(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 ...

Absolute zero is often thought to be the coldest temperature possible. But now researchers show they can achieve even lower temperatures for a strange realm of "negative temperatures." Oddly, another ...

Absolute zero is the temperature (-273.15C) at which all motion in matter stops and is thought to be unreachable. But recent experiments using ultracold atoms have measured temperatures that are, in ...

There’s a whole mirror world of negative temperatures reaching from minus infinity to absolute zero – now we’re plumbing those depths for real DEFINING a temperature scale is easy. Fire is hot, ice is ...

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 ...

Physicists don’t tend to use universal language freely, so since Lord Kelvin dubbed the base measure of his temperature scale “absolute zero,” that should be a sign that there is reason for the ...

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 ...
