Planar Cosmology is a theoretical framework that describes the universe as a flat, two-dimensional surface rather than a three-dimensional space. This model suggests that all celestial bodies and phenomena exist on a single plane, which can simplify certain aspects of cosmic study. It contrasts with traditional cosmological models that depict the universe as a three-dimensional sphere. In Planar Cosmology, the laws of physics may behave differently due to the unique geometry of the universe. This approach can lead to new insights into the nature of gravity, light, and the overall structure of the cosmos, challenging our understanding of space and time.
