In this paper, it will be explained pedagogically about the necessity of the emergence of the hypothesis of dark matter in an effort to maintain the existing theory of gravity. Astronomical observations of the rotation of stars in the center of galaxies show very large deviations from the predictions of existing gravitational theories. To maintain the theory of gravity, a new hypothesis is needed, i.e . by emerging the concept of dark matter. Dark matter is thought to play a major role in its interaction with gravity throughout the universe and is responsible for the regularity of the rotation speed that is (almost) constant from all galaxies in the universe.
