Here, applying the Scale-Symmetric Theory (SST), we present a recapitulation concerning the main formula describing the interactions of the dark-matter (DM) loops with baryonic vortex or stars via the condensates composed of the Einstein-spacetime components. We show that within the same model we can explain very different problems such as the non-gravitational orbital motions of stars outside the bulge of spiral galaxies, different upper limits for radii of accretion discs of black holes, the illusory changes in gravitational constant or the rotation braking of the main-sequence normal stars. We calculated upper limit for mass of single DM loop - it is about 16 powers of ten lower than the mass of electron. Precise maximum mass for DM loop corresponds to the upper limit for frequency 3338 Hz. Intensity for the frequency about 3.34 kHz should be highest. But emphasize that the DM loops are the perfectly elastic structures. Here as well we motivate why the mainstream big bang of the Universe cannot be realized by Nature. The correct big bang, i.e. the inflation and the “soft” big bang of the Universe, is described within SST.
