Abstract

The contradiction between observed fractal structure of the large-scale universe and the high-order uniformity of the cosmic microwave background (CMB) radiation could be resolved using the Bak–Paczuski cosmological scenario assuming strong turbulent intermittency of the primordial plasma at the cosmological decoupling transition. Large-scale multiscaling of the dissipation (vorticity) field related to this intermittency implies analogous large-scale multiscaling of the space fluctuations of the CMB radiation. To check this prediction we calculated a full-sky dissipation field of the large-scale CMB fluctuations using the four-year COBE satellite data and found remarkable quantitative correspondence between multiscaling of the large-scale CMB dissipation field and the universal multiscaling of the kinetic energy dissipation (vorticity) field in fluid turbulence. This observation supports the Bak–Paczuski cosmological scenario of formation of the distribution of luminous matter in the large-scale universe after the decoupling transition.
