The dark components of the Universe are slowly clarified

Abstract

The dark sector of the Universe is beginning to be clarified step by step. If the dark energy is vacuum energy, then 123 orders are exactly reduced by ordinary physical processes. For many years these unexplained orders were called a crisis in physics. There was indeed a "crisis" before the introduction of the holographic principle and entropic force in physics. The vacuum energy was spent for the organization of new microstates during the entire life of the Universe, but in the initial period of its evolution the vacuum energy (78 orders) were reduced more effectively by the vacuum condensates produced by phase transitions, because the Universe lost the high symmetry during its expansion. Important problems of physics and cosmology can be solved if the quarks, leptons, and gauge bosons are composite particles. The dark matter, partially or all consisting of familon-type pseudo-Goldstone bosons with a mass of 10 -5 -10 -3 eV, can be explained in the composite model. Three generations of elementary particles are absolutely necessary in this model. In addition, this model realizes three relativistic phase transitions in a medium of familons at different red shifts, forming a large-scale structure of dark matter that was "repeated" by baryons. We predict the detection of dark matter dynamics, the detection of familons as dark matter particles, and the development of spectroscopy for dark medium due to the probable presence of dark atoms in it. Other viewpoints on the dark components of the Universe are also discussed briefly.

From the Early Universe to the Modern Universe

“…Dark matter particles search in dozens of experiments. The masses of particles constituting the dark matter can lie within the range from 10 −15 to 10 15 GeV, while the cross section for their interaction with nucleons and the cross-section for their annihilation into SM particles can occupy the range 10 −76 -10 −41 cm 2 [46]. Light, weak interacting massive particles (WIMP) search conducts in collaboration CDEX -China Dark Matter Experiment [47].…”

Century of Λ

“…However, after eight years of active studies of the dark energy models another well-known astrophysicist Thanu Padmanabhan answered him by the less optimistic title: "Dark Energy: Mystery of the Millennium" [Padmanabhan 2006]. In my opinion, the present state of understanding of the nature of dark energy is reflected by the title of article by Vladimir Burdyuzha "The Dark Components of the Universe Are Slowly Clarified" [Burdyuzha 2017].…”

Progress in a Vacuum Weight Search Experiment

“…From an experimental point of view, it is important to note that in the recent past the scientific community focused on the possibility of verifying or discarding the various hypotheses by measuring the effects of the gravitational field on a Casimir cavity [16][17][18][19][20][21], in particular by performing a weighing measurement on a rigid Casimir cavity [22][23][24].…”
