Gravitational interactions are fundamental forces that govern the attraction between objects with mass. This force is responsible for keeping planets in orbit around stars, moons around planets, and even galaxies bound together. The strength of this interaction depends on the masses of the objects involved and the distance between them, as described by Isaac Newton's law of universal gravitation. In the realm of Einstein's general relativity, gravitational interactions are viewed as the curvature of spacetime caused by mass. This revolutionary perspective helps explain phenomena such as the bending of light around massive objects and the behavior of objects in strong gravitational fields, deepening our understanding of the universe's structure and dynamics.
