Considering our recently proposed light speed expanding and rotating primordial black hole universe and by following Modified Newtonian Dynamics (MOND), an attempt is made to estimate the galactic dark mass and galactic flat rotation curves. Basic idea is that, galactic dark mass is a representation of weakly interacting massive foam and its magnitude is proportional to . Considering current cosmic maximum angular acceleration, MOND’s approach implicitly seems to support the cosmological estimation of 95% invisible matter and 5% visible matter. With reference to Metric Skew Tensor Gravity (MSTG) and MOND approaches, in fitting the galactic flat rotation curves, for 101 galaxies, average error is -2.1% and 6.8% respectively. Estimated total mass of Milky Way is 2.28 Trillion solar masses and is matching with the upper mass limit of most recent studies.
