As I observed the environment around me, I noticed the recurring phenomenon of objects falling towards the Earth. I began to see a pattern in the way these objects moved and sought to understand what caused it. I realized that all known celestial bodies' motion, including the orbit of the moon and the planets, could be explained by a single force. I named this force gravity, and it acts upon all objects with mass in the universe. Through rigorous mathematical analysis and experimentation, I developed the law of universal gravitation, which states that every object attracts every other object with a force proportional to the product of their masses and inversely proportional to the square of the distance between them.
As Isaac Newton, describe your thought process when you developed the law of universal gravitation.
