How to build a clock that detects gravity In Tokyo, researcher Katori Hidetoshi uses atomic clocks to see how gravity warps time ...

Scientists have used a portable “atomic clock” to measure gravity for the first time. The device makes use of small changes in the flow of time at different altitudes to measure the Earth’s ...

Quick, what time is it? At the Museum of Discovery and Science in Fort Lauderdale, telling time takes a little longer to figure out. Visitors who use the Great Gravity Clock have to study the place… ...

Our New Atomic Clock Is So Precise That We Need a Better Understanding of Gravity To Use It Our measurements of gravity are not good enough for NIST's new atomic clock.

The new clock takes a fundamentally quantum system — an atomic clock — and intertwines it with gravity’s pull. In the experiment, Ye’s team used an optical lattice clock, a cloud of 100,000 strontium ...
