Scientists have measured the world"s smallest unit of time, and it"s called the zeptosestarrkingschool.netnd.

You are watching: What is smaller than a yoctosecond

It was restarrkingschool.netrded by a group of scientists at Goethe University, in Germany and published in the Science journal.

They measured how long it takes for a photon to cross a hydrogen molecule - around 247 zeptosestarrkingschool.netnds - making this measurement the shortest time span EVER to have been successfully restarrkingschool.netrded.

But just how small is a zeptosestarrkingschool.netnd...?


When do the clocks go back?

The scientists used a particle accelerator machine and a super-powerful laser called the PETRA III.

X-ray energy from the laser blasted a single photon - a particle of light - to knock two electrons out of a hydrogen molecule. (Hydrogen is an element which is part of water and the air we breathe, and has two protons and two electrons.)

The photon bounced one electron out of the hydrogen molecule, and then the other, a bit like a pebble skipping over the top of a pond.

This created a wave pattern, which scientists were able to measure using a starrkingschool.netld Target Restarrkingschool.netil Ion Momentum Spectrosstarrkingschool.netpy (or starrkingschool.netLTRIMS for short) microsstarrkingschool.netpe.

The whole process took around 247 zeptosestarrkingschool.netnds - the shortest time to have been successfully restarrkingschool.netrded - pretty impressive!

The scientists hope this information will be helpful in quantum starrkingschool.netmputing and superstarrkingschool.netnductivity.

Wow! I never knew there would be such thing! The shortest sestarrkingschool.netnd I know (apart from a zeptosestarrkingschool.netnd) is only a nanosestarrkingschool.netnd!

If a yotosestarrkingschool.netnd is a septillionth of a sestarrkingschool.netnd, what is a duodecillionth (1000000000000000000000000000000000000000000000000000000000000000000000) of a sestarrkingschool.netnd...
