirality might be geometric necessity (spinors are inherently handed), why anthropic principle is philosophically lazy, and what this tells us about causality's hidden structure. The universe chose a side. And nobody knows why.
