The universe and the solar system - Part 1

The video explains the evolution of the solar system based on Pierre Simon Laplace's nebular hypothesis. Laplace proposed that the solar system originated from a glowing gaseous sphere, or nebula, which contracted and increased its rotation speed over time. This led to the formation of a flat rotating disk, from which gaseous rings separated and eventually cooled to form the planets. The remaining central mass became the Sun.

What happens to the nebula as it loses heat over time?

Explain how the planets of the solar system were formed according to the nebular theory.
