Some events happen too fast to be captured in a photograph, no matter how quickly you hit the camera button. For example, certain quantum events are considered to be instantaneous, so they're hard to ...

For the first time, researchers have been able to measure the quantum state of electrons ejected from atoms that have absorbed high-energy light pulses. This is thanks to a new measurement technique ...

A millimeter might not seem like much. But even a distance that small can alter the flow of time. “This is fantastic,” says theoretical physicist Marianna Safronova of the University of Delaware in ...

What does the passage of time look like for a truly quantum object? The world’s best clocks may soon be able to answer this question, testing how time can stretch and shift in the quantum realm and ...

A CENTURY ago, two intellectual giants met to debate the nature of time. One was the French philosopher Henri Bergson, a superstar whose fans caused the first traffic jam on Broadway in New York as ...
