In other words, whether time travel is possible or not is a quandary beyond the remit of classical physics. And since quantum gravity remains an elusive thing, the jury’s out on time travel.

While time travel is fundamental to Doctor Who ... or even worse. Getty Images In quantum physics, an effect that occurs in one place can alter the state of something in another – it's pretty ...

Our universe plays by certain rules, which originate from different branches of physics. But sometimes the rules seem inconsistent with each other or don’t quite line up. And in other cases the rules ...

In the new work, Arvidsson-Shukur, McConnell and Yunger Halpern do just that by investigating what advantages simulations of backward time travel can have for quantum metrology – a field of physics ...

"A negative time delay may seem paradoxical, but what it means is that if you built a 'quantum' clock to measure ... can get ...
