La teoría del Big Bang

The video explains the Big Bang theory, describing the universe's origin from a small, dense point that expanded rapidly. It covers the formation of matter, hydrogen, and helium atoms, and the development of nebulae, stars, and galaxies, including the Milky Way. The solar system formed 9 billion years after the Big Bang, and the universe continues to expand indefinitely.

How did nebulae contribute to the formation of galaxies?
