This is the geometry of a gravitational lens. Light travels from the distant object, but its path is distorted by the gravitational pull of a massive object along the way. An observer sees more than one image of the more distant object.

There are very detailed textbooks on gravity and its role in the universe. However, what’s most important to know about gravity in astronomy is that it influences everything from star formation and galaxy evolution to the orbital mechanics of objects in our solar system to the path that light takes through the universe.
