One of the fundamental mysteries surrounding the concept of time is whether it's continuous and our chronological measurements are just a way of making the sense of the world, or if it actually breaks ...

Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule. That time, for the record, is 247 zeptoseconds. A zeptosecond is a trillionth ...

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 ...

The smallest conceivable length of time might be no larger than a millionth of a billionth of a billionth of a billionth of a second. That's according to a new theory describing the implications of ...
