A Conceptual Model of Time Based on Relative Motion and Spatial Expansion
Year: 2025
Type: article
Abstract: This white paper presents a conceptual hypothesis that links the flow of time to the expansion of space. It proposes that relativistic time dilation effects — both special and gravitational — can be understood as different manifestations of a single principle: deviations in an object's relative motion with respect to the cosmological expansion, and variations in the length of geodesic paths in curved spacetime. Using a metaphor of a gramophone record, where the rotating surface represents expanding space, the needle represents the observer, and the music represents time, the model suggests that time flows normally when an object remains "at rest" with respect to the expansion. Any motion — in any direction — relative to this expansion reduces the rate of local time, while gravitational curvature alters the path length, further affecting the temporal flow. This hypothesis offers a unified conceptual framework for understanding both time dilation phenomena, while introducing a potentially novel perspective: that the very existence and flow of time is intrinsically tied to the dynamics of the universe's expansion. The paper does not provide mathematical proof but is intended as a speculative yet structured idea to inspire further investigation or theoretical exploration.
