"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.

Thank you for the link. I’m very much interested in science and spent most of my working life doing failure analysis ... Navy day’s, and then after college ... defense industry years.
