👉 Lifetimes are a type of measurement used in physics, particularly in quantum mechanics and theoretical physics. The concept is based on the idea that particles can exist for an infinite number of time periods without experiencing any observable effects due to their nature as a wave-like particle. In terms of quantum theory, lifetimes play a crucial role because they are essential for the understanding of quantum entanglement, the phenomenon where two or more particles become connected in such a way that the state of one is dependent
