The most precise clocks ever built can now detect gravity’s warping of time across a distance shorter than a pencil tip. That ...

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

If an atomic physicist like Nathan Lundblad could slip the surly bonds of Earth’s gravitational pull, what kind of experiment would he dream up? About a decade ago, that very question was posed to ...

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 ...

The results are an important stress test for theories and future experiments in atomic physics. 1.97007 femtometre (quadrillionths of a metre): That’s how unimaginably tiny the radius of the atomic ...

In March 2018, researchers launched what looks like a white, cooler-sized fridge to the International Space Station. That heavy box houses a $100 million facility known as the Cold Atom Laboratory, ...

Cold atom experiments trap atoms to probe quantum effects, enabling ultra-precise sensing, timekeeping, and monitoring of Earth and space phenomena. (Nanowerk News) Cold atom experiments are among the ...
