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 ...

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

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Time feels steady and familiar in daily life, but at the quantum level it becomes slippery. That puzzle now has a fresh twist ...

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 ...

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 ...

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 ...

Over the short span of just 300 years, since the invention of modern physics, we have gained a deeper understanding of how our universe works on both small and large scales. Yet, physics is still very ...

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 ...

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 ...
