A large-scale heuristic modification of Newtonian gravity as alternative approach to the dark energy and dark matter

TL;DR

This paper proposes a large-scale modification to Newtonian gravity by adding an inverse Yukawa-like field, aiming to address dark energy and dark matter issues within a unified framework consistent with observations.

Contribution

It introduces a novel inverse Yukawa-like gravitational field that modifies Newtonian gravity on large scales, providing an alternative explanation for dark energy and dark matter phenomena.

Findings

Removes incompatibility between universe flatness and matter density

Predicts a graviton mass of at least 10^-64 kg

Aligns with astronomical and laboratory observations

Abstract

The peculiarities of the inverse square law of Newtonian gravity in standard Big Bang Cosmology are discussed. It is shown that the incorporation of an additive term to Newtonian gravitation, as the inverse Yukawa-like field, allows remove the incompatibility between the flatness of the Universe and the density of matter in the Friedmann equation, provides a new approach for dark energy, and enable theoretical deduce the Hubble-Lemaitre's law. The source of this inverse Yukawa-like field is the ordinary baryonic matter and represents the large-scale contribution of gravity in accordance with the Mach's principle. It's heuristically build from a specular reflection of the Yukawa potential, in agreement with astronomical and laboratory observables, result null in the inner solar system, weakly attractive in ranges of interstellar distances, very attractive in distance ranges comparable to the clusters of galaxies and repulsive in cosmic scales. Its implications in the missing mass of Zwicky, Virial Theorem, Kepler's Third Law in Globular Clusters, rotations curves of galaxies, gravitational redshift and the Jean's mass are discussed. The inclusion of the inverse Yukawa-like field in Newtonian gravitation predicts a graviton mass of at least 10-64 kg and could be an alternative to the paradigm of non-baryonic dark matter concomitant with the observables of the Big Bang.
