The Nebular Hypothesis

The Nebular Hypothesis is a scientific theory that explains how stars and planets form. It suggests that our solar system began as a large cloud of gas and dust in space, known as a nebula. Over time, gravity pulled this material together, causing it to spin and flatten into a disk. In the center, the Sun formed, while the remaining material clumped together to create planets, moons, and other celestial bodies. This process occurred about 4.6 billion years ago and helps us understand the origins and structure of our solar system.
