A gravitational lens is a distribution of matter (such as a cluster of galaxies) between a distant light source and an observer that is capable of bending the light from the source as the light travels toward the observer. This effect is known as gravitational lensing, and the amount of bending is one of the predictions of Albert Einstein's general theory of relativity. Treating light as cor… WebGravitational Lensing The Vera C. Rubin Observatory will soon discover thousands of gravitationally-lensed quasars, each split into multiple images, as their light reaches us via separate paths through curved spacetime.
