Advanced AI discovers a treasure trove of gravitational lenses

Advanced artificial intelligence has identified thousands of possible "gravitational lenses" -- warps in space-time predicted by Albert Einstein -- promising to enhance our understanding of dark matter and the evolution of galaxies. Einstein realized that mass warps space, and massive galaxies and galaxy clusters can distort space around them to such a degree that they form a cosmic lens, bending and magnifying the path of light from more distant galaxies through that warped space. Gravitational lenses are important tools for cosmologists. They can magnify the light of distant galaxies that are too faint to be otherwise seen in detail, or reveal where invisible dark matter is warping space. However, astronomers had only about a hundred good gravitational lenses to use.
