"The Shadow That Never Moves: A Study of Light Bending and Parallel Geodesics in Wormhole Physics"

This study investigates the condition under which an object’s shadow length remains constant regardless of the Sun’s position or movement. We explore whether such a phenomenon could naturally exist on Earth and conclude that, under normal circumstances, shadows change in length due to the varying angles of incoming light. However, through relativistic analysis, we determine that if an object is placed inside a wormhole or a symmetric gravity well, the curvature of space-time forces all incoming light rays to align in parallel, leading to a permanently fixed shadow length (L). This insight reveals a unique gravitational property that has not been previously explored in terms of shadow behavior.
