They should coordinate. Like an orchestra section where each musician can hear the others, the atoms would sync up and release their energy in a single, blazing burst: brighter, faster, and more directional than if each atom acted alone. He called it superradiance.</p> <p>The theory was beautiful. Testing it took decades. And now, 72 years later, physicists in France have done something nobody had managed before: they took a picture of the exact spatial pattern of that collective emission and found it looked nothing like what the textbooks predicted.</p>
