Delayed-Choice Quantum Eraser Experiments

Top 10 Time Travel Experiments

Delayed-Choice Quantum Eraser Experiments: These experiments challenge classical causality. A photon’s past behavior (wave or particle) seems determined by a future measurement choice, even after the photon has been detected. By “erasing” path information later, researchers can retroactively change the observed outcome. While not enabling information transfer to the past, it suggests quantum events aren’t fixed until measured, blurring time’s arrow. This doesn’t allow sending messages backward but implies time may not be linear at the quantum level. It fuels debate on retrocausality, showing that quantum mechanics permits strange temporal relationships, pushing the boundaries of how we understand cause and effect.
