ABSTRACT: In a
recently published paper Metal-Like Gravity (MLG) and Its Cosmological Applications [1]
08D0C9EA79F9BACE118C8200AA004BA90B02000000080000000E0000005F005200650066003400310035003000360034003200330030000000
, it was determined that a new modification of Newtonian gravity could
explain many of the cosmological mysteries such as the nature of dark matter
and dark energy. The theory provided a gravitational physical system and
explained the flatness of the galactic rotational curves (RC). A RC fit that was
identical to MOND’s RC fit for spiral galaxies was generated with α as a fitting parameter determined as
equal to 1.345. In this paper I am elaborating more on the theory’s
cosmological extrapolation of MOND’s critical acceleration a0. This is done by further assessing the gravitational
interaction between the galactic baryonic mass and the halo-DM mass in the
star-galaxy overlapping volume estimated in MLG framework interpreting a0 as only a factor induced
from the reduction of the galactic luminous mass. It is asserted that MOND and
MLG dynamic equations are equivalent with MOND’s form, only expressing the
equation with an intermediate solution by equating the magnitudes of δ (a parameter that defines a scaled
surface galactic DM-density perpendicular to the galactic radial direction in
the galaxy-star halo overlapping volume) and G.
