RESOLUTION OF BIG RIP SINGULARITY IN LOOP QUANTUM COSMOLOGY AND BOUNCING SCENARIOS

Loop quantum cosmology provides solutions for classical singularities. Classical singularities are the regions where the space time geodesics cannot extend beyond it. loop quantum cosmology which is derived from loop quantum gravity, resolves all classical singularities. This work attempts to resolve the future strong singularities of cosmic evolution with the help of loop quantum cosmological formalism. Removal of future big rip singularity, using loop quantum cosmology is reported in this work. Final stages of the universe with dark energy dominated conditions are discussed. Interactions of dark matter and dark energy is also reported. New parameter σ is introduced on loop quantum cosmological theories, which determines the fate of singularities.
