The particles of light pass through the slits forming a pattern appropriate to the passage of light through the holes, but when no one is looking or there are no recording devices to record the event, the pattern obtained is completely different as if the light ignored the slits, managing to cross the barrier arbitrarily, creating a pattern. The moment the recording devices are turned on, the light particles start to behave again following the laws of physics and passing through the slits respectively. #doubleslitexperiment #quantumphysics #unifiedfield #quantummechanics
