On the absolute temperature scale, which is used by physicists and is also called the Kelvin scale, it is not possible to go below zero – at least not in the sense of getting colder than zero kelvin.

Temperature is typically thought of as the average energy of individual atoms or molecules within a given collection. For atoms of similar mass, this "kinetic temperature" would basically be their ...

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 ...

This press release is available in German. 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 ...

The temperature of absolute zero is 459.67 degrees below zero Fahrenheit, the lowest temperature possible. It is the temperature at which no molecular motion exists and it represents the total absence ...

At roughly minus 460°F, absolute zero is abysmally cold, yet at least we can imagine it. Being only a few hundred degrees below zero, it's in the realm of something we can put our minds around. This ...

Science is full of zeroes. Light has zero mass. Neutrons have zero charge. A mathematical point has zero length. Those zeroes might be unfamiliar, but they follow a consistent logic. All represent the ...
