Cosmic Events and Galaxy Formation

The video provides an overview of the universe, focusing on the Milky Way galaxy's structure and location. It explains the classification of galaxies, including elliptical, spiral, and irregular types. The video explores the scale of the universe, from the solar system to superclusters, and discusses the concept of redshift as evidence of the universe's expansion. Finally, it delves into the Big Bang Theory, detailing the universe's formation and evolution over billions of years.
