It's hard to study quantum behavior on Earth. You can amplify the effects of quantum mechanics by zapping groups of specific atoms (Bose-Einstein condensates) with lasers that drop their temperature to near absolute zero, but that only works for fractions of a second before gravity invariably takes over. NASA's solution? Create the coldest known place in the universe. The agency just launched the Cold Atom Lab, a box that takes advantage of microgravity aboard the International Space Station to keep condensates in that ideal state for much longer.
