A dark spacetime grid stretches silently across a cosmic void. As a glowing sphere glides through it, the grid bends and ripples around its path, visualizing the curvature of spacetime from Einstein’s General Relativity. Subtle 3D rotation and faint starlight enhance the scene’s depth, revealing gravity as the graceful warping of the universe’s fabric.
