  This report continues recent Peebles-Turner debate "Is cosmology solved?" and
considers the first results for Sandage's program for "Practical cosmology". A
review of conceptual problems of modern cosmological models is given, among
them: the nature of the space expansion; recession velocities of distant
galaxies more than velocity of light; cosmological Friedmann force; continuous
creation of gravitating mass in Friedmann's equation; cosmological pressure is
not able to produce a work; cosmological gravitational frequency shift;
Friedmann-Holtsmark paradox; the problem of the cosmological constant;
Einstein's and Mandelbrot's Cosmological Principles; fractality of observed
galaxy distribution; Sandage's 21st problem: Hubble - de Vaucouleurs paradox;
quantum nature of gravity force.
