Aspect Experiment

The Aspect experiment was a key scientific test conducted in the 1980s to explore the nature of quantum entanglement, where particles become linked such that the state of one instantly influences the other, regardless of distance. Physicists used highly precise measurements on entangled photons separated by long distances to see if their behavior followed quantum mechanics' predictions or if some "hidden" variables existed. The results showed correlations matching quantum theory, suggesting that nature doesn't consider hidden variables and that entanglement involves an instant connection that defies classical ideas of locality, deeply impacting our understanding of the fundamental behavior of particles.
