Structural Differentiation Time (SDT) v1.0: Time as Irreversible Structural Differentiation

This repository presents Structural Differentiation Time (SDT) v1. 0, a minimal and self-contained structural definition of time. In standard formulations, time is treated as an external parameter governing physical evolution. In SDT, time is instead defined as the irreversible ordering of structural differentiation. The framework is summarized by a single minimal expression: τ (D) = 1 − exp (−λD) This formulation implies that time does not independently flow, but emerges as the accumulated record of irreversible structural change. Core claim: Time is not a parameter. It is irreversible structural ordering. A key implication of SDT is that the arrow of time is not imposed externally, but arises from the intrinsic positivity of structural accumulation: dτ/dD > 0 Structural time also exhibits asymptotic behavior: lim₃→∞ τ (D) = 1 This indicates that time approaches a limiting structure but never reaches complete closure, reflecting irreversible accumulation without full completion. SDT provides a foundational temporal definition layer linking multiple structural frameworks: - SDQ interprets time within quantum structure- SDT defines time itself as structural ordering- SDC extends structural time into cosmological evolution Thus, quantum time, observational time, and cosmological time become structurally unified. The figure included in this repository is not an arbitrary visualization, but a direct conceptual representation of the defining structure of time and its relation to SDQ and SDC. If validated, this framework implies a shift from time-based physics to structure-based physics, where temporal behavior is treated as an emergent observable rather than a primitive variable.
