Methuselah's Star and the Age of the Universe

The video explores the age of the universe, estimated at 13.8 billion years, and the methods used to determine this, including the universe's expansion and redshift. It discusses assumptions about the universe's uniformity and the role of dark matter and dark energy. The Methuselah Star, potentially older than the universe, challenges current estimates. Future research with advanced telescopes may refine these figures.
