Getting to absolute zero is less a matter of cooling something to 0 degrees Kelvin (-273 C or -459.6 F) than it is to designing a way to measure the temperature once you get there. The atoms of all materials at a temperature above 0 K are in incessant motion.

Absolute zero has actually never been reached, not in nature nor in the laboratory. It may well be impossible to reach absolute zero and, even if it was achieved, it might go unnoticed since there is no thermometer ... Absolute zero is really an abstract idea. Although scientists have been able to get tantalisingly close,

Frozen chips The first semiconductor chip able to clock 500GHz or above has been created by freezing it to just 5A*C above absolute zero. IBM and the Georgia Institute of Technology scientists explored the speed limits of silicon-germanium (SiGe) devices.(Brief article) (Personal Computer World)

Not until the end of the nineteenth century would a true locus of the cold become a more real destination, as Victorian scientists tried to reach absolute zero, a point they sometimes called "Ultima Thule." Likening themselves to contemporary explorers of the uncharted Arctic and Antarctic regions,

It is not possible to reach absolute zero - it is not possible in theory or in practice according to our present understanding. Gravity is an ever present influence so it will effect them.
