Cosmological Quantum Jump Dynamics II. The Retrodictive Universe

TL;DR

This paper develops a deterministic retrodictive universe model that explains the arrow of time and entropy increase, linking quantum dynamics with cosmological evolution.

Contribution

It introduces a novel retrodictive universe framework with deterministic past dynamics and indeterministic future dynamics, connecting quantum mechanics and cosmology.

Findings

Retrodictive universe model constructed

Arrow of time arises naturally in the model

Future entropy increases as in standard quantum theory

Abstract

This paper is a continuation of the paper gr-qc/0203045 and is devoted to the problem of the arrow of time. A deterministic past-directed dynamics is constructed, which results in the retrodictive universe. A future-directed dynamics of the latter is indeterministic and reproduces standard probabilistic quantum dynamics. The arrow of time is inherent in the retrodictive universe as well as a future-directed increase of informational entropy.
