MIT's Atomic-Precision Double-Slit Experiment Proves Einstein Wrong (Again)
2025-07-30
MIT physicists have performed an idealized version of the double-slit experiment, demonstrating with atomic-level precision the wave-particle duality of light and proving Einstein incorrect on a key quantum scenario. Using individual atoms as slits and weak light beams, they controlled the information atoms received about the photon's path. The more path information obtained (particle-like behavior), the lower the interference pattern's visibility. This experiment eliminates extraneous factors from previous versions, clarifying the wave-particle duality and confirming quantum mechanical predictions. It's a stunningly precise confirmation of a fundamental quantum principle.
