Yes there is action in entanglement. A particle, according to our science, does not have a definite state if it is unobserved. Thus, when it is observed, “the wave function collapses,” and instantaneously all entangled particles come out of their probability state and enter their definite state… and this occurs without respect to their spatial separation. It is spooky action at a distance. It’s more complicated than that, though. The phenomenon also occurs as if time didn’t exist. A decision made in the future of one particle will effect the entangled partner in that partners past. See the “delayed choice double slit experiment “
