The most precise clocks ever built are now testing Einstein, hunting dark matter, and reshaping how we define time itself. In ...
Doomsday Clock warns humans are trending closer to catastrophe at 85 seconds from midnight. Here's what to know.
A new software package detailed by Chinese scientists promises to tell what time it is on the moon, accounting for effects of relativity.
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 ...
China has quietly solved a problem that only becomes obvious once you try to live and work off-world: clocks on the moon do ...
JILA researchers measured time dilation, or how an atomic clock's ticking rate varied by elevation, within this tiny cloud of strontium atoms. Credit: Jacobson/NIST JILA researchers measured time ...
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 ...
