Laser-Tuned Nuclear Clock Would Be Accurate for Billions of Years

By  |

Researchers have proposed building a nuclear clock that would lose only one-tenth of a second over 14 billion years, the current age of the universe.

The design would be 100 times more accurate than current atomic clocks and might be used in applications such as higher-precision GPS satellites and experiments that probe fundamental physics.

Atomic clocks measure time using the oscillations of a single atom and are accurate to 17 decimal places. They are in widespread use for GPS measurements and synchronization in particle accelerator experiments, and you can even set your laptop to one.
