What is the nebular hypothesis?

Question: Briefly describe the main idea and process of the nebular hypothesis in the formation of our solar system. Answer: The nebular hypothesis suggests that the solar system originated from a giant rotating cloud of gas and dust (solar nebula) that underwent gravitational collapse and subsequent condensation. In this process, the nebula transformed into a spinning disk, with its center forming the sun. Solid particles within the disk formed planetesimals that grew into protoplanets through collisions and gravitational pull. Some of these protoplanets became gas giants, while others became terrestrial planets. Finally, the remaining gas and dust were cleared through the solar wind, leaving the solar system we see today.
