Relativistic Cosmology. I

Key Points

• To establish general theoretical relations in relativistic cosmology and determine whether introducing spatial anisotropy without spin resolves the fundamental difficulties of isotropic models.
• Derived general mathematical and geometric relations within the framework of relativistic cosmology.
• Analyzed cosmological equations modified for spatial anisotropy in the absence of cosmic rotation (spin).
• Demonstrated that introducing anisotropy alone, without including spin, fails to eliminate the outstanding theoretical difficulties present in isotropic cosmological models.
