Gravity Theory

Gravity Theory explains how objects attract one another due to their mass. In celestial mechanics, this means that planets, stars, and moons influence each other's motion through gravitational forces. The more massive an object, the stronger its gravitational pull. This interaction dictates orbits, causing planets to revolve around stars and moons around planets. Isaac Newton initially formulated this idea, describing gravity as a force, while Albert Einstein later refined it, presenting gravity as the curvature of space-time caused by mass. Essentially, gravity keeps celestial bodies in their paths and shapes the structure of the universe.
