Exact Calculation of the Universal Global Spin Period and Deviation Analysis of Mainstream Models Based on Real-Imaginary Binary Field Theory

Abstract To address the Hubble tension, Szapudi et al. proposed the rotating universe hypothesis in 2025 and set an upper-limit estimate of approximately 500 billion years for the universal spin period. Grounded in the fundamental postulates of Real-Imaginary Binary Field Theory, this paper adopts macroscopic vacuum lattices, intrinsic field damping, and the conjugate golden decay law as its core framework. Taking the Jupiter source weight of 49.9 as the calibration benchmark for local fields, it rigorously derives the universal global spin period from first principles. After accounting for intrinsic field damping dissipation, lattice coupling attenuation, and separation of global coherent signals, the complete current spin period of the universe is calculated to be roughly 7,830.95 trillion years, around three orders of magnitude larger than results from mainstream simplified models. This paper further introduces the concept of the Cosmic Dao Plane, demonstrating that the axisymmetric spacetime structure arising from global lattice spin inherently contains a benchmark symmetry plane perpendicular to the principal spin axis. Within this framework, two parity-violation phenomena—parity non-conservation in microscopic weak interactions and statistical asymmetry in macroscopic galaxy rotation directions—can be uniformly interpreted. Both are observational manifestations of the intrinsic chiral bias of vacuum lattices across different scales. This paper systematically analyzes the root causes of deviations between the two categories of models and presents quantitative predictions for corresponding observable tests, offering theoretical references for validation via high-precision astronomical observations in the future.
