黑洞Black Hole

目前真正可运行的是一个 Schwarzschild 黑洞的零测地线光线追踪实验。它允许改变观察者半径与倾角、吸积盘方向、曝光、视场角、色温和渲染质量。The working piece is a null-geodesic ray-tracing experiment for a Schwarzschild black hole. It lets you change observer radius and inclination, accretion-disk orientation, exposure, field of view, color temperature, and rendering quality.

楞次场坍缩Lenz Field Collapse 是它的前一幕：第七次有效反转后，场会在同一个黑暗画面里坍缩并进入这里。is its preceding movement: after the seventh valid reversal, the field collapses within the same dark frame and enters here.

Doppler 与引力红移可以分别开关。星空、自动轨道和低画质模式也可以独立控制。测地线与偏折几何来自物理模型；吸积盘色温、Bloom、星尘与整体氛围属于电影化处理。Relativistic Doppler effects and gravitational redshift can be toggled separately, as can the star field, automatic orbit, and low-quality mode. Geodesics and deflection geometry come from the physical model; disk color temperature, bloom, stardust, and overall atmosphere are cinematic treatments.

Lenz 定律不会导致黑洞形成。Lenz → Black Hole 只是一段艺术叙事：抵抗变化，随后失稳与坍缩。Lenz's law does not cause black holes. Lenz → Black Hole is an artistic sequence: resistance to change, followed by instability and collapse.

页首的声音开关只生成一层低频 room tone，不加载音频文件，也不把它描述为真实天体声音。The sound control generates only a low-frequency room tone. It loads no audio file and does not present it as the sound of a real celestial body.

源码暂时与实验本身放在同一个 HTML 文件里；这里不另放一个假装完整的代码仓库链接。For now, the source lives in the same HTML file as the experiment; there is no separate link pretending to be a complete code repository.
