Universe Expansion and Dark Matter

The video explores the universe's properties, focusing on whether it spins, is warped, or is flat. It discusses the concept of dark matter and dark energy, and how scientists have used telescopes like COBE, WMAP, and Planck to study cosmic background radiation. The findings suggest the universe is isotropic and non-rotating. Anomalies in the data, such as differing expansion rates, are also discussed.
