Quantum Entanglement Experiment: Ghosts of Time Travel?

This article delves into the delayed-choice quantum eraser experiment conducted by Kim et al. in 1999. The experiment seemingly demonstrates that photons can influence their past behavior through quantum entanglement, sparking debate about time travel. The author provides a detailed analysis, arguing that the results don't support backward time travel but stem from a misunderstanding of the probabilistic nature of light waves. The article emphasizes that photons always travel as waves, and the apparent particle behavior is a result of localized energy manifestations on the wavefront. The seemingly paradoxical results are explained as stemming from a lack of understanding of probability and wave interference. The author ultimately refutes the concept of wave-particle duality, arguing it's an illusion created by differences in observation methods.
