The laws of physics imply that the passage of time is an illusion. To avoid this conclusion, we might have to rethink the reality of infinitely precise numbers. Strangely, although we feel as if we ...

“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 ...

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 ...

Physicists have recently uncovered a groundbreaking material known as “time crystals,” which challenges our conventional understanding of time and space. This discovery, rooted in quantum physics, ...

“What is time? If no one asks me, I know what it is. If I wish to explain it… I do not know”, famously quipped Saint Augustine. Our modern understanding of time is more scientific than ever, and many ...

He was a gentleman who helped create the world’s most deadly weapon; a humble man who collected as many honors as almost any man of his time. Before he died of a heart attack last week at 77, Danish ...

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 ...

Time travel has long been dismissed as impossible due in part to the infamous "grandfather paradox." This conundrum asks what ...
