Another article on quantum behavior of atoms in a new study about to be done in space:

"The Cold Atom Lab (CAL) will create a spot aboard the International Space Station 10 billion times colder than the vacuum of space.

"NASA is poised to "freeze" atoms in their tracks with lasers, creating the coldest spot in the universe — less than one-billionth of a degree above absolute zero, the lowest possible temperature — on board the International Space Station (ISS).

At that temperature, atoms slow down so much that they begin to enter the same quantum state, exhibiting the same amount of energy as one another, NASA representatives explained.

"NASA is poised to "freeze" atoms in their tracks with lasers, creating the coldest spot in the universe — less than one-billionth of a degree above absolute zero, the lowest possible temperature — on board the International Space Station (ISS).

"The Cold Atom Laboratory (CAL) is a compact instrument about the size of a beer cooler, and it uses lasers to generate a super-cooled environment 10 billion times colder than the vacuum of space. It's so cold inside CAL that atoms become nearly motionless; CAL then uses magnets to trap the slowed atoms so that scientists can observe their movements and how they interact.

"The vacuum of space is cold, about minus 455 degrees Fahrenheit (minus 270.55 degrees Celsius). But temperatures inside CAL will be even colder: nearly absolute zero (absolute zero is minus 459.67 degrees F, or minus 273.15 degrees C).

"At that temperature, atoms slow down so much that they begin to enter the same quantum state, exhibiting the same amount of energy as one another, NASA representatives explained. Their behavior becomes more wavelike, and they start to synchronize like a line of dancers — a phenomenon known as a Bose-Einstein condensate (BEC).

"And in the microgravity of the ISS, atoms are expected to retain this state of matter for up to 10 seconds, offering researchers the possibility of observing quantum behavior never seen before, according to a CAL mission description. "
