The reconciliation of general relativity and quantum mechanics is one of the biggest challenges in science, one that continues to elude us. Now, a new study by Anjun Chu and colleagues has examined ...

Researchers have explored the interplay between gravitational effects and quantum interactions in optical atomic clocks, revealing more about quantum entanglement in precision timekeeping. For over a ...

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 ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that ...

Clocks on Mars tick faster by about 477 microseconds each Earth day, a new study suggests. This difference is significantly more than that for our moon, posing potential challenges for future crewed ...

Observing time distortions could show whether Einstein's theory of general relativity accounts for the mysteries of dark matter and dark energy. When you purchase through links on our site, we may ...

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 ...

On average, Martian time ticks roughly 477 millionths of a second faster than terrestrial clocks per Earth day. But the Red ...

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 ...

A recent study published in Nature details a significant advancement in the creation of practical nuclear clocks.
