Description
We present a simple quantum description of the Universe in which the effective de Sitter spacetime geometry emerges from a coherent state of background gravitons. Once localised baryonic matter is added consistently, this quantum state is shown to contain the necessary components to describe MoND phenomenology at galactic scales and possibly explain the tension between values of the Hubble parameter measured from the CMB and supernovae data.
