The scientists at the National Institute of Standards and Measurement have one big job: to measure things as accurately as possible. To do that, they build a lot of big and complicated machines, ...

A newly-designed atomic clock uses entangled atoms to keep time even more precisely than its state-of-the-art counterparts. The design could help scientists detect dark matter and study gravity's ...

Scientists have now constructed atomic clocks so precise and sensitive that they can measure the gravitational distortion of spacetime and may even help solve the mystery of dark matter. The latest ...

PLEASANTON, Calif.--(BUSINESS WIRE)--Vector Atomic is developing atomic inertial sensors for GPS-free navigation and geophysical exploration. On March 29, Vector Atomic will present results from a 20 ...

Next-generation atomic timekeeping techniques could push new frontiers in quantum physics, according to a new study. Atomic clocks are essential elements in GPS and other navigation systems — and a ...

The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It’s a ...

Time might feel like something we've got a pretty good handle on, but scientists are trying to find new ways to measure it ever more accurately. In recent tests run by the National Institute of ...

Two atomic clocks have been connected using quantum entanglement – a property that intrinsically links them so that changes in one instantaneously affect the other. The connection makes it easier to ...

Atomic clocks. They almost sound like something out of science fiction, or an experiment confined to some elite physics lab, but in reality, they’ve been around since the 1950s in one form or another.
