Einstein's Rings

Einstein's Rings are circular images that occur when a massive object, like a galaxy, aligns closely with a distant light source and an observer. The gravity of the massive object bends and warps the light from the background source, acting like a cosmic lens. When alignment is precise, this lensing effect creates a bright, ring-shaped image of the distant light source. These rings provide evidence for Einstein's theory of general relativity, as they demonstrate how gravity can influence light's path across the universe.
