    Absolute Zero is supposed to be the absolute coldest temperature there is. You just can't go any lower than that. Pretty simple, right?

    Well, apparently no one defined "absolute" to a group of German scientists, who took on the age-old question of "How cool is cool?" for themselves.

    Huh. Looks like Lord Kelvin's getting the cold(er) shoulder.

    Sure, it's only a few billionths we're talking about here, but as far as "temperature limbo" goes, that's still an amazing breakthrough. They shimmied below a threshold that was supposed to be absolute, after all.

    This isn't some useless endeavor, either. The techniques and results could be turned towards creating new types of matter in the laboratory, and could theoretically play a role in the development of quantum devices. Plus, since the behavior of sub-absolute zero gas seems to mimic that of so-called "dark energy", it could help us better understand this mysterious force.

    Needless to say, these guys shouldn't have their assets frozen anytime soon.

    So the next time you're caught out in the cold, freezing and miserable, just remember that it could always be colder; science is making sure of that.

    Hey ladies? What's cooler than being cool?

    ICE COLD.

    Yes.
    Gahars surely used his pun limit up on this one.

    Well, sometimes getting less than zero is a good thing.

    That's pretty cool. In fact, that's cooler than absolute zero.

    Very interesting and impressive achievement.

    Something of note for everyone making "cool" and "cold" jokes though; the absolute negative temperature is actually hotter than an infinite positive temperature. It's called negative because it's an inversion of the positive Boltzmann distribution. So your puns are invalid :P

    I'm not sure what the story is about anymore, but there's glass and shattered things all around my desk and my forehead is bleeding.

    I blame puns.

    This is really neat, I love when scientists shatter what was thought to be certain.

    how do they measure something below absolute zero?

    My guess is it has something to do with the signature above you :o

    What I want to know is how do you get below absolute zero.

    Since absolute zero is the absence of any molecular motion.

    To put it another way, its like saying a stopped car is now moving even slower than stopped.

    I think we are being trolled by scientists... lol

    For all the people asking, the article explains a bit more on how the scientists accomplished this feat - it was just excised from the post to fit in more puns make the quote more concise.

    @The comments about negative temperature, well quite simply:

    Essentially negative temperature here refers to a thermodynamic property of the system that is perhaps divergent from the ordinary definition in this case. Temperature here defines therate at which entropy increases as thermal energy is added to the system. Ergo, negative temperature relates to a state where adding energy at least incrementally might decreasethe entropy of the system.

    So.. yeah...:unsure:
