*Question* What is the concept of quantum entanglement and how does it challenge our understanding of particle interactions? *Answer* Quantum entanglement is a phenomenon where two or more particles become linked in such a way that the state of one particle is directly correlated with the state of the other, no matter the distance between them. This challenges our understanding of particle interactions because it suggests that particles can communicate instantaneously, defying classical notions of cause and effect. https://whatsapp.com/channel/0029VaEF4IL7DAWtD6Na5Y3E
