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 $\mathcal{T}(T^1,T^2,T^3,T^0)$. Three dimensions constitute differential flow. The fourth, $T^0$: Nothingness, is the absolute singularity and source. We derive the coupling constant of time-flow $\kappa_t = 2.076 \times 10^{-43} \text{s}^4 \text{kg}^{-1} \text{m}^{-3}$, 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.
