Abstract
We derive the cosmological big bounce scenario from the dipole approximation of loop quantum gravity. We show that a nonsingular evolution takes place for any matter field and that, by considering a massless scalar field as a relational clock for the dynamics, the semiclassical proprieties of a large class of initial states are preserved on the other side of the bounce. This model thus enhances the relation between loop quantum cosmology and the full theory.
