Illusiveness of the Problem of Time

S. L. Cherkas and V. L. Kalashnikov

The essay is devoted to the problem of time in the context of quantum cosmology, which acquires a philosophical level to date. At an example of the minisuperspace model, we show that this problem is illusive because it does not prevent calculating the mean values of the operators over the quantum state of the universe. Contrariwise, the different approaches to the description of these time-dependent mean values give similar results.

Key words: general relativity, classical cosmology, quantum cosmology
