Existence of dark matter (DM) in all space is now the real fact, and reliable study of DM nature and DM properties is an actual task of astrophysics and cosmology. Recently, it was shown by me that observed properties of cosmic microwave background radiation (CMBR) at reasonable assumption, that they are produced by thermal (at 2.7K) DM motion, give materialistic substantiation to conservation laws of classical physics and to all principles of quantum mechanics (as it gives Planck’s constant value). This result confirms the DM existence and shows that CMBR is observed display of DM motion. Also recently, taking into account that creation of electron-positron pairs occurs from DM, the substantiation of positron nature of ball lightning was given by me, what let first explain all its specific properties. At this substantiation it was revealed that “electric field” of positron is a result of nearest DM “polarization” by positron rotation (according to its spin). Revealed physical essence of “electric field” (and “electric charge”) of created from DM “charged” elemental particles (electron, proton and their antiparticles) allowed explain the problem of inexplicably many (more than 350) registered short-living “particles” and their commonly calculated large masses, which are much larger than the masses of stable particles (electron, proton). In addition, such essence of “electric field” let solve old puzzle of the absence of repulsion between protons in atomic nucleus (since in small size of atomic nucleus is not enough DM to produce the “electric fields” of protons) and thus let reveal physical reason of known concept of “strong interaction” (based on unobservable quarks) and also of recent concept of “asymptotic freedom” (based on theoretical treatment only). In this short paper it is shown that understanding of DM existence let also give reasonable materialistic explanation to some other observed fundamental physical properties of the Nature such as: 1) Hubble’s red shift without using concept of Universe expansion, which lead to unaccountable concept of “dark energy”, 2) neutrino physical essence as DM waves, which have different energy and zero rest mass, 3) validity of Boltzmann’s approach for statistical physics since mathematical theorem on non-self-intersection of material body trajectory is not applied for the space filled by DM exhibiting thermal motion, 4) the reason of known failure of Michelson-like experiments at the Earth surface.
