WebAug 19, 2013 · Allowing for refraction means that light will curve around the geometrical horizon (Eq. 2), which means that we will see objects that are just beyond the horizon. Using Eq. 2, we will compute a horizon distance that is about 7% further than predicted by Eq. 1. Figure 1 illustrates this point.
