Polarization of Vacuum

The study of the vacuum polarization phenomenon and the nature of its quantum structure is an actual problem in modern physics. Ignoring this fact often leads to erroneous interpretation of the experimental data. In quantum electrodynamics (QED), the instability of a physical vacuum is characterized by the formation of pairs of elementary particles. The article contains descriptions of experiments, that allow substantiate the quantum structure of vacuum and the reality of particles arising in a vacuum as a result of its polarization. The idea of "virtuality" of particles is connected with the inability of quantum field theory to describe the real mechanism of vacuum polarization.
