The Nuclear Clock: A Breakthrough in Measuring Fundamental Constants

This 20-minute video from Up and Atom explores a groundbreaking physics discovery that took 20 years to find - the nuclear clock. Learn about fundamental constants in physics and the revolutionary idea that these "constants" might actually change over time. Discover how atomic clocks work and why the newly developed nuclear clock represents a major scientific breakthrough that could test whether fundamental constants truly vary. The video features expert consultation from researchers at JILA/NIST/University of Colorado and UNSW's Department of Theoretical Physics, providing an accessible yet thorough explanation of this complex topic. Divided into sections covering the physics breakthrough, fundamental constants, their potential variability, atomic clock technology, and the revolutionary nuclear clock development.
