Scientific paper

The work is an attempt to apply Einstein's field equations in the tractable form given by Podurets (1964) and Misner and Sharp (1964) for a spherically symmetric continuous medium, to superdense bodies and hierarchical continuous cosmology. A central question examined is the conditions under which the step-like density profile of a practical hierarchy can be approximated by a smooth function. It is shown that the notion of a semicontinuous hierarchy would not look asymmetric and anisotropic to an observer on the edge of a given system. The discussion considers the application of the Einstein field equations to an extended cosmological medium, showing how the Hubble parameter is defined, how a finite but very small intergalactic pressure is unavoidable, and what time scales and mass-loss rates are expected in the hierarchy. The metric coefficients for any superdense body are derived and applied to determine the baryon number of a superdense object. The dynamical behavior of a superdense body leads to predictions of energy-loss rates and luminosity.
