The Hypothesis of Variable Inertia: On the Intrinsic and Space–Time Dependent Nature of Matter

This paper proposes the Hypothesis of Variable Inertia, suggesting that the inertia of matter may vary with its position in space–time, reflecting the intrinsic nature of mass and its interaction with the structure of the universe. It discusses conceptual and natural evidence, proposes a theoretical formulation, and offers possible experimental verification under different gravitational conditions.
