Absolute zero is supposed to be the coldest cold — 0 Kelvin, the point where atoms stop moving.

But researchers at the University of Munich say it's possible to get colder than that, an idea they've demonstrated experimentally. But what does it mean to be colder than cold? Here's the scientists' totally unhelpful explanation:

another way to look at these negative temperatures is to consider them hotter than infinity, researchers added.

Cool. Thanks, guys. Luckily, journalist Charles Q. Choi makes this strange idea make a whole lot more sense. Read his explanation at LiveScience.
