Self-measurement of the quantum universe leads to emergence of time

The dynamics of the quantum universe under self-measurement is investigated in the framework of the path-integral approach to the quantum theory of continuous measurements. It is shown that the picture of time evolution of the quantum universe naturally emerges as a result of its self-measurement. T...

Description
Summary:The dynamics of the quantum universe under self-measurement is investigated in the framework of the path-integral approach to the quantum theory of continuous measurements. It is shown that the picture of time evolution of the quantum universe naturally emerges as a result of its self-measurement. The Wheeler-DeWitt dynamics maintains for small times.
