Gauss's law for gravity

Gauss's law for gravity states that the gravitational attraction around an object can be understood by examining a closed surface surrounding it. The total gravitational force experienced by that surface is proportional to the mass inside it. Essentially, if you imagine a balloon around a planet, the strength of gravity pulling on the balloon depends only on the planet's mass, regardless of its size or shape. This principle helps in calculating gravitational effects in various scenarios, simplifying complex gravitational fields into manageable parts based on mass distribution.
