In this paper, we will demonstrate, based on reasoning as well as mathematical evidence and experimental observations, why Newtonian gravity moves at the speed of light and is not, as previously thought, instantaneous. The misunderstanding that Newtonian gravity is instantaneous has constrained our progress in understanding gravity to its full extent. We will show that all of Newton's gravitational phenomena contain the Planck length and the speed of gravity; this speed of gravity is identical to the speed of light. A series of gravitational phenomena that are considered to be non-Newtonian and most often explained by the theory of general relativity actually contain no information about the speed of gravity. However, all observable gravitational phenomena which we will look at here can be predicted from the Planck length and the speed of gravity alone, and we can easily extract both of them from gravitational phenomena with no knowledge of any physics constants. In addition, we can also measure the speed of light from electromagnetic phenomena and then extract the Planck length from any of Newton's gravitational phenomena with no knowledge of G or h.
