On the Curiously Retro-causal Effects of Quantum State Reduction in Quantum Reality

Journal article

It has been argued that quantum state reduction is a gravitational effect. However, to make sense of it one needs to distinguish “Quantum Reality” from the more familiar “Classical Reality”. This notion of quantum reality is developed here, indicating its curious relation to the normal flow of time, most strikingly in the Einstein-Podolski-Rosen type of phenomena.
