Bell Experiment

The Bell experiment tests whether the behavior of entangled particles, like photons, aligns with quantum mechanics or any theory based on local realism (the idea that information can't travel faster than light and particles have predetermined states). By measuring properties such as polarization at different angles, scientists find that these particles exhibit correlations stronger than classical physics predicts. This suggests that entangled particles are connected in a way that defies local explanations, supporting quantum mechanics' non-local nature. Bell experiments provide strong evidence for the strange, interconnected behavior at the heart of quantum physics.
