From macroscopic signs of nanodust in space to probable significance of electrodynamics at cosmological length scales

Summary form only given. Plasma phenomena in space were suggested to form the "plasma cables" and, thus, provide long-range electrodynamic bonds. The phenomenon of self-similar skeletal structures, which was identified in the range 10^-5 cm-10²³ cm in the data from various laboratory electric discharges (tokamaks, Z-pinches, plasma foci, laser plumes), severe weather phenomena (tornado, hailstones) and various cosmic space observations, made it reasonable to suggest further extension of substantial role of electrodynamics in the Universe, up to cosmological length scales. The self-similar skeletons were predicted (1998) to be composed of a fractal condensed matter, assembled from self-similar tubular structures, successively forming the "generations" of tubules. At largest lengths, we have the hypothesis for a baryonic skeleton of the Universe (BSU), which has to be in thermal equilibrium with the observed cosmic microwave background radiation. The suggested structure of BSU is based on the already identified and reasonably expected properties of carbon nanotubes, and is favorable for such mechanical and radiation properties of BSU, which make the BSU an alternative to "dark matter" hypotheses stimulated by the difficulties in interpreting fast rotation of the galaxy haloes and fast motion in the galaxy clusters. Here we discuss probable mechanisms of electrodynamic aggregation of magnetized nanodust in space and the respective method of numerical modeling
