Taking the approach to the so-called cosmological bulk viscosity, which is a determining factor in the equation of state of the universe, physicists have determined that can happen irreparable.
It is estimated that 22 billion years later, humanity, the planet Earth, the solar system and the universe as a whole, will cease to exist as a result of the Big Bang.
The results of their research are published in the journal Physical Review, as well as online at Vanderbilt University.
The bulk viscosity appears in the compressed gases and liquids, and little studied by researchers. The experts took as a basis the universe, which is a space filled with fluid, which moves to near-light speed. With this formulation, it is possible to predict the “behavior” of the universe and the development in the future.
In the event that it has a uniform (independent of location) and isotropic (when properties do not depend on the direction) expansion peculiar development of the universe at the moment of its state equation is defined as the ratio of the pressure of dark energy to the density of this energy is expressed in a special unit system parameter w.
The value of this indicator defines the evolution of the universe. Scientists do not know what size is currently setting w, but if it is less than “-1″, the Big Bang theory would be justified.
In this case, the universe will die as a result of rapid and uncontrolled expansion, leading to the disintegration of matter. At the same time, experts note that the observer can see the collapse of the matter up to the extent of applicability of the physical laws relating to the elementary particles.
