Abstract

Certain aspects of time physics were considered within the framework of quantum cosmology of the closed universe. Based on the general relativity we know that total energy of the closed universe is precisely equal to zero. This fact allows interpreting the creation of the closed universe as a spontaneous, causeless occurrence of respective quantum fluctuation, without any energy input. However, in such a universe the unitary evolution is “frozen”—no changes may occur, i.e. the universal cosmic time, which numbers the changes in the state of the universe, cannot exist. This conclusion is obviously contrary to the experiment. For this reason the changes observed in the closed universe may be generated solely by non-unitary, irreversible and jumpwise evolution, associated with quantum measurement, which cannot be caused by any element of reality liable to linear laws of quantum theory. Therefore, quantum cosmology does not generate a closed thinking system. In consequence, this leads to an ontology called objective idealism.
