Unified Field Theory: Composition of the Universe, Spacetime Motion, and the Invariance of the Speed of Light

This paper presents a new perspective on unified field theory, aiming to unify the four fundamental interactions in nature—gravity, electromagnetism, the weak nuclear force, and the strong nuclear force—by redefining the basic concepts of space, time, and motion. The author proposes that the universe consists solely of objects and the space surrounding them, and that all physical phenomena are descriptions of the motion of objects in space and the motion of space itself. Time is defined as the observer's perception of the movement of surrounding space, and the speed of light is viewed as an embodiment of the unification of space and time. By establishing a mathematical model of spiral motion in space, the paper explains the origin of physical concepts and reinterprets fundamental physical quantities such as mass, charge, and energy. The author also explores how the spiral motion of space leads to the unification of the four fundamental forces and discusses the essence of the invariance of the speed of light. This work aims to provide a new theoretical framework that deepens our understanding of the universe's fundamental laws and opens new avenues for the development of physics.
