Physicists have measured the shortest span of time ever. It's 0.000000000000000000247 second, also known as 247 zeptoseconds. And this period is how it takes a single particle of light to pass through a molecule of hydrogen.

What is the fastest time period?
scientists have now clocked the shortest time measurement ever, expressed as 247 'zeptoseconds', by observing the time it took for a photon (a particle of light) to travel across a hydrogen molecule. in this ultrafast timescale, a zeptosecond is equal to a trillionth of a billionth of a second.
How fast is a zeptosecond?
A zeptosecond is a trillionth of a billionth of a second (10-21 seconds). In 1999, the Egyptian chemist Ahmed Zewail received the Nobel Prize for measuring the speed at which molecules change their shape.
What is the shortest interval called?
An interval is the distance in pitch between two notes. The smallest interval is a semitone. This is the distance between, for example, C and C#.
Who discovered zeptosecond?
Earlier, a study was carried out in 1999 which led to the discovery of the femtosecond which equals one quadrillionth of a second. Egyptian scientist Ahmed Zewail, discovered this unit of time while measuring the speed at which molecules change their shape. He was awarded with the Nobel Prize.
What is faster then a zeptosecond?
The only unit of time shorter than a zeptosecond is a yoctosecond, and Planck time. A yoctosecond (ys) is a septillionth of a second. And how do you figure out Planck time?! Divide the minuscule Planck length by the speed of light (which is pretty big) and you get a really tiny unit of time - the Planck time!
Whats faster than a second?
Femtosecond is one quadrillionth of a second. Picosecond is one trillionth of a second. Nanosecond is one billionth of a second. Microsecond is one millionth of a second.
How much is a yoctosecond?
A yoctosecond (ys) is a septillionth of a second or 10–24 s*. Yocto comes from the Latin/Greek word octo/οκτώ, meaning "eight", because it is equal to 1000−8. Yocto is the smallest official SI prefix. A yoctosecond is the shortest lifetime measured, so far.
How many Zeptoseconds are in a second?
A zeptosecond is a trillionth of a billionth of a second, or a decimal point followed by 20 zeroes and a 1. Previously, researchers had dipped into the realm of zeptoseconds; in 2016, researchers reporting in the journal Nature Physics used lasers to measure time in increments down to 850 zeptoseconds.
What happens in a yoctosecond?
One yoctosecond is one trillionth of a trillionth of a second (10–24 s) and is comparable to the time it takes light to cross an atomic nucleus. Indeed, the researchers say that such pulses could be used to study the ultrafast processes taking place inside nuclei.
What is the longest unit of time?
The largest unit is the supereon, composed of eons. Eons are divided into eras, which are in turn divided into periods, epochs and ages.
What is the shortest distance between two tones?
A half step, or semitone, is the smallest interval between notes in Western music. Notes that are directly next to each other—such as E and F, or A sharp and B—are a half step apart. Two half steps equal one whole step.
How long is a jiffy?
For physicists, a jiffy is how long light takes to travel a distance of one femtometre, which is a millionth of a millionth of a millimetre. That means that there are about three hundred thousand billion billion jiffys in a second.
What is smaller than a second?
The units smaller than a second are: Milliseconds: 10-3 s. Microseconds: 10-6 s. Nanoseconds: 10-9 s.
Is a Zeptosecond faster than a attosecond?
An attosecond is 1×10−18 of a second (one quintillionth of a second). For comparison, an attosecond is to a second what a second is to about 31.71 billion years. The word "attosecond" is formed by the prefix atto and the unit second. ... An attosecond is equal to 1000 zeptoseconds, or 1⁄1000 of a femtosecond.
Why is 1 second a second?
Today, one second is defined as “9,192,631,770 periods of the radiation corresponding to the transition between the two hyperfine levels of the ground state of the cesium 133 atom”. That's a mouthful. ... When scientists moved to their new “atomic clock” in 1967, they calibrated it with his measurements.
