An ultra-realistic cinematic space scene that visually represents the mysteries and power of black holes. At the center, a massive glowing black hole absorbs surrounding light — its event horizon shining with orange and blue plasma. Around it, stars and galaxies twist and bend, showing how it warps time and space. One side of the image shows a small city-sized black hole, while the other shows a supermassive one millions of times larger than the Sun. In the background, the Milky Way galaxy glows faintly, representing Sagittarius A* at its core. Abstract clock fragments and time warps spiral into the vortex, symbolizing time travel and spacetime distortion. The mood is cosmic, mysterious, and awe-inspiring — perfect for a science fact intro thumbnail."
