回顾光速的测量历程、仔细分析光速测量试验可以发现,在测量过程中存在光子的“波函数坍缩和重新生成”的过程,人们没有考虑这个关键性的要点。波函数的坍缩和重建是量子理论中的重要内容,如果考虑了该要点,就一定会发现光速不变还有更加深刻的内涵,这将彻底动摇建立相对论的理论基础。光子(或电磁波)波函数坍缩和重新生成的过程还是形成粒子的充要条件,也是粒子存在动能、惯性、惯性质量的根本原因。 A review of the history of measuring the speed of light and a careful analysis of experiments to measure it reveal that there is a process of "collapse and regeneration of photon wavefunctions" during measurement, which has been overlooked. The collapse and regeneration of wavefunctions are crucial in quantum theory. If this aspect is considered, it becomes evident that the constancy of the speed of light has deeper implications, which could fundamentally shake the theoretical foundation of relativity. The process of collapse and regeneration of photon (or electromagnetic wave) wavefunctions is also a necessary and sufficient condition for the formation of particles and the fundamental reason for particles to possess kinetic energy, inertia, and inertial mass.
