On the Fundamental Fallacy of the Spacetime Curvature Theory
Year: 2026
Type: preprint
Abstract: The theory of spacetime curvature and geodesic motion proposed by general relativity has become the mainstream paradigm for explaining gravitational orbital motion in modern physics. This theory attributes the curved orbital motion of celestial bodies to the deformation of spacetime caused by massive objects, such that objects move along geodesics defined by the inherent curvature of spacetime. This paper draws on three irrefutable objective physical phenomena and engineering examples including stationary celestial bodies, radially diving meteorites and disabled orbiting satellites to refute the physical reality of spacetime curvature at the fundamental logical level. This study demonstrates that spacetime curvature and natural geodesic orbits do not exist in the universe. All curved motion of celestial bodies arises from the superposition of the linear action of universal gravitation and the tangential inertia of objects. Spacetime curvature is not an objective law of the universe. It is merely a hypothetical model constructed after observing orbital phenomena to fit observational data, a cognitive error that substitutes appearances for essential physical mechanisms. Meanwhile, by analyzing concepts such as weak interaction and surface tension, this paper reveals a long standing defect in physics. Researchers often treat composite apparent effects produced by superposition of multiple forces or energy rearrangement as independent fundamental forces or spacetime properties, confusing mathematical fitting models with the true physical nature.
