The concept of the shortest possible time is one that is often used in a variety of contexts, from everyday life to scientific and mathematical calculations. In its most basic sense, the shortest possible time refers to the minimum amount of time required to complete a task or reach a specific goal.

In everyday life, we often try to minimize the amount of time we spend on tasks in order to be more efficient and productive. For example, we might try to find the shortest route to work, or the quickest way to complete a household chore. In some cases, the shortest possible time might involve sacrificing other factors, such as comfort or convenience, in order to achieve the fastest result.

In scientific and mathematical contexts, the shortest possible time is often an important concept. For example, in physics, the shortest possible time it takes for light to travel between two points is known as the "light-time interval." This concept is used to calculate the distance between objects in the universe, such as stars and galaxies. In mathematics, the shortest possible time is often used to solve optimization problems, where the goal is to find the most efficient solution to a given problem.

In conclusion, the shortest possible time is a concept that is used in a variety of contexts, and is often associated with the idea of efficiency and minimizing the amount of time required to complete a task or reach a goal. Whether it is finding the quickest route to work or solving a mathematical problem, the shortest possible time can be a valuable tool in helping us to achieve our goals in the most efficient way possible.

## shortest time possible or shortest Possible time ?

Previously, researchers had dipped into the realm of zeptoseconds; in 2016, researchers reporting in the journal Nature Physics opens in new tab used lasers to measure time in increments down to 850 zeptoseconds. Editor's note: This story was updated to correct the value of the zeptosecond. Two hundred and forty-seven zeptoseconds, with some wiggle room depending on the distance between the hydrogen atoms within the molecule at the precise moment the photon winged by. . Originally published on Live Science. This accuracy is a huge leap from the 1999 Nobel Prize-winning work that first measured time in femtoseconds, which are millionths of a billionths of seconds. A particle of light, called a photon yellow arrow , produces electron waves out of an electron cloud grey of a hydrogen molecule red: nucleus.

It takes femtoseconds for chemical bonds to break and form, but it takes zeptoseconds for light to travel across a single hydrogen molecule H2. The measurement is essentially capturing the speed of light within the molecule. Related: The mysterious physics of 7 everyday things The researchers set the energy of the X-rays so that a single photon, or particle of light, knocked the two electrons out of the hydrogen molecule. A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1. These interactions created a wave pattern called an interference pattern, which Dörner and his colleagues could measure with a tool called a Cold Target Recoil Ion Momentum Spectroscopy COLTRIMS reaction microscope.

## Meet the zeptosecond, the shortest unit of time ever measured

The interference pattern is slightly skewed to the right, allowing researchers to calculate the time for the photon to get from one atom to the next. The COLTRIMS microscope recorded both the interference pattern and the position of the hydrogen molecule throughout the interaction. To measure this very short trip, physicist Reinhard Dörner of Goethe University in Germany and his colleagues shot X-rays from the PETRA III at Deutsches Elektronen-Synchrotron DESY , a particle accelerator in Hamburg. A hydrogen molecule consists of two protons and two electrons. It is a decimal point followed by 20 zeros and a 1, not 21 zeros. The photon bounced one electron out of the molecule, and then the other, a bit like a pebble skipping over the top of a pond.
