Interactive application for visualizing 3D and 2+1D spacetime sector models in GR — •Vassilios Marakis — Institut für Physik, Universität Hildesheim, Universitätsplatz 1, 31131 Hildesheim

The movement in spacetime and its curvature are concepts of general relativity, which are not easy to grasp for beginners. An approach to visualizing curved spacetime is the introduction of sector models, which avoids the introduction of the mathematical necessities for a user. The sector model divides the coordinate space into blocks with euclidean geometry, where elemental mathematical knowledge is sufficient to understand the resulting visuals and interpret them qualitatively in the sense of general relativity. The developed application uses different metrics and scenarios like Schwarzschild or space of constant curvature to create these sectors and lets the user construct geodesics in spacetime or calculate curvatures on specific points in space.
