WASHINGTON, July 2. New calculation methods so-called “viscosity” of the universe show that the universe is likely to end its existence during the so-called “big gap” – the destruction of the entire matter by the mysterious dark energy, cosmologists say.
“It is possible, but it is unlikely that the phenomenon of the cosmological viscosity is responsible for all the processes that we associate with the fact that the universe is expanding with acceleration. But more likely is that it simply helps accelerate the growth of the dark energy of the universe. If this is so, then we will be able to use the data viscosity to clarify and explore its nature, “- said Marcelo Diskontsi from Vanderbilt University in Nashville (USA).
As Diskontsi explains, it is not about the usual viscosity characteristic of the toothpaste and other everyday liquids, and on her particular cosmological “cousin”, which describes how a particular gas or liquid resist compression or stretching. This property of matter is almost not interesting to us in everyday life, such as water and other liquids are considered incompressible physicists for ease of calculation.
On the other hand, this form of toughness is a big headache for cosmologists, as it prevents Modelling of the universe and study the processes of growth and evolution, according to RIA Novosti.
The fact is that if a compressed liquid to disperse the near-light speed, then under certain conditions, part of it can move faster than the speed of light, it is impossible to the point of view of modern physics. For this reason, most cosmologists ignore this phenomenon, considering it unimportant.
This solution, as shown by the formula and viscosity based on these calculations Diskontsi and his colleagues, visibly distorted predictions about what will happen to the Universe As its further growth as a result of the existence of a mysterious dark energy.
Today, popular among physicists two predictions – “Big Break” and “Big Refrigerator” likelihood of execution depends on how dark energy responds to stretching. In the first case we are talking about the total destruction of all matter in the universe, even atoms and elementary particles, and the second – on the termination of star formation and galaxy decay by reducing the density of the intergalactic medium.
Until now, scientists believed that the universe It is likely to become a “refrigerator”. New formulas authors show that the total disintegration of the universe in the “Big Break” is more likely than previously expected, due to the fact that the phenomenon of the cosmological viscosity will not slow down, but to help to expand the limits of the dark energy of the universe.
As a result, in about 22 billion years, even atoms will decay into quarks and gluons and galaxies, planets and other celestial bodies disappear even earlier.
This conclusion, as emphasized Diskontsi and his colleagues, was obtained of using abstract mathematical calculations, and they should be checked using the universe models on supercomputers. As hope of physics, their formulas to help clarify the properties of dark energy and reveal its essence.
