Interactive 3D visualization of a traversable Morris-Thorne wormhole — an Einstein-Rosen bridge stabilized by exotic matter with negative energy density (NEC violation). Features a custom embedding-diagram surface shader with iridescent exotic matter sheen, infalling photon spirals with gravitational blueshift, Hawking radiation particle emission, tidal force vector animation, and a curved spacetime grid. Includes 5 color themes, real-time traversal camera animation, and a procedural Web Audio ambient soundscape (40 Hz drone, sawtooth throat hum, white-noise particle shimmer).
