Entanglement

Entanglement is a quantum phenomenon where two or more particles become connected such that the state of one instantly influences the state of the other, regardless of the distance between them. When particles are entangled, measuring a property (like spin or polarization) of one particle immediately determines the corresponding property of its partner, even if they are light-years apart. This correlation defies classical intuition but is well-supported by experimental evidence, highlighting the non-local nature of quantum mechanics and challenging traditional ideas about how objects relate across space.
