 The CMB is a very powerful observable which can be used to rule out or to validate the cosmological models and test fundamental physics. The ITP Cosmology group employed it  for instance to test [[http://arxiv.org/abs/1202.1476|varying fundamental constants]], [[http://inspirehep.net/record/1215575|early dark energy]], [[http://inspirehep.net/record/1122522|coupled dark energy]],  The CMB is a very powerful observable which can be used to rule out or to validate the cosmological models and test fundamental physics.
