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 ...

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

A strange form of matter called a time crystal has fascinated physicists for about a decade. These systems move in repeating ...

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 ...

Time may not be a fundamental element of our physical reality. New calculations add credence to the idea that it emerges from quantum entanglement, in which two objects are so inextricably linked that ...

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 ...
