Ekkehard Peik, one of the field’s pioneers, says such a clock could be a factor of 1,000 times better than today’s standard atomic clocks.

Nuclear clocks would keep time using a variety of the element thorium, called thorium-229. Most atomic nuclei make energy leaps that are too large to be triggered by a tabletop laser.

The National Institute of Standards and Technology's new cesium fountain clock is one of the most precise atomic clocks ever created.

Atomic clocks have served as the world’s most precise means of measuring time for over 70 years, but their reign may be finally coming to an end.
