While GeekExtreme still holds the title of being so cool we run at 0 Kelvin, some scientists have managed to come close to actually OBTAINING 0 Kelvin. At a mere 1 billionth of a degree above Kelvin, they have cooled a sodium gas to a temperature never before recorded.

At absolute zero (-273º Celsius or -460º Fahrenheit), all motion stops, except for tiny atomic vibrations, since the cooling process has extracted all energy from the particles. By improving cooling methods, scientists have succeeded in getting closer to absolute zero.
