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 megaparsec scales. The data allow 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. Thus, abnormal gravity theories must introduce two fine-tuning scales (an inner scale to explain flat…

The detection of cosmic shear on angular scales of up to half a degree is reported using 145,000 galaxies and along three separate lines of sight and it is found that the dark matter is distributed in a manner consistent with either an open universe, or a flat universe that is dominated by a cosmological constant.
