Understanding What role does gravity play in cosmic structure?
Gravity causes gas clouds to collapse into stars, keeps planets in orbit, and holds galaxies together.
A deeper explanation
According to Einstein's theory of general relativity, gravity is not simply a force but a result of matter and energy bending the fabric of spacetime. On cosmic scales, gravity determines how the universe evolves and how structures form.
