Hit the zeptosecond, the shortest unit of time ever recorded



Scientists have measured the shortest unit of time ever: the time it takes for a particle of light to traverse a hydrogen Molecule.

This time is 247 zeptoseconds. A zeptosecond is a trillionth of a billionth of a second, or a decimal point, followed by 21 zeros and a 1. Previously, researchers were immersed in the zeptosecond range. in 2016 researchers report in the journal Natural physics used lasers to measure time in steps of up to 850 zeptoseconds. This accuracy is a big leap from the 1999 Nobel Prize-winning work, which was the first to measure time in femtoseconds, which corresponds to millionths of a billionth of a second.
