| contents | In cosmology, the Gurzadyan's theorem identifies the most general force law consistent with the finding of Newton's first shell theorem -- that a spherical symmetric mass exerts the same gravitational force as a point mass at its center. This theorem has found important applications in cosmological modeling, particularly in the context of MoND (Modified Newtonian Dynamics), which has recently gained renewed attention as a potential alternative to dark matter. The derivation by Gurzadyan is written in an extremely concise and dense style, making it difficult to follow. Recent proofs of the theorem based on power-series methods offer valuable perspectives, though they differ from the original derivation, which is based on perturbation analysis. Our note aims to clarify the underlying logic in a pedagogical way -- accessible to advanced high school or undergraduate students -- while preserving conceptual clarity and mathematical elegance of his insight. |
