Newton's universal law of gravitation states that every body in the universe attracts each other, but he did not explain the reason for this attraction. The formula F = (Gm1m2)/r² calculates the gravitational force between two objects but does not clarify the underlying mechanism of attraction. Newton's law is a mathematical relationship based on empirical observations and leads to the derivation of Kepler's laws of planetary motion. His initial reluctance to publish results stemmed from inconsistencies in applying his theory to the moon's position, which he later addressed with the help of Halley. The discussion highlights the distinction between the law itself and the lack of explanation for the fundamental nature of gravity.
