Astronomers, cosmologists and theoretical physicists call dark matter hypothetical form of matter that does not emit electromagnetic radiation and also does not interact directly with him. Due to this property, direct observation of this substance considered impossible.
The conclusions about the existence of dark matter were made on the basis of numerous indirect signs of the behavior of space objects and by gravitational effects created by these objects. The study the nature of dark matter, according to many scientists, will allow science answer many questions regarding the emergence of the universe.

The universe is believed to have originated 13.8 billion years ago in the result of the Big Bang and has since been expanding continuously. About this is evidenced by the famous Hubble law, according to which further away from us is an astronomical object, the more significant its relative speed. Thanks to this, astronomers concluded that all things originated in a small vanishing point.
In the second half of the last century, experts started talking about invisible dark matter, as they lacked something for explanations of the motion of stars. Scientists have concluded that dark matter makes up about 27 percent of our total mass-energy The universe. For comparison, ordinary matter is only 5 percent of it.
Watching in the nineties explosions of white dwarfs in double stars, experts concluded that there is a third component, – the so-called dark energy of about 68 percent space and is responsible for accelerating the expansion of the universe.

A team of American and Hungarian researchers did the other day potentially sensational statement, reporting that the mysterious dark energy may not exist at all.
According to scientists, any traditional model of cosmology ignores the structure of the universe because it implies that matter in space have the same density. In his research experts cast aside the postulate of uniform distribution of ordinary and dark matter, assuming that in The universe has a kind of channels filled with emptiness. On the Based on this assumption, Americans and Hungarians modeled a new computer model of the expansion of the universe.
It turned out that the Universe is really expanding nonuniformly, however, the acceleration of this process in certain places is not associated with dark energy, but with lots of empty space. AND such a void should occupy just about 68 percent of the whole universe.
If this hypothesis is confirmed, then it can change our understanding of the model of the world, and therefore affect the study its processes, in particular, will force to review some laws physics.
