Exactly 200 years ago, a French engineer introduced an idea that would quantify the universe’s inexorable slide into decay. But entropy, as it’s currently understood, is less a fact about the world ...

Everyone knows that time flows in one direction, with events occurring in a sequence. Time’s unidirectionality is linked to ...

Time has an arrow: It only ever seems to move in one direction. The future is always unknown to us, while the past forever remains locked and inaccessible. And yet, the vast majority of the laws of ...

Time’s passage is non-negotiable. Its flow marks the progress of our lives, moving clearly in one direction. It is, by nature, asymmetrical. In this way, we perceive it to move like an arrow, ...

Scientists have shown, through probabilistic calculations, that there is indeed, as had been hypothesized, a rule of 'entropy' for the phenomenon of quantum entanglement. This finding could help drive ...

Where does time really come from? I am often asked this question after acquaintances or friends of friends learn that I am a physics reporter. There is not a set answer – but to better understand it, ...

Researchers in China have proposed a theory explaining why time moves only forward. Scientists from Hainan University in southern China proposed a new theoretical framework that sheds light on this ...
