JILA physicists have measured Albert Einstein’s theory of general relativity, or more specifically, the effect called time dilation, at the smallest scale ever, showing that two tiny atomic clocks, ...

Cool research story with connections to atomic clocks, Einstein and quantum mechanics. The research shows the 'spooky' interference that can impact even the most sophisticated clocks. A phenomenon of ...

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 ...

Physicists have long treated space and time as the stage on which quantum particles perform, not as actors in the drama ...

Earth’s gravity distorts spacetime. As far as we know, every point on Earth experiences time and space differently by a minuscule — but measurable — amount. Atomic clocks are one of the ways to detect ...

In another verification of the validity of Einstein's theory of general relativity scientists have used two finely tuned optical lattice clocks to make new ultra-precise measurements of the time ...

PHYSICS HAS A problem. In general relativity, time is entwined with space. It is relative, depending on speed or gravity. In quantum mechanics, however, time is an absolute. It is a smooth background ...

Adam Deller receives funding from the Australian Research Council. Richard Manchester has received funding from the Australian Research Council. CSIRO provides funding as a founding partner of The ...

In the gloomy days of January, time seems to drag. According to the Einstein theory of relativity, it actually does—in a minute amount that means little to anyone except a scientist. During its annual ...

Clocks on the Red Planet run almost 500 microseconds faster per Earth day than they do here at home. This also has consequences for settlement plans. On average, clocks on Mars run 477 microseconds ...

HANOVER, N.H. - October 23, 2020 - A phenomenon of quantum mechanics known as superposition can impact timekeeping in high-precision clocks, according to a theoretical study from Dartmouth College, ...
