A minuscule height difference makes time flow slightly faster. A new quantum detector of entangled atoms catches this shift, turning a network of atomic clocks into a gravity scale. It’s a step toward probing how the quantum world and relativity mesh.
🎯 Raise an atomic clock by a single centimeter, and it’ll speed up by a billionth of a percent. That’s gravity stealing time down below.
🎬 A sci-fi nod: in Liu Cixin’s novel ‘The Remembrance of Earth’s Past’, quantum entanglement enables instant communication — a similar principle powers this network.
