How stuff works atomic clock
Nettet2. jun. 2024 · JILA scientists built a new atomic clock to measure time dilation across the smallest distance yet. A key feature is that its time-keeping atoms are stacked vertically above and below a one-millimeter gap, as illustrated in this video. A grandfather clock is a helpful way to picture how all these parts work together, Aeppli says.
