Berlin: German experts have measured the shortest period of time, which is only 247 zepto seconds. This time measurement is based on the observation that a photon travels from one end of a hydrogen atom to the other (53 pcm), the shortest measurement of time in human history to date.
Earlier, the record for the shortest measurement of time was also set by German scientists, which was 850 zepto seconds. The new record is even 3.4 times shorter.
Explain that a zeptosecond means “one thousandth of a billionth of a billionth of a second”.
This period of time is so short that if we imagine a zeppo second as a second, our current “one second” period would be equal to 31,700 billion years (thirty-one thousand seven hundred billion years); that is, the current age of our universe. 2,365 times more than (13 billion 800 million years)!
The shortest measurement of time was made by scientists at the Goethe University Frankfurt, Deutsche Electron Synchrotron Accelerator (DESY) Hamburg and the Fritz Heber Institute Berlin.
Although the experiment was essentially the same as the one performed in 2016, the previous measurements used helium atoms and ultraviolet rays, while the new experiment could measure even shorter amounts of time by scattering X-rays on hydrogen atoms. Made.
Details of the study are published online in the latest issue of the research journal Science.
It should be noted that most important and fundamental phenomena of nature occur in a very short time. That is why measuring the shortest periods of time is important to us.
In 1999, the Nobel Prize in Chemistry was awarded to Dr. Ahmed Zweil, an Egyptian professor, for his key role in “femto-chemistry”, making it possible for the first time to observe any chemical process at tens of thousands of seconds per second. One trillionths as small as possible.
