Create a perfectly looping, seamless animation of a rotating black hole. The accretion disk should swirl smoothly around the black hole in a circular, continuous motion. Glowing particles orbit around the center in a hypnotic flow, with subtle flickers of light and occasional tiny pulses of radiation or plasma. No camera movement. Maintain a fixed view, with smooth and balanced motion that loops flawlessly. Use high-contrast lighting with glowing purple tones, realistic space dust, and dynamic lighting to enhance immersion. The animation must feel infinite—no visible start or end.
