QUANTUM TIME SYMMETRY. “Space-time is assumed to exist as an average property, but the quantum interactions do not need to refer to space-time properties, and in case of a suppression of the interactions, the average does not need to display the properties it otherwise has. Supporting this consideration is the similarities of space-time with thermodynamics.”
