Create an ultra-realistic illustration of a black hole, centered in the image, with the background set to a deep, solid black color (hex #000000). The event horizon of the black hole should be surrounded by vibrant particles, with two distinct color sets: bright neon green particles (hex #00FF87) and cool cyan-blue particles (hex #60EFFF). The particles should swirl and bend around the black hole, following the curvature of space-time, with a dynamic and energetic appearance. The illustration should emphasize the intense gravitational pull of the black hole, with the particles appearing to stretch and blur as they approach the event horizon. Ensure the overall composition is highly detailed, with a focus on realism, capturing the complex interplay of light, color, and gravitational forces. The contrast between the black background and the vibrant particles should make the image visually striking and immersive.
