The first ticking ‘nuclear clocks’ are here — what can they do?

AI Insight

Two independent research teams have successfully developed the first functioning nuclear clocks, a new type of atomic timekeeper that uses energy transitions in atomic nuclei rather than electron transitions. These clocks represent a significant advancement in precision timekeeping technology that scientists have been working toward for years. Nuclear clocks operate by measuring transitions in thorium-229 nuclei, which occur at much higher frequencies than traditional atomic clocks.

Why it matters

Nuclear clocks could potentially be even more precise than current atomic clocks, which already form the basis for GPS systems, internet synchronization, and fundamental physics experiments. The enhanced precision could enable more sensitive tests of fundamental physics theories, improve navigation systems, and detect subtle phenomena like gravitational waves or variations in fundamental constants.
