Gravitational lensing formalism — In general relativity, a point mass deflects a light ray with impact parameter b by an angle hat{alpha} = frac{4GM}{c^2b}. A naïve application of Newtonian gravity can yield exactly half this value, where the light ray is assumed as a massed… … Wikipedia
Weak gravitational lensing — While the presence of any mass bends the path of light passing near it, this effect rarely produces the giant arcs and multiple images associated with strong gravitational lensing. Most lines of sight in the universe are thoroughly in the weak… … Wikipedia
