Quantum mechanics is the field of physics that explains how extremely small objects simultaneously have the characteristics of both particles (tiny pieces of matter) and waves (a disturbance or variation that transfers energy). Physicists call this the “wave-particle duality.”
Is a fascinating, counterintuitive phenomenon where two subatomic particles remain deeply connected, even if separated by billions of light-years. A change in one particle instantly influences the other, regardless of the distance between them.
