What is gravity responsible for in space?

Gravity is responsible for the formation and stability of celestial bodies, such as stars, planets, and galaxies, by pulling matter together to create mass. It governs the orbits of planets around stars and moons around planets, maintaining the structure of solar systems. Additionally, gravity influences the movement of galaxies and the dynamics of large-scale structures in the universe. Ultimately, it plays a crucial role in the evolution and behavior of the cosmos.
