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 ...

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 ...

Atomic clocks will only see a loss of 1 second in accuracy over a period of 10 million years. They are used in multiple ways, including the GPS in your car. Now researchers have found a way to bypass ...

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 ...

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 ...

A hundred years ago this week, at the height of the quantum revolution, Austrian physicist Erwin Schrödinger submitted a manuscript for publication. Its centerpiece was an innocuous-looking equation ...
