Universal Gravitation
Universal Gravitation, formulated by Sir Isaac Newton, is the principle that every mass attracts every other mass in the universe. The strength of this attraction depends on two factors: the masses of the objects and the distance between them. The larger the masses, the stronger the gravitational pull; the farther apart they are, the weaker the pull. This concept explains why planets orbit the Sun, why we stay grounded on Earth, and governs the motions of celestial bodies throughout the cosmos. Essentially, it's the force that keeps everything anchored in the vastness of space.
