This repository contains the final, version-controlled Jupyter notebooks supporting the article: “Gravity as an Entropic Gradient Field (Φₛ)”Renato Henriques (2026). The notebooks implement numerical simulations, analytical validations, and predictive tests of the entropic gradient field framework, providing computational support for the theoretical results presented in the article. Included notebooks cover:• planetary magnetic dipole moment scaling,• solar and stellar magnetic cycles,• planetary magnetism (including Venus and Uranus),• relativistic corrections and perihelion precession,• saturation-driven field regularisation. Each notebook corresponds to specific sections of the article and includes simulation code, validation frameworks, and predictive models. All results are obtained without empirical fine-tuning and rely exclusively on the entropic field formalism developed in the accompanying work.
