Scientists have built and tested a world-first nuclear clock prototype, which could potentially outperform atomic clocks. The new clock works by measuring the vibrations of an atom’s nucleus, rather than its entire structure. This allows for even more precise timekeeping, with the potential to speed up GPS and internet technologies.
Atomic clocks keep time by counting the vibrations of certain atoms, but nuclear clocks could be even more accurate. By focusing on the nucleus instead of the entire atom, nuclear clocks can achieve a much higher number of “ticks” per second. This increased precision also makes it more stable against disturbances like electromagnetism.
The prototype uses thorium-229 and an ultraviolet laser to excite the protons and neutrons in the nucleus. The team plans to continue developing the technology and expects to surpass atomic clocks in two to three years. If successful, nuclear clocks could revolutionize communications, internet, GPS, and other technologies.
