Not all atomic clocks can be used anywhere in the world as some only have compatibility with certain time zones. Using one of these outside a supported time zone could mean an inaccurate time ...

One of the biggest challenges in modern physics is uniting quantum mechanics and general relativity. A new experiment may ...

Possibly originating with the English poet Geoffrey Chaucer's "time and tide wait for no man," the idea that time waits for no man has been around for a long time. But time, or at least the latest ...

Atomic clocks work by using a laser to bounce the electrons in an atom at a given frequency, while nuclear clocks would theoretically do the same for atomic nuclei, and we are a step closer to ...

Last month, a consortium of 69 scientists from across Europe and Japan completed the largest and most coordinated comparison of optical clocks ever undertaken, bringing the world ...

Currently, the best atomic clock is so precise, it will essentially lose just one second every 300 billion years. Atomic clocks are sent into space regularly.

As the precision and portability of atomic clocks continue to improve, University of Delaware physicist Marianna Safronova and collaborators Yu-Dai Tsai of the University of California, Irvine, and ...
