Once considered an oddity of quantum physics, time crystals could be a good building block for accurate clocks and sensors, ...

Keeping perfect time is far trickier than it sounds. The world’s best clocks that ...

Time travel has shifted from pure fantasy to a serious, if highly constrained, topic in modern physics. The equations that describe gravity, quantum fields and the structure of spacetime now allow ...

Some quantum systems may have two arrows of time, one running forwards as usual and another moving backwards. This means that, at some extremely small scales, time may have the option of moving in ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

A team at New York University has discovered a new form of time crystal that hovers using sound waves. Unlike ordinary matter, these crystals seem to behave in ways that don’t align with Newton’s ...

It could be a good time event. The Sands of Time: The Physics of Time, 7 p.m., Tuesday at Marie Drake Planetarium, 1415 Glacier Ave., will cover how the concept of time is impacted by physics. The ...

Time feels like the most basic feature of reality. Seconds tick, days pass and everything from planetary motion to human memory seems to unfold along a single, irreversible direction. We are born and ...
