Entanglement Builds Space-Time, Linking Quantumness to Gravity

Physicists are increasingly finding that entanglement doesn’t just link quantum particles; it may actually build the very fabric of space-time. Building on John Archibald Wheeler’s observation that “space acts on matter, telling it how to move,” and “in turn, matter reacts back on space, telling it how to curve,” researchers have struggled to reconcile this relationship at the quantum level. Now, multiple teams have identified a quantum property called “magic” that appears to give space-time its bendiness, allowing matter to influence its curvature. John Preskill, a physicist at the California Institute of Technology, said that without this property, things would be too simple, and quantum space-time is not that simple. This discovery offers a potential pathway toward understanding gravity as a quantum phenomenon and resolving long-standing conflicts between general relativity and quantum physics. In holographic theories, physicists may have…
