The modification of newton’s gravitational law and Its application in the study of dark matter and black hole

In this paper, Newton’s gravitational formula is modified by the principle
of spatial energy field superposition, and the problem of “missing mass “ of
galaxies is analyzed by this modified gravitational formula. It is concluded
that the velocity of stars in the galaxy is too fast because the energy field
intensity of the inner space of the galaxy or space-time curvature of the galaxy
is seriously underestimated, and there is no dark matter and supermassive
black hole in the galaxy.
