Constraints on the Long‐Range Properties of Gravity from Weak Gravitational Lensing

Weak gravitational lensing provides a means of testing the long-range properties of gravity. Current measurements are consistent with standard Newtonian gravity and inconsistent with substantial modifications on Mpc scales. The data allows long range gravity to deviate from a 1/r potential only on scales where standard cosmology would use normal gravity but be dominated by dark matter.
