hidden variables theory

Hidden variables theory is an alternative theory of quantum mechanics developed by David Bohm. It suggests that the selection of a quantum state at the point of observation (commonly called "collapse of the wave function") is not random, but rather guided by real physical processes. He theorized that a pilot wave called the quantum potential emerges from a deeper, unobservable domain and guides the observed behavior of particles. Later Bohm identified the deeper level of reality as the "implicate order."
