Universal Law of Gravitation

Isaac Newton revolutionized our understanding of forces by proposing that the same laws of physics apply universally, not just on Earth. His Universal Law of Gravitation explains that all objects attract each other with a force proportional to their masses and inversely proportional to the square of the distance between them. Earth's gravity is stronger than other celestial bodies due to its mass and proximity. Even in space, gravity is never zero; it just diminishes with distance. Newton's insights laid the foundation for modern physics.
