dome theory

Dome theory suggests that the earth’s surface can be likened to a curved, dome-shaped structure. This means that the land and oceans follow a curved, arching pattern rather than a flat plane. In this model, the horizon appears curved because we are viewing the earth's surface as part of a large, enclosed dome. Proponents believe this explains phenomena like the curvature of the horizon and the way ships disappear from view bottom-first. While mainstream science supports a spherical Earth, dome theory offers an alternative perspective focusing on a curved, enclosed environment.
