黑洞讲明白

一位满脸敬畏的讲解者指向一颗漆黑球体周围旋转发光的吸积盘，球体把周围星光扭曲弯折，宇宙紫与橙交织。深空背景点缀着遥远星系。顶部是巨大标题「黑洞讲明白」，白字配紫罗兰辉光，一支绿箭头弯折着没入事件视界，配一个小小的「为什么？」气泡。明亮的光被戏剧性地弯曲。震撼、电影感，强对比的科学科普氛围。

An awed presenter points at a swirling glowing accretion disk around a pitch-black sphere warping starlight around it, cosmic purples and oranges. Deep space background with distant galaxies. Huge text 'BLACK HOLE EXPLAINED' in white with a violet glow across the top, a green arrow bending into the event horizon and a small 'WHY?' bubble. Bright light bends dramatically. Mind-blowing, cinematic, high-contrast science-explainer energy.
