摘要: We investigate the evolution of different measures `gravitational entropy' in Bianchi type I and Lemaitre-Tolman universe models. A new quantity behaving accordance with second law thermodynamics is introduced. then go on whether a quantum calculation initial conditions for based upon Wheeler-DeWitt equation supports Penrose's Weyl curvature conjecture, according to which Ricci part dominates over at singularity universe. The theory applied models dust cosmological constant two versions conjecture. First, we local version fails support Thereafter construct non-local entity shows more promising behaviour concerning
