The world’s best clocks may be sensitive to an odd mix of quantum and relativistic effects that would stretch time and test ...

Researchers find that a photon can spend a negative amount of time in an excited atomic state while passing through a cloud ...

Time-varying systems, materials with properties that change over time, have opened new possibilities for the experimental ...

“What is time? If no one asks me, I know what it is. If I wish to explain it… I do not know”, famously quipped Saint Augustine. Our modern understanding of time is more scientific than ever, and many ...

Physicists have unveiled a new type of time crystal that is governed by quantum behavior that conflicts with classical models ...

In an article published in Communications Physics, researchers from the Université libre de Bruxelles and the Institute for ...

The visible patterns produced by the time crystals could be used for data storage and anti-counterfeiting designs.

It bears repeating: the world is complicated. Oh, it looks simple enough: your coffee pours from pot to cup, round things roll but square things don’t, stuff that goes up will come back down (usually) ...

But what have been the most significant physics prizes of the 21st century? I’m including 2000 as part of this century (ignoring pedants who say it didn’t start till 1 January 2001 ). During that time ...
