Time Field Theory (TFT) Popular Science Introduction: The Nature of Spacetime and Gravity from the Perspective of Time Scale Self-Consistency

This paper systematically introduces the core logic and physical image of Time Field Theory (TFT) in a popular and rigorous language. TFT does not overturn the observational conclusions of relativity, but reconstructs the physical nature of spacetime and gravity starting from the **ontological status of time scale**. This paper clarifies: the unique self-referential property of time as the measurement benchmark itself; how the self-consistency constraint of the time field naturally derives nonlinear gravitational effects; and how TFT can explain all classical relativistic observational phenomena with a unified mathematical form in the framework of flat Euclidean space. Adhering to the principle that "physical logic is the original text, and mathematics is merely translation", this paper reveals the common origin of gravity, mass, energy, and conservation laws through intuitive physical images. ## About This WorkThis is the official popular science introduction to the Time Field Theory (TFT) series. It is intended for physicists, students of physics, and scientifically literate general readers who wish to understand the core ideas of TFT without advanced mathematical prerequisites. This work is based on the complete axiomatic system established in the TFT technical paper series. All conclusions are strictly derived from first principles without additional ad hoc assumptions.
