Light bends around heavy objects due to the phenomenon of gravitational lensing, which occurs when the gravitational pull of a massive object, such as a planet, star, or black hole, warps the space-time around it. This warping of space-time causes light rays passing close to the object to be deflected from their original path, resulting in the bending of light around the object. This effect was first predicted by Albert Einstein’s theory of general relativity and has been observed in various ast
