Why BrightnessFails by Geometry,Not Distance The phenomenon known as limb darkening has long been treated as a secondary effect. A surface detail to be explained after the primary assumptions of emission, transport and propagation are already in place. In reality, limb darkening is not secondary at all. It is the most precise geometric diagnostic available…

Why “Light” Is NotA Traveling Entity The previous documents established two observational facts that are both simple and decisive. First, the photosphere functions as a boundary of permissibility rather than as a diffusive surface of emission. Second, limb darkening demonstrates that visible manifestation fails by Angle of Encounter, not by distance traveled. Together, these facts…
