WORLD'S SMALLEST TEMPERATURE
THE LONGEST LIST OF THE LONGEST STUFF AT THE LONGEST DOMAIN NAME AT LONG LAST

What is the world's smallest temperature?


How cold can it get?

The coldest it can get is absolute zero which is 0 Kelvins, −273.15 C or −459.67 F at which point all measurable motion of atoms would cease. Absolute zero has never been documented, but we'll show you some fun facts about smallest temperatures.

The coldest recorded temperature on Earth was −129 F in 1983 at the Russian Base Vostok in Antarctica.

The coldest naturally occurring place is space which is about 3 Kelvin or −454 F.

The coldest known part of space is The Boomerang Nebula which comes in at a balmy 1 Kelvin or −457.6 F.

Scientist are experimenting with Bose-Einstein condensation where atoms slow down to an almost complete stop and create a blobby mass of atoms. For this it has to be very, very cold.

Using laser light scientists can cool atoms to 1/10,000 Kelvin, but that's still not cold enough.

They then apply evaporative cooling which brings the atoms down to the world's smallest temperature, 50/1,000,000,000 K (50/billionths Kelvin) and end up with their atom blob.
