Breakthrough ion clock experiments reveal that time can go quantum

Time already behaves strangely in modern physics. It can stretch, slow, and split depending on speed and gravity.

New nuclear clock precision could help redefine the second, researchers say

A string of experiments using thorium-229 nuclei has brought the long-theorized nuclear clock closer to reality, producing frequency measurements stable enough to challenge the atomic clocks that ...

Bringing quantum time into the lab—a single clock can run young and old at once

Few concepts in physics are as familiar, yet as enigmatic, as time. In Einstein's theory of relativity, time is not absolute: its passage depends on motion and gravity. But when combined with quantum ...
