Description
A spandex cloth diaphragm forms a gravitational well when a heavy ball is placed at its center, creating a depression that mimics the curvature of spacetime around a massive object. Marbles or coins rolling across the surface follow elliptical, parabolic, or hyperbolic paths depending on their initial conditions. This model visually demonstrates gravitational attraction and the concept of orbits under a central force, illustrating how objects move in response to the curvature created by a mass.
