Four Dimensional Space vs SkyEngine

Enter a rotating black hole and explore a visual experience beyond the limits of three-dimensional space. This app combines a glowing accretion disk with a conceptual 4D tesseract projected into 3D space, creating a dynamic and immersive visualization. Interact with the scene by adjusting tilt, rotation speed, and gravitational lensing strength to reveal new perspectives and distortions. Watch as the structure shifts and bends under the influence of the black hole’s gravity. No goals — just observe, explore, and experience a different dimension.
