Researchers at IPhT (CEA, CNRS) and the Universitat Autònoma de Barcelona have shown that gravity—and with it, supersymmetry—emerge as logical necessities whenever a massive spin-3/2 particle exists ...

In quantum physics, objects can exist in multiple states at the same time—a phenomenon known as quantum superposition, where ...
