Scientists search for shortest time scale: '247 Zaptoscands'

Scientists have discovered the smallest unit ever. They created by measuring how long it takes for a photon to pass through a proof of hydrogen.

It’s time 247 zaptosconds for the record. A zaptosecond is a billionth of a billionth of a second, followed by 20 zeros and 1 or a decimal point. This is equivalent to one femtosecond 0.0000000000000000001 seconds or 10-15 Seconds

Researchers had previously immersed themselves in the area of ​​Zaptoscand. In 2016, scientists published in the journal Nature physics Used lasers for a period of time up to 850 zaptosconds.

This is a big leap from the unit of measurement study that first measured time in femtoseconds, which is in the tens of millions of seconds, won the 1999 Nobel Prize.

Scientists have classified his discovery as the shortest time ever. This is approximately 247 zeptosconds (or 10)-21 Seconds, one trillion of a second).

Chemicals take femtoseconds to break bonds and form. On the other hand, a single molecule of hydrogen takes a zaptosecond to pass through light.

To measure this short journey, Reinhard Derner, a physicist at the University of Goethe in Germany, and his colleagues fired X-rays from Petra III at Hamburg’s Particle Accelerator, Dutsus Electron-Synchrotron (DESY).

The researchers determined the intensity of the X-rays so that both electrons were knocked out of the hydrogen molecule by a single photon or particle of light. One hydrogen atom has about two protons and two electrons.

The smallest size

One electron was bounced off the atom by a neutron, and the other, a little like a blanket tied to the surface of the ocean.

These interactions produced a wave pattern called an interference pattern, which could be calculated by Dorner and his associates with a device called a reaction microscope called cold target recall ion momentum spectroscopy. (COLTRIMS).

In short, this instrument is a highly sensitive particle detector that can incredibly speed up nuclear and molecular reactions.

“Because we know the local trend of Hydrogen molecule, We used to accurately calculate the interference of the waves of two electrons when the photon reached the first and when it reached the second hydrogen atom. Said in a statement.

Time? Two hundred and forty-seven zaptoskinds, with some wiggle space at the same time depending on the inner gap between the molecules of the hydrogen atom that the photon was poled. In short, the calculation captures the speed of light within the molecule.

“We noticed for the first time that electronic shells in a molecule do not react to light everywhere at the same time,” Darner said in a statement. “Time is delayed because the information inside the molecule only spreads at the speed of light.”

The findings were detailed in the journal Science On 16 October.
