Astrophysicists have suggested that dark matter around the planets of the solar system takes the form of long hair. Article about this accepted for publication in the Astrophysical Journal, and briefing on the study, said in a NASA press release.
Dark matter – a hypothetical form of matter that does not emit electromagnetic radiation and do not directly interact with him, which is why it is impossible to direct observation of it. At the same time, it is about 27 percent of all matter and energy in the universe.
Back in the 1990s, scientists have calculated that dark matter must form a fine-grained flow of particles moving at the same speed in orbit galaxies. When approaching the Earth, as calculated prez Gary of the Jet Propulsion Laboratory of NASA accelerate the particles are focused on super dense fiber, or hairs.
Unlike conventional, dark matter easily passes through the Earth. But, according to calculations Prez, it is the attraction of the planet deforms the flow of particles, transforming it into a narrow and dense hair.
These hairs have both roots particles with higher concentrations, up to a billion times higher than the average, and tips. Preez believes that the roots of the hair of dark matter are about a million kilometers from the Earth’s surface, and the tips – two million. When passing through the core of the Jupiter hair, dark matter should form a more roots – almost a trillion times higher than in the normal flow. If we pinpoint the location of the roots, it can be sent to the probe, which will gather a lot of information about dark matter, said Prez.
Finally, an astrophysicist conducted simulations showed that the variations of density of matter inside the Earth between the core, mantle and crust should be reflected in the structure of the hair, creating in them the characteristic curves. If scientists can gain access to this information, they will build a geological map of the heavenly bodies of dark matter and even to assess the depth of under-ice oceans on the moons of Saturn and Jupiter.
