In a world where shadows have mass and can interact with physical objects, Jia and Kofi are standing next to each other outdoors during midday, when the sun is directly overhead. Jia is holding a large, flat, opaque disk above her head. What happens to Kofi's shadow and how might this affect him?
Provide a brief response.
With the sun directly overhead, both Jia and Kofi would normally cast minimal shadows, as their bodies would block the sunlight and create small shadows beneath them. However, since Jia is holding a large, flat, opaque disk above her head, the disk would block additional sunlight, casting its own shadow. Given that in this world shadows have mass, the shadow of the disk would exert a physical force or pressure directly beneath it.

Since Jia is standing next to Kofi, the shadow cast by the disk would partially cover Kofi, depending on its size and the exact proximity of Kofi to Jia. The portion of Kofi's body covered by the disk's shadow would experience the force exerted by the shadow's mass. This could feel like a gentle weight or pressure on that area of his body, akin to a light blanket being draped over him or a light push downward, depending on the mass attributed to the shadow in this magical scenario. The sensation experienced would be exclusive to the areas in the shadow's reach; the rest of Kofi's body would remain unaffected, under normal shadow pressure. If Kofi is sensitive to changes in pressure, he might find this sudden difference between shadowed and non-shadowed areas on his body to be surprising or disconcerting. If the shadow has significant mass, it could also impede Kofi's movements slightly, making it harder for him to lift his arms or move through the covered area, as if he were wading through a denser medium.
