Description
Corpuscular gravity has originated from the observation that a black hole can be viewed as a Bose-Einstein condensate at the critical point, with a large occupation number of (soft off-shell) gravitons and no central singularity. This innovative approach moves away from the semi-classical picture of quantum field theory on curved backgrounds and considers self-gravitating systems as truly quantum. We shall introduce the idea that the gravitational state of the whole Universe can be described as a Cosmological Dark Energy Condensate behaving like a quasi-de Sitter Universe and then discuss the crucial role of regular baryonic matter and the way it interacts with the cosmological condensate.
