The quantum graininess of space slows galaxy formation but amplifies gravitational waves.

A minimum length in quantum gravity alters galaxy growth and amplifies gravitational waves from the early universe. Future observatories will put this to the test.

🎯 If an atom were enlarged to the size of the entire observable universe, the Planck length would be merely the height of an average tree.

🎬 Grainy space resembles the 'quantum foam' of science fiction — the basis for wormholes and time travel.
