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 ...

Scientists have created a new kind of time crystal using sound waves to levitate tiny beads in mid-air. These particles ...

A growing body of theoretical and experimental work in physics is converging on a striking possibility: time, the dimension humans experience as a constant forward flow, may not be a fundamental ...

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 ...

An advanced laser technique has allowed researchers to observe, in real-time, the decomposition of a pollutant into atmospheric nitrous acid, which plays a key role in the formation of ozone and ...

After the passing of physicist Anthony Leggett, columnist Karmela Padavic-Callaghan remembers their personal connection with ...

It feels so obvious that time moves forward that questioning it can seem almost pointless. When you purchase through links on our site, we may earn an affiliate commission. Here’s how it works.

September 27, 2016 • It is plausible that in the ongoing expansion, the universe is creating not only new space but also new time — and each new moment is what we refer to as now, says guest blogger ...
