Light takes the path of the shortest time given its speed in different mediums it encounters, and this may be longer in total distance than other paths. This is seen in refraction, where the light bends towards the normal of the incident surface when encountering a slower medium. And when it straightens out after leaving the medium at another angle to the normal it must be following its original direction. The of refraction coming and going add to the complement of angle formed by the incident ray and plane of the approached medium. Huygens-Fresnel and Petrology 101. Light refracts around opaque objects, so where it goes in refracting around two such objects is the route of the shortest time as well. The longest route around the first object may make a near miss of the second, so it's faster. How does the second object influence the first? Well, have you ever read Bizarro DC comix? If nature's law were not followed scrupulously we would be living in Bizarro. And we ain't, so what strangely must be, is. And what strangely is, must be. Which obviously leads to this:
