Scientists record the shortest period of time – New world measurement record



Scientists in Germany have measured the shortest length of time ever measured, setting a new world record for measuring short intervals. This is the time it takes for a particle of light (photon) to cross a hydrogen molecule and is equal to about 247 zeptoseconds. This is the shortest time ever measured on Earth. A zeptosecond is one trillionth of a billionth of a second or 10 ^ -21 seconds or the number 0 followed by a decimal point of 20 zeros and one. In 2016, scientists entered the infinitesimal domain of zeptoseconds, and a few years ago, in 1999, they were awarded the Nobel Prize for measuring intervals in the order of femtoseconds, that is, millionths of a billionth of a second ) with the help of short laser pulses. To create and break the chemical bonds between atoms, some femtoseconds are needed, but for light to travel through a molecule of hydrogen, the time is much shorter, only a few zeptoseconds.Now, for the first time scientists at the Goethe University in Frankfurt and the DESY particle accelerator in Hamburg, led by physics professor Reinhard Derner, who published in the journal Science, measured – with the help of X-rays and the high-precision COLTRIMS microscope – a process that is several orders of magnitude shorter than the femtoseconds.Source: ΑΠΕ-ΜΠΕ
