Text 1 Quantum entanglement is a phenomenon where particles become interlinked, such that the state of one instantaneously influences the other, regardless of distance. Einstein famously derided this as 'spooky action at a distance,' skepticism rooted in his belief that nothing could travel faster than light. Text 2 Decades of experiments, most notably the Bell test experiments, have confirmed various aspects of entanglement. These findings suggest that the universe is 'non-local,' meaning spatially separated objects can be intrinsic parts of a single system.
