Cosmic Background Radiation Concepts

The video explores the cosmic microwave background radiation (CMB), the oldest light in the universe, originating from the Big Bang. It explains how the universe transitioned from a dense, hot state to a transparent one, allowing light to travel freely. The CMB provides insights into the universe's temperature and structure, revealing quantum fluctuations that led to the formation of galaxies and other cosmic structures. An interactive map offers a visual exploration of the CMB, likening it to a fantasy world map.
