Quantum batteries could charge by breaking our understanding of time

Causality is key to our experience of reality: dropping a glass, for example, causes it to smash, so it can’t smash before it’s dropped. But scientists have now demonstrated how that understanding of time can be violated to charge a quantum battery.
