Free falling: Einstein's equivalence principle holds that the motion of freely-falling bodies (whether apples, oranges, or anything else) is independent of their composition. The Cold Atom Laboratory aboard the International Space Station aims to test this principle using ultracold atoms with different masses.

The motion of freely-falling bodies is independent of their composition. This is one of the foundati
