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 ...

A team of New York University researchers announced in early February 2026 that they had created “levitating” time crystals, tiny particles suspended by sound waves that appear to defy Newton’s third ...

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 ...

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 ...

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 ...
