Quantum physics overturned classical ideas by showing that matter behaves very differently at the smallest scales. One of its most surprising discoveries was wave-particle duality, the idea that ...

Quantum physics once shocked scientists by revealing that particles can behave like waves—and now, that strange behavior has been pushed even further. For the first time, researchers have observed ...

At the smallest scales of nature, the rules of the world shift in ways that can feel unsettling and beautiful at the same time. Matter no longer behaves like solid objects moving along clear paths.
