Everyone knows that time flows in one direction, with events occurring in a sequence. Time’s unidirectionality is linked to entropy, the unstoppable urge of any system to become increasingly ...

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 ...

Quantum systems may defy classical time irreversibility, revealing bidirectional entropy flow and prompting a reevaluation of ...
