Scientists have measured the shortest unit of time ever: the time it takes a light particle to cross a hydrogen molecule.
- According to a team of scientists from Germany, that time, for the record, is 247 zeptoseconds.
- A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1.
- The findings are the culmination of global efforts to measure shorter and shorter time spans in physics, and they offer scientists a way to precisely measure atomic changes through what’s known as the photoelectric effect.
