What happens when you get to absolute zero?

But scientists found that molecules at frigid temperatures just a few hundred billionths of a degree above absolute zero (?273.15°C or 0 kelvin) can still exchange atoms, forging new chemical bonds in the process, thanks to weird quantum effects that extend their reach at low temperatures.Feb 17, 2010 read more

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

If an atom could reach absolute zero, its temperature would be precisely zero, which implies an exact speed of zero. But knowing the atom's speed exactly, means we know nothing at all about its position. "There really is no physical description that allows for [an atom at]zero temperature" e-mails physicist Erik Ramberg of Fermilab. read more
