What does the nebular hypothesis suggest?

The nebular hypothesis suggests that the solar system formed from a rotating cloud of gas and dust, known as a solar nebula. As this nebula collapsed under its own gravity, it spun faster and flattened into a disk, causing material to clump together and form the Sun at its center, while planets, moons, and other celestial bodies formed from the remaining material. This theory explains the observed patterns of motion and composition in the solar system.
