We propose a Curvature Principle to describe the dynamics of interacting universes in a multi-universe scenario and show,
in the context of a simplified model, how interaction drives the cosmological constant of one of the universes toward a vanishingly
small value. We also conjecture on how the proposed Curvature Principle suggests a solution for the entropy paradox of a universe
where the cosmological constant vanishes.
