Observations in Cosmology require that dark energy (DE) and dark matter (DM) dominate the dynamics of our Universe. After giving an elementary account of the subject, we focus on a model in
which DM consists of a Bose-Einstein condensate of neutral, extra light, bosons. A possible candidate for these bosons may be yet to be seen Axions. We next show that a simple quantum correction to classical trajectories using the condensate wave function yields a term like the cosmological constant of the right magnitude for DE.
