The Speed of Light as a Boundary of Spatial Time: A Conceptual Overview

This working paper provides a concise conceptual overview of an interpretative idea within the Specular Field Theory (SFT): the speed of light as a geometric boundary of the spatial time associated with the physical sheet. The document outlines the dual‑sheet structure introduced by the SFT and presents the notion of the speed of light as the limit at which the directional temporal coordinate reaches its structural boundary. The overview is intentionally minimal and does not include the mathematical formulation, which is reserved for ongoing collaborative development. Its purpose is to outline a direction of research, establish conceptual priority, and invite interest from groups exploring geometric approaches to time, quantum dynamics, and related theoretical frameworks
