全局本体时间模型

Special relativity defines the speed of light as a universal constant and describes high-speed observational effects using the Lorentz transformation. Within this framework, length contraction and time dilation are apparent measurement effects between different reference frames, and uniform motion does not alter the intrinsic physical state of objects. This paper proposes a global proper time model: the universe has a universal global proper time, and space possesses an objective benchmark without introducing an ether medium. The velocity of an object relative to the global benchmark changes the internal state of matter. Compressive deformation of particles along the direction of motion gradually builds up during acceleration, and static compressive stress remains constant in uniform motion. This model retains the postulate of constant light speed and reproduces measurement results consistent with special relativity at the observational level, yet its predictions about the intrinsic matter differ. A falsifiable prediction is presented: high-speed moving solids contain static compressive stress correlated with velocity, which may destroy material structure once exceeding the bonding threshold of chemical bonds. This paper proposes a decisive experiment based on the microscopic mechanical state inside moving objects, which differs from traditional experiments relying only on long-distance optical observation. The model simplifies spacetime concepts and alleviates the difficulty in understanding the temporal sequence arising from relativity.
