Physicists at NYU have discovered a new type of time crystal—an exotic state of matter whose particles rhythmically “tick” while levitating on sound waves.

A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

This puzzle is known as the problem of time, and it remains one of the most persistent obstacles to a unified theory of physics. Despite enormous progress in cosmology and particle physics, we still ...

In physics, the treatment of time is a central issue. In physics, the treatment of time is a central issue. It has been treated as a question of geometry. One can measure time and treat it as a ...

Time is not to be trusted. This should come as news to no one. Yet recent times have left people feeling betrayed that the reliable metronome laying down the beat of their lives has, in a word, gone ...

The flow of time isn’t as consistent as we might think – gravity slows it down, so clocks on the surface of Earth tick slower than those in space. Now researchers have measured time passing at ...

Time travel movies have different rules about what happens when you start messing around with the timeline. If you’ve ever wondered which ones make the most sense, we may now have an answer. According ...
