There’s an adage coined by [Ian Betteridge] that any headline ending in a question mark can be answered by the word “No”.

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 ...

General Relativity, Einstein’s seminal theory of gravitation, remains a pillar of modern physics by describing gravity as the curvature of spacetime. Nonetheless, persistent questions—ranging from the ...

The question “What time is it on Mars?” is far more complicated than you might expect. That’s because the passing of time is affected by the strength of gravity, according to Einstein’s theory of ...

For over a century, physicists have grappled with one of the most profound questions in science: How do the rules of quantum ...

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 ...
