Is the universe itself the ultimate editor of history, quietly erasing any contradictions before they can even take root? That’s the provocative implication of new research from Lorenzo Gavassino, a ...

Scientists built a tiny clock from single-electron jumps to probe the true energy cost of quantum timekeeping. They discovered that reading the clock’s output requires vastly more energy than the ...

Quantum timekeeping is supposed to be the ultimate in efficiency, with tiny devices that tick using the rules of quantum mechanics instead of swinging pendulums or vibrating quartz. Yet new work on a ...

Physicists are rethinking time itself. Long treated as a basic part of the universe, time may instead be an illusion—a side effect of quantum entanglement. A new study challenges the traditional idea ...

The dream of time travel has fueled stories, films, and scientific debates for generations. The idea that you could step into a machine and reappear in another era has captivated people for as long as ...
