Where Did the Big Bang Happen?

The video explores the universe's nature, starting with the Big Bang theory, which describes the universe's rapid expansion from a hot, dense state. It explains how galaxies appear differently based on their distance and the time it takes for their light to reach us. The universe's structure, influenced by gravity, forms filaments and voids. The Hubble constant measures the universe's expansion rate, defining the observable universe's limits. The cosmic microwave background provides a glimpse into the universe's early state, offering insights into its history and structure.

Explain why there is no center of the universe.
