Is gravity just dark matter and dark energy?

COULD #DARK_MATTER AND #DARK_ENERGY JUST BE EXPRESSIONS OF #GRAVITY? #The_large_scale_structure_of_the_universe can be likened to soapsuds. A single bubble is mostly empty space with a thin shell. Astronomically, the bubble is a large-scale space-time void and the shell is a grouping of #galaxies (#galactic_superclusters). The void is expanding according to the #Hubble_Law. When bubbles of various sizes are themselves grouped together the result is the observed #accelerated_expanding_universe. Most of the expansion is in the voids. When two such expanding bubbles are tangent, an #attractive_gravity could be apparent (dark matter below the supercluster scale?). Across a single large-scale void accelerated expansion is a logical (if not observable) element of accelerated universal expansion (dark energy?). In that acceleration and gravitation are commonly equivalent, they may very well be identical, where the repulsive (primary) effect is #repulsive_gravity. Whether the effect is dark matter or dark energy would depend only on scale or viewpoint. #astrophysics #astronomy #cosmological_constant
