At the lowest temperatures in the Universe, physics gets funky.

When atoms are cooled to just above absolute zero (−459.67 degrees Fahrenheit, or-273.15 degrees Celsius), they can conduct electricity without resistance, become ’super-particle’ clouds, or flow without friction and climb up the walls of their containers.

Existence at the smallest, coldest scales is ruled by quantum statistics, which determine the behavior of bosons and fermions: the two families of fundamental particles thought to comprise every thing in the Universe.
