Scientists have measured the world's smallest unit of time, and it's called the zeptosecond. It was recorded by a group of scientists at Goethe University, in Germany and published in the Science ...

Scientists successfully measured an event using zeptoseconds, which is an incredibly brief fraction of a second. The time it took for a photo to pass through a hydrogen molecule was measured at 247 ...

A team of physicists have recorded the shortest possible measurement of time: the zeptosecond. A zeptosecond is a trillionth of a billionth of a second. Or, to give it its numerical value: ...
