Two ultra-cold atom clouds, known as Bose-Einstein condensates, become mysteriously linked when placed a hair's width apart. Their internal sound waves synchronize in a way only possible if gravity follows quantum rules, offering a powerful new path to glimpse the grainy fabric of spacetime.

A new theoretical work unites quantum mechanics and general relativity, showing that two parallel atomic lasers, unperturbed in the classical world, begin to diverge under the influence of quantum fluctuations of spacetime. Vacuum tremors of the metric give rise to an irreducible spread of trajector
