Why Is The Universe So Empty? (ft. PHD Comics!)

The video explores the vast structures of the universe, from galaxies to superclusters, and questions why the universe has any structure at all. It explains that early quantum fluctuations, amplified by cosmic inflation, led to the formation of these structures. The cosmic microwave background provides evidence of these early fluctuations. The video also discusses the ongoing battle between dark energy and gravity, which shapes the universe's future. Depending on the balance of these forces, the universe could either form superduper clusters or be torn apart.
