The first ticking ‘nuclear clocks’ are here
Scientists have developed the first "nuclear clocks" that measure time using atomic nuclei, not electrons. These devices could offer even more precise timekeeping than current atomic clocks. The breakthrough could improve technologies that rely on ultra-accurate timing, like GPS and scientific research.
These radical new devices keep time using fluctuations in the energy states of an atom’s nucleus, rather than those of its electrons, which atomic clocks currently use to define the length of a second
