Abstract

Modified gravitation known as Scalar-Tensor- Vector-Gravity (STVG) and MOG and its consequences for dark matter and dark energy in astrophysics and cosmology and black holes is reviewed. A variable speed of light (VSL) cosmology is compared to inflation. MOG predictions for gravitational waves are compared to the LIGO/Virgo collaboration data. MOG – black hole predictions for the sizes of the Sagittarius A* shadow are compared to the sizes predicted by the Schwarzschild and Kerr solutions. A possible void cosmology is compared to the standard cosmology based on dark energy and the cosmological constant.
