Meet the shortest time unit ever measured, zeptoseconds

Scientists have measured the shortest time unit ever: the time it takes for light particles to cross hydrogen molecule.

That time is 247 zeptoseconds for recording. Zeptoseconds are one billionth of a second, or decimal points followed by 21 zeros and ones. Previously, researchers were immersed in the area of ​​Zeptoseconds. In 2016, researchers will report in the journal Nature Physics A laser was used to measure the time in increments up to 850 zeptoseconds. This precision is a huge leap from the 1999 Nobel Prize-winning work. First we measured the time in femtoseconds. This is a millionth of a second.
