Emergence of the Lorentzian Metric Signature in Temporal Flow Physics
Emergence of the Lorentzian Metric Signature in Temporal Flow Physics John Gavel Abstract: In Temporal Flow Physics (TFP), time is fundamental as a quantized one-dimensional flow, and space emerges from the relational structure of fluctuations in this flow. We rigorously prove that the Lorentzian signature of the emergent spacetime metric arises naturally from the causal and statistical properties of temporal flow fluctuations, rather than being imposed as a postulate. This section formalizes the assumptions, constructs the emergent metric tensor from flow correlations, and demonstrates how causality enforces the Lorentzian signature. 1. Introduction and Setup We consider a fundamental scalar flow field F : M → R , F = F ( x ) , x ∈ M F: \mathcal{M} \to \mathbb{R}, \quad F = F(x), \quad x \in \mathcal{M} where M \mathcal{M} is an emergent 4-dimensional manifold with coordinates x μ = ( x 0 , x 1 , x 2 , x 3 ) , μ = 0 , 1 , 2 , 3 , x^\mu = (x^0, x^1, x^2, x^3), \quad \mu=0,1...
