Pardon my naivete here. In a quantum system, it seems that even a few photons from the environment can decohere the entangled particles in the system in a trillion trillionth of a second ( or faster).
But surely one decoherence is not final. As other photons interact with the system, does decoherence keep happening? It is sometimes depicted in pop physics books as like a movie, with a succesion of frames ( or successive decoherences) continually creating the classical universe. Is this clumsy metaphor in any way accurate?
