Innovation Points: 1. The differential element dx is redefined, and the basic logic and physical meaning of calculus are fundamentally reconstructed. 2. The cosmic spatial quantity limit C is defined, the distribution factor k is defined. 3. Clear distinction: the cosmic speed limit u is defined, the speed of light c is re-defined. 4. The four-dimensional cosmic model is described based on the unified spacetime framework. 5. A new unified field theory is constructed, which can explain both quantum mechanics and relativity.
