Description

We present a simple quantum description of black holes and the late Universe in which the effective Schwarzschild-de Sitter spacetime geometry emerges from a coherent state of background gravitons. Once localised baryonic matter is added consistently, such quantum states are shown to describe regular black holes and to contain the necessary components to describe MoND phenomenology at galactic scales. The tension between values of the Hubble parameter measured from the CMB and supernovae data can also be addressed with this approach.
