From the internet, we have ...

Absolute zero is ... "the temperature at which matter has no heat and its molecules are completely still; theoretically, the lowest possible temperature: equal to about -273.16°C or about -459.69°F or 0°K"

"While scientists can not fully achieve a state of “zero” heat energy in a substance, they have made great advancements in achieving temperatures ever closer to absolute zero In 1994, the NIST achieved a record cold temperature of 700 nK (billionths of a kelvin). In 2003, researchers at MIT eclipsed this with a new record of 450 pK (0.45 nK).

...which means they haven't yet achieved a state where molecules are completely still. I know I'm picking at nits but I find it interesting...as I hope you do.
