On the origin of cosmic web
  The emergence of one and two-dimensional configurations -- Zeldovich pancakes
-- progenitors of the observed filaments and clusters and groups of galaxies,
is predicted by means of a developed kinetic approach in analyzing the
evolution of initial density perturbations. The self-consistent gravitational
interaction described by Vlasov-Poisson set of equations with branching
conditions is shown to predict two-dimensional structures as of layers of
increased density and voids between them, i.e. the cellular macro-structure of
the Universe. The modified potential of weak-field General Relativity is
involved, which enables one to explain the Hubble tension, revealing the
conceptual discrepancy in the local galactic flows and the cosmological
expansion. This demonstrates the possible essential role of self-consistent
gravity in the formation of the cosmic web.
