Emergence of a Dark Force in Corpuscular Gravity

Understand

We investigate the emergent laws of gravity when Dark Energy and the de Sitter space-time are modelled as a critical Bose-Einstein condensate of a large number of soft gravitons $N_{\rm G}$.

• We argue that this scenario requires the presence of various regimes of gravity in which $N_{\rm G}$ scales in different ways.
• Moreover, the local gravitational interaction affecting baryonic matter can be naturally described in terms of gravitons pulled out from this Dark Energy condensate (DEC).
• We then explain the additional component of the acceleration at galactic scales, commonly attributed to dark matter, as the reaction of the DEC to the presence of baryonic matter.
