The Eternal Relativity: Note 22 - Time as the 5th Fundamental Force

We propose that Time is not a background parameter but the 5th fundamental force of nature. In 4D-Time theory, the universe is a manifold T(T¹,T²,T³,T⁰). Three dimensions constitute differential flow. The fourth, T⁰: Nothingness, is the absolute singularity and source. We derive the coupling constant of time-flow κₜ = 2.076 × 10⁻⁴³ s⁴ kg⁻¹ m⁻³, and show that gravity, electromagnetism, strong, and weak forces are all symmetry-broken modes of a single time-flow field. All motion, mass, and spacetime curvature emerge from gradients and knots in this flow. We provide a falsifiable prediction: Time-Flow Radiation detectable as 32.9 PHz phase noise in optical clocks.
