An optical lattice clock embedded in the curved spacetime formed by the earth’s gravity. Dynamical interplay between photon-mediated interactions and gravitational redshift can lead to entanglement ...

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 ...

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 moves faster on Mars than on Earth. Physicists have confirmed this effect, crucial for future space missions. Even tiny ...

Can Mars let humans age faster? It sounds more poetic than reality, but it may be true technically. Two identical clocks: One on Earth other on Mars, .

Thanks to Albert Einstein, the US Government wants to establish an official time zone for the Moon. It has less to do with jet lag and more to do with how gravity affects time and can throw a lot of ...

When you buy through links on our articles, Future and its syndication partners may earn a commission. A lunar eclipse seen near a golden clock tower in Thailand. Time on the moon ticks slightly ...

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 ...
