According to a statement published on Wednesday in the journal Nature, scientists at the University of Wisconsin–Madison have developed one of the highest-performing atomic clocks ever. The device is believed to be so precise that it loses only one second per 300 billion years, enabling more accurate measurements of gravitational waves, dark matter, and other physical phenomena. Atomic clocks operate by monitoring electrons' energy levels.
