Now experimental physicists
at MIT have successfully cooled molecules in a gas of sodium potassium (NaK) to a temperature of 500
nanokelvins — just a hair above absolute zero, and over a million times colder than interstellar space.
At 30 microkelvins, the atmosphere would shrink to a mere millimeter, and at 30 nanokelvins, the height of the atmosphere would be one micron, or a hundred times less than the thickness of the human hai
