论文摘要
历史上有三个几何化。第一个历史上是由于毕达哥拉斯学校和柏拉图，第二个是来自伽利略，开普勒，笛卡尔和牛顿的，而自然的第三个几何化始于爱因斯坦的一般相对论。在这里，自然的几何化术语是指根据这种构想（其含义不同）在很大程度上使用几何形状来描述。在本文中，我关注第三个几何化，其中黑洞阴影现象将形状与动力学联系起来。结果，时空对称性可以在黑洞物理学中起形式原因的作用。
There have been three geometrizations in history. The first one is historically due to the Pythagorean school and Plato, the second one comes from Galileo, Kepler, Descartes and Newton, and the third geometrization of nature begins with Einstein's general relativity. Here the term geometrization of nature means the conception according to which nature (with its different meanings) is largely described by using geometry. In this article, I focus on the third geometrization, in which the black hole shadow phenomenon relates shape to dynamics. As a consequence, spacetime symmetry could play the role of the formal cause in black hole physics.
