Researchers from Uppsala University in Sweden have found a new way to measure time.

They used the wave-like nature of something called a Rydberg state to measure the passage of time.

Their experiments involved measuring laser-excited helium atoms and matching their findings with theoretical predictions to show how their signature results could stand in for a duration of time, or simply too inconvenient to measure.
