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 ...

It feels so obvious that time moves forward that questioning it can seem almost pointless.

Time is not to be trusted. This should come as news to no one. Yet recent times have left people feeling betrayed that the reliable metronome laying down the beat of their lives has, in a word, gone ...

“This retroactive idea. It has to be that,” says Nobel Prize-winning mathematical physicist Sir Roger Penrose, reflecting on a problem about the building blocks of reality that has dogged physics for ...

The original version of this story appeared in Quanta Magazine. To catch a glimpse of the subatomic world’s unimaginably fleet-footed particles, you need to produce unimaginably brief flashes of light ...

Arts and Science researchers developed particles that use sound waves to swing in the air without external forces to determine their rate of oscillation. The discovery could further research on other ...

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand 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 ...
