Right now, as I type this sentence, Earth's Northern Hemisphere is tilted away from the bright ball of light that is the Sun, and it’s cold here (relatively speaking). Humans have long recorded and ...

(Nanowerk News) What is normal to most people in winter has so far been impossible in physics: a minus temperature. On the Celsius scale minus temperatures are only surprising in summer. On the ...

In August 2021, a German research team announced that they had succeeded in an experiment to cool a substance to '38 picokelvin (38 degrees 1 trillion)', which is very close to -273.15 degrees Celsius ...

Nothing is colder than absolute zero, so it seems nonsensical to talk about negative temperature – but now there is a substance that must have just that. The revelation could shake up our ideas about ...

Over the past decades, researchers have made significant progress in cooling objects closer to absolute zero, the temperature at which all molecular motion reaches its minimum. This has allowed them ...
