      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 removing the incompatibility between the flatness of the Universe and the densityof matter in the Friedmann equation, provides a new approach for dark energy, and enables theoretical deduction of the Hubble–Lemaitre 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 principle. It isheuristically built from a specular reflection of the Yukawa potential, in agreement with astronomical and laboratory observables, resulting 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 cosmicscales. Its implications in the missing mass of Zwicky, virial theorem, Kepler’s third law in globular clusters, rotation curves of galaxies, gravitational redshift, and 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.

    • Continuous Article Publication

      Posted on January 27, 2016

      Since January 2016, the Journal of Astrophysics and Astronomy has moved to Continuous Article Publishing (CAP) mode. This means that each accepted article is being published immediately online with DOI and article citation ID with starting page number 1. Articles are also visible in Web of Science immediately. All these have helped shorten the publication time and have improved the visibility of the articles.
