It is the shortest time span that has been successfully measured to date. A zeptosecond is a trillionth of a billionth of a second.
In order to measure this event, scientists irradiated a hydrogen molecule using X-rays from the PETRA III laser, the most powerful light source of its kind.
According to Nbc news, 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.
