This phenomenon results in the creation of Einstein rings, and it results from the curvature ofspacetime.
The weak version of this phenomenon is decomposed into convergence and shear forms, andvariation in this phenomenon due to orbital motion is called xallarap. This process was observed inSBS 0957+561 A and B, which are identical. Extrasolar planets are detected through one version ofthis phenomenon by the OGLE and MOA projects. This phenomenon creates an angle of 4GM over rc squared, and its observation of this phenomenon in the Bullet Cluster is strong evidence for (*) darkmatter. This phenomenon results in the creation of Einstein rings, and it results from the curvature ofspacetime. For 10 points, name this phenomenon in which beams of light are bent by massive objects.
The weak version of this phenomenon is decomposed into convergence and shear forms, andvariation in this phenomenon due to orbital motion is called xallarap.
