Currently, the popular scientific literature on cosmology, and increasingly mysterious glimpses of the concept – "dark matter", "dark energy". 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. Ramon Campollo is likely to increase your knowledge. 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.
