We experience the flow of time because it’s a natural outcome of the basic laws of physics. But we may need to build a whole ...

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 ...

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 ...

“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 ...
