In recent years much has been written and said about the physical nature of the vacuum. With some approximation, the real space, separated from each other planets, stars, galaxies, is a perfect vacuum. What we now know about its properties? From the point of view modern physics a perfect vacuum does not exist. The vacuum is an oscillating field that interacts with other fields. Already relatively weak gravitational field near the star causes distortion space, and in the presence of a strong electromagnetic field of an electron, or intranuclear forces appear in a vacuum virtual particles. They always appear in pairs – the particle-antiparticle pairs and disappear quickly, while existing in time is considerably less than the most short-lived elementary particles. Nevertheless, it is theoretically proved that the superstrong field can lift the particles from the vacuum, making them thus in a very real particles, have well-defined rest mass.
This means that the vacuum has energy, however, so slight that it can not be measured by any currently existing devices. If the vacuum is able to regenerate in substance, according to the law of conservation of energy, it should probably mean the physical destruction of a three-dimensional space with earlier this energy! Conversely, perhaps there may be processes in which the substance can be transformed into a spatial field as a result of energy dissipation. This process is even more preferable since it is accompanied by an increase in entropy of the system. Between matter and space is not, therefore, an irresistible face and they are in certain circumstances may transform into each other.
