For decades, atomic clocks have provided the most stable means of timekeeping. They measure time by oscillating in step with ...

(TNS) — In 2003, engineers from Germany and Switzerland began building a bridge across the Rhine River simultaneously from both sides. Months into construction, they found that the two sides did not ...

Clocks on Earth are ticking a bit more regularly thanks to NIST-F4, a new atomic clock at the National Institute of Standards and Technology (NIST) campus in Boulder, Colorado. NIST-F4 measures an ...

The European Space Agency (ESA) has launched one of its most precise science experiments to date — the Atomic Clock Ensemble in Space (ACES)—to the International Space Station (ISS). This is no ...

Tracking time is one of those things that seems easy, until you really start to get into the details of what time actually is. We define a second as 9,192,631,770 oscillations of a cesium atom.

Time is relative. The ticking of the clock, even of the most precise clocks we can make, does not exist in an absolute. It depends on the gravity you are experiencing and on your speed. Being on the ...

The National Institute of Standards and Technology recently warned that an atomic clock device installed at its Boulder campus had failed due to a prolonged power ...

The Earth’s gravity, manifested as curvature in space and time, is expected to alter the rules of standard quantum theory. An experiment consisting of three quantum computers at different elevations ...
