Wissenschaftler beobachten zum ersten Mal ein Antimaterie-„Atom“, das sich wie eine Welle verhält – Ein bizarres Antimaterie-„Atom“ hat gerade bewiesen, dass es sich wie eine Welle verhalten kann – und öffnet damit die Tür für neue Quanten- und Schwerkraftexperimente.

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 wave-like interference in positronium, an exotic “atom” made of an electron and its antimatter partner, a positron. This breakthrough not only strengthens the weird reality of quantum mechanics but also opens the door to new experiments involving antimatter, including the possibility of testing how gravity affects it—something never directly measured before.
