Zeptosecond is the smallest measurement of time ever recorded
The shortest amount of time ever recorded has been discovered by scientists. The unit is called zeptosecond and represents one trillionth of a billionth of a second. Using the measurement, physicists from Goethe University Frankfurt recorded the time taken by a photon to cross a hydrogen molecule. The time came was 247 zeptoseconds. A hydrogen molecule was irradiated using X-rays from a Petra III laser for the calculation.
