The Expansion of Spacetime as the Basis for Light, Motion, and Time: A Thought Experiment in Theoretical Physics

This document explores a speculative hypothesis suggesting that the expansion of spacetime fundamentally governs light, motion, and the perception of time. The idea posits that light may not actively move but instead appears to do so as spacetime expands, transporting energy towards observers. It also reinterprets motion as a byproduct of spacetime expansion and proposes that time is an emergent property of this process. The hypothesis aims to provoke discussion and inspire further exploration in cosmology and quantum mechanics. This work is shared as a thought experiment for critique and potential development by the scientific community.
