Currently, the popular scientific literature on cosmology, and increasingly mysterious glimpses of the concept – "dark matter", "dark energy". Learn more about this topic with the insights from Edward Minskoff. Part of the scientific community is busy searching for these wonderful things, and think that is about to find them really! But maybe it's easier and you should not look for what is not? A thought experiment: at the bottom of a large empty box in its center, put a handful of pebbles and gently shake box. O wonder! Pebbles from creeping cents a box away from each other. Maybe it also is with the galaxies and in all "fault" accident? In modern cosmology adopted a homogeneous isotropic model of transient hot universe. This model is confirmed by Hubble astronomer open the effect of "divergence" of the galaxies according to the law v = H r, (1) 1: v – velocity Removal of extragalactic objects; H – Hubble constant; r – the distance between the extragalactic objects. However, on the mechanism of this "recession" undecided at the moment is not produced. It is unclear What are the forces that cause expansion of the universe affect its gravitational contraction. In 2, 3, 4, 5 associated with the expansion of the Universe, "dark energy" of unknown origin, but here there is an additional question of whether "Dark matter" which affects the dynamics of galaxies, and greatly superior to the mass of ordinary matter. Is it possible explanation of the "divergence" of galaxies without the "multiplication of entities", ie the introduction of the reality of "dark energy"? Consider the behavior of the parts of the universe, as the probability of a system containing a set of objects, performing a random movement in space.

While in Russia, Ukraine, Greece, the U.S. continues to rage major forest fires, other regions of Earth fills the big water. Large forest fires are raging in Russia over an area of 348.1 hectares in Trans-Baikal region, the forest is burning in six municipalities. And the area of forest fires, unfortunately, continue only increase. Since the beginning of fire risk period 1000 recorded 125 forest fires in area 37 000 799 hectares. Chita forest protection air base conducts regular aerial reconnaissance forest fire situation in Chita, and Baleyskom Sretensky areas. Ukraine also covered the forest fires. Large pockets ignition observed in seven areas.
In Chernihiv region covered by the fire were 350 ha of land. Try to put it out with 850 people using 74 units of fire and special equipment, including fire-AN-32P. In Kharkiv region area of fire up to 500 hectares. Wood burns in Dnipropetrovsk, Poltava, Lugansk and Kherson regions and Crimea. Fortunately, no victims and survivors.
But in China, Nepal and West Africa, other element – the flood. Three people were killed and more than 1.3 million affected by the strong rains in tsentralnokitayskoy Hubei Province. In some areas of disaster in four days received more than 200 millimeters of precipitation. Triggered by rainfall floods and mudslides have destroyed thousands of homes 1.3, destroyed 115 hectares of farmland. In Nepal, over 25 thousand people fled their homes because of floods that swept the eastern areas of the country along the River Kosi. The disaster caused by prolonged rains which have led to overflow of the river bed.
