Spacetime Waves and Physical Pictures Based on the Bichiral Quaternion Framework

This work introduces the concept of spacetime waves within the bichiral quaternion framework. Within this framework, a class of spacetime waves based on unit quaternions is constructed, from which a corresponding point-particle structure is obtained. The connection between this structure and the mathematical structure of SU(2) is then discussed. Furthermore, from the perspective of intuitive physical pictures, preliminary discussions are presented on several fundamental concepts in physics, including electric charge, spin, magnetic moment, the Pauli exclusion principle, parity violation, and the Big Bang.
