Logical Canvas and Mathematical Container: The Concept of Space in Time Field Theory (TFT)

This paper systematically demonstrates the concept of space in Time Field Theory (TFT), clarifying its essential difference from Newtonian absolute space and general relativistic spacetime. TFT's space is not a physical entity, not a geometric structure, not a dynamical participant, but a mathematical blank container of the measurement system. It is merely a set of coordinate labels, the logical background for the distribution of the time field γ, and the a priori premise that allows the concept of "position" to exist.

This paper rigorously proves that the flatness of space is not a physical hypothesis but the default state of nothingness; the time field γ is the only physical measurement benchmark of the universe; space does not participate in any interactions, and all dynamical evolution is uniquely borne by the time field. Most importantly, TFT does not argue about what the "noumenon" of "cosmic space" looks like—it only describes the logical appearance of "measurement system space", which is flat, blank, and non-dynamical, as this is the most parsimonious logical background required for the self-consistent operation of measurement benchmarks.

This ontological position is a natural corollary of TFT's metrology and the most fundamental ontological boundary between TFT and all traditional physical theories. This paper is the space philosophy volume of the TFT metrology series, and together with papers such as On the Possibility of Measurement and Spacetime Flux Conservation as the Meta-Conservation Law, constitutes the complete philosophical foundation of TFT.
