How is this for a new measurement? (both)
There’s a new record for the shortest time measurement: how long it takes light to cross a hydrogen molecule.
To measure small differences in time, you need a really tiny clock, and researchers in Germany have discovered the smallest known clock: a single hydrogen molecule.
Using the travel of light across the length of that molecule, those scientists have measured the smallest interval of time ever: 247 zeptoseconds.
One zeptosecond is a trillionth of a billionth of a second, by the way.
