Nebular Hypothesis

The Nebular Hypothesis is a scientific idea explaining how our solar system formed. It suggests that about 4.6 billion years ago, a giant cloud of gas and dust in space, called a nebula, started to collapse under gravity. As it collapsed, it spun faster and flattened into a rotating disk. Most material gathered in the center to form the Sun, while particles in the outer regions clumped together to create planets, moons, asteroids, and other objects. This process explains the solar system's structure and the reasons planets orbit the Sun in a relatively flat, organized manner.
