NASA scientists have successfully created the coldest spot in the known universe, supercooling atoms aboard the International Space Station in an effort to test a theory put forth by Albert Einstein but never proven.
The space agency installed a cold atom lab, a box the size of a small refrigerator, equipped with lasers used to manipulate atoms in microgravity in May. In July, they were able to create clouds of ultracold atoms – called Bose-Einstein condensates – that are described as a fifth state of matter that behave differently than solids, liquids, gasses and plasmas for the first time in orbit.
