WHAT IS TIME?

Abstract

We discuss a phenomenological view on the problem of time in the context of the cosmological problem. Based on the concept of time as a force similar to gravity, created by the deformation of the past in the field of view of a modern observer, it is shown that the Universe is a binary system in which one part, hidden behind the time horizon, inevitably affects the second - the visible one. The physical content of the concept of time is the key to understanding the nature of hidden matter and the acceleration of the Universe.
