Jan 19, 2004 · Absolute zero corresponds to –273 degrees Celsius and –460 degrees Fahrenheit. Cooling an object requires extracting energy from it and depositing it somewhere else.
Jun 26, 2024 · Today, atomic physicists like myself use a technique partly pioneered at NIST called laser cooling, which uses lasers to cool clouds of between 100,000 and 1 billion atoms to temperatures of about 100 microkelvin. This temperature is 1/10,000th of a degree Celsius above absolute zero.

Absolute zero is the lowest possible temperature, right? Not quite — physicists have recently developed a negative temperature system by creating an atomic gas that exists at a few billionths of a Kelvin below zero.
Jan 4, 2013 · Summary: 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...
Jan 4, 2013 · 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.
If you're concerned about why zero Kelvin is the lowest possible temperature (a.k.a. absolute zero), it's simply because scientists have decided to make the Kelvin scale an absolute temperature scale - that means the lowest possible temperature, by definition, is zero Kelvin.
