A new theory called, the Dark Matter Flow Theory based on fluid mechanics concepts, has been given for the first time to derive the density of the dark matter and its distribution inside galaxies and beyond. Although the results are chocking, however they exhibit a high congruence with the measured observations of the velocity rotation curves of galaxies. Also, the paper proposes a more general density profile with cosmic parameters that covers most types of galaxies. A comparison with the rotation disc velocities of the spiral galaxies NGC 4841, NGC 3198 and our Milky Way Galaxy has been given. The high congruence between the theory and the measured observations confirms the correctness of the theory proposed. The paper studies the variation of the cosmic parameters of the predicted disc velocities to show the wide range of galaxy's velocity curves covered by this theory. A comparison with NFW and Einasto profiles has been given, after adapting their equations with the derived results of this paper, to show the high accuracy of our given profile. An estimation of the mass of the dark matter particle has been given, which shows that it is within the range of CERN's reactivation in late 2014, which could be detected by CERN. The paper is considered a bold step in understanding the nature of dark matter and shows our inability to fully understand the physical world so far.
