In de Sitter space with a positive cosmological constant Λ, it is usually said that gravity is smaller than the value given by 1/r2, because Λ *reduces* the attraction of masses at large distances.
However, many people (Verlinde, Milgrom, etc.) argue that a positive Λ *increases* gravitational attraction at large distances. For example, MOND (with its new constant a0) conjectures a higher gravitational attraction than 1/r2 (at large distances).
How can this apparent contrast be resolved?
