Four centuries after Galileo watched objects fall in unison from a tower, physicists have carried his question into orbit — asking whether atoms governed by quantum mechanics obey the same gravitational harmony as cannonballs and moons. Aboard a space station, researchers tested the weak equivalence principle on quantum objects for the first time, probing the silent boundary where general relativity and quantum mechanics have yet to meet. The experiment does not promise a revolution, but it listens carefully at the threshold of one.
