Russian scientists know where the "dark matter" is hidden

US-Russian scientific group announced a new theory on the composition and the place where in the Universe is "dark matter." This substance does not spread around electromagnetic radiation and is therefore far elusive for instrument. Scientists have so far only assumed where the missing group of mysterious matter. "We know where to look, - said Russian-American group of physicists. - It creates a disk around the galaxies, stars and planets. "

See the invisible, to know the unknowable - under that banner now for US-Russian team of scientists at Harvard University in the United States. In terms of "dark matter" now has more puzzles and assumptions rather than established facts. Until now it was thought that the particles of the substance almost no way are related to each other. The Scientific Group under the direction of Andrew Katz in the journal Physical Review Letters disprove this hypothesis. Particles of "dark matter" must be different - not only passive, but active. There are "dark" protons and electrons, which interact and form a "dark" atoms, scientists believe.

Nature mysterious substance may look like an ordinary nature, says Katz. Probably each effect does not take place only at the subatomic level, but also among the "dark" atoms.

The activities and the mutual influence of particles of "dark matter," the group began to speak after the analysis of gravitational effects. Judging by them, "dark matter" forms around the disks of galaxies, stars and planets. These groups elusive substances may arise from the interplay between the "dark" of protons and electrons. They cause loss of energy and particles should then start to move slowly, explains Andrei Katz. This is exactly what leads to their collection and forming a flat disk around the galaxy. This happens with ordinary matter.


Physicists also assumed that the "dark" atoms could form a "dark" plasma, whose pulsations influence on the young Universe. Now the mysterious particles affect the cosmic objects.

"The theory of" dark "disc is a new step in the understanding of the history of the Universe," - commented the astronomer from the California Institute of Technology Sean Carroll (Sean Carroll).

Gravitational effects caused by the drive of "dark matter" to record the cosmic telescope "Gaia" believes Carroll. This super powerful telescope of the European Space Agency will be carried into orbit 2013th , and draw up a detailed map of the galaxy. Scientists are hoping to get a confirmation of his theory.
