Cosmological constant corresponds to the maximally symmetric cosmological term with the equation of state p = −ρ. Introducing a cosmological term with the reduced symmetry, pr = −ρ in the spherically symmetric case, makes cosmological constant intrinsically variable component of a variable cosmological term which describes time-dependent and spatially inhomogeneous vacuum dark energy.

Any cosmological consideration must be based on one or more cosmological principles. Six of them are described namely: The Ancient Hindu, the Ancient Greek, the Genuine Copernican, the Generalized Copernican, the Perfect and the Anthropic Ones. Some cosmological principles have common properties, some are contradictory; some are logically independent, some dependent. Cosmological principles inf...
