Scientists have proposed a mathematical model that combines General relativity with the effect of vacuum polarization.
Scientists have proposed a mathematical model that combines General relativity with the effect of vacuum polarization. The last is that in empty space because of Heisenberg’s uncertainty principle quantum fluctuations occur, which are born and die the vacuum “bubbles” — pair particle-antiparticle. These particles are virtual because they exist only for a very short period of time and cannot be registered by conventional devices. Thus, the appearance of particles of “emptiness” is not contrary to the law of conservation of energy.
Under external influence, for example, part of the electron electromagnetic field, virtual particle pereorientirovanija so that particles with a positive charge closer to the electron, which causes a partial screening of the electric charge. This effect can prevent the compression of the neutron star to the state of the black hole, even if its mass exceeds the limit Oppenheimer-Volkov.
Equilibrium neutron star is determined by the gravity and the pressure of degenerate gas, formed by the tightly Packed neutrons. In that case, if the gravitational attraction exceeds the repulsive force between the neutron star collapses into a black hole. The vacuum polarization creates the opportunity for the occurrence of intermediate forms between the neutron hole and neutron stars, called semiclassical relativistic star.
