The Proper Circle Theory of Everything

This work introduces a novel paradigm for unification by positing a fundamentally angular, rather than linear, nature for proper time (τ = R·θ). Our theory, "Cyclic Time Covariance," directly resolves the conceptual conflict between the dynamic time of General Relativity and the parametric time of Quantum Mechanics, providing a geometric origin for quantum phase. It offers a more economical alternative to extra-dimensional models, unifying gravity and gauge forces through the geometry of an internal temporal fiber. Its primary innovation lies in its concrete falsifiability, advancing testable predictions for gravitational waves, particle physics, and cosmology. This Letter proposes a fundamental reconceptualization of time, offering an elegant solution to the long-standing time problem in quantum gravity. Unlike prevailing unification models, our theory is directly testable. It predicts concrete phenomena: a new scalar boson (the "chronon"), unique scalar polarization modes in gravitational waves for LISA, and signatures of cosmic variance in fundamental constants. The compelling simplicity of its postulate and its profound, falsifiable implications for gravitation, particle physics, and cosmology warrant the rapid dissemination and broad scrutiny that PRL provides.
