Visualizing the geometry of spacetime of General Relativity with sector models — •Vassilios Marakis — Universität Hildesheim

Understanding the trajectories of free-falling particles and the path of light in curved spacetime can be challenging, particularly for beginners or those with a casual interest, due to complex mathematics. The sector model simplifies this visualization by dividing the coordinate space into blocks with intuitive Euclidean geometry. Our application enhances this approach by creating sectors based on various metrics, such as the spacetime of the equatorial plane of a massive celestial body, allowing users to explore geodesics and understand phenomena like redshift, light deflection, and perihelion rotation.
