Russian scientists have created a new hybrid material based on plexiglas, which will help catch the particles of dark matter. This material absorbing third-party radiation can be used to create a detector shell on the installation in the national laboratory of the Grand Sasso laboratory in Assergi, Italy. The results of scientific work were published in the Materials magazine, briefly about the study tells the publication “Popular Mechanics”.
The material contains a large number of hydrogen atoms that capture foreign background neutrons. It also consists of a rare-earth metal of the Gadolinium, which effectively absorbs thermal neutrons. It is suitable for creating a shell of target cameras filled with argon. According to physicists, hypothetical particles of dark matter, whose existence is not yet confirmed, should fly through the chambers and face argon atoms, which generates characteristic signals. The search for particle search is planned to be launched in Italy in 2025-2026.
It is known that the external areas of galaxies are rotating faster than this can be expected from the Newtonian dynamics of the visible (baryon) substance, the component of the star, planets and gas-pepped clouds. This mysterious phenomenon is explained by the existence of an unknown gravity source called dark matter.
The presence of a hidden mass in galaxies is confirmed by weak gravitational linlication, baryon acoustic oscillations and a space microwave background. However, the nelyuture of the dark matter particles is one of the main unresolved problems of cosmology, which leaves a place for alternative theories of gravity that exclude a hidden mass of cosmological models.
