SUMMARY
Scientists utilize cosmic background radiation to map the universe's size, shape, and age through techniques such as redshift measurements. By analyzing radiation wavelengths emitted by celestial bodies, they can determine distances and ages, with quasars serving as key indicators due to their immense distances, such as 15 billion light years. This method allows researchers to look back in time, providing insights into the universe's evolution. For further reading, refer to the article available at NASA's Goddard Space Flight Center.
