Abstract
Symmetry principles play a central role in modern theoretical physics, governing the very structure of mutual interactions and the fundamental organization of spacetime. Among discrete symmetries, spatial parity as well as the chirality determine whether the physical laws distinguish between left and right orientations of fields and particles. While typically, parity symmetry is preserved in the classical gravitational theory as formulated by Albert Einstein, it is maximally violated in the weak interaction, a phenomenon experimentally demonstrated by Chien-Shiung Wu following the theoretical work of Tsung-Dao Lee and Chen-Ning Yang. This contrast raises a fundamental question: whether spacetime geometry itself possesses intrinsic chirality or whether asymmetry arises solely from matter interactions.
