Why does Newton’s law of universal gravitation apply to all objects in the universe?

Question

please answer

Answer 1

The theory is that everything is affected by gravity. The thing that differs is the mass of the object and its distance. So, when newton dropped the apple, it fell to the ground, but according to its mass and the distance from the ground. Essentially, everything in this universe attracts gravity, it only differs in the effect or observations based on the object, mass, and distance.
