All the celestial bodies that make up the system are in free fall (acceleration) toward the center of the system. Gravity is the action that tries to maintain a defined acceleration towards the gravity source according to the distance from the gravity source. Therefore, if the gravity source accelerates, the gravitational action should be considered different from when the gravity source is stationary. Sciama named this action "inertial induction" and proposed it. All the stars that make up the galaxy are in free fall (acceleration) toward the center of the galaxy. Current calculation methods do not take this fact into account at all. There is no way that the observation can be explained by a calculation method that ignores the facts. I have written a paper* on how the inertial induction of stars works in galaxies. *N. Namba, "Stellar movement in the galaxy explained by inertial induction", Phys. Essays 15, 156(2002) In addition, I mentioned the essence of gravity and inertia in a 2014 paper, showing that the existing theory of gravity is incomplete.
