Ensemble Average Theory of Gravity

Understand

We put forward the idea that all the theoretically consistent models of gravity have contributions to the observed gravity interaction.

• In this formulation, each model comes with its own Euclidean path-integral weight where general relativity (GR) has automatically the maximum weight in high-curvature regions.
• We employ this idea in the framework of Lovelock models and show that in four dimensions the result is a specific form of the $f(R,G)$ model.
• This specific $f(R,G)$ satisfies the stability conditions and possesses self-accelerating solutions.
