托勒密:“地球是宇宙的中心。”哥白尼:“不对,太阳才是宇宙的中心。”伽利略:“是这么回事,我用自制的望远镜看到了。”开普勒:“我还可以告诉你们,行星是沿椭圆形轨道绕太阳运行的。”牛顿:“老开啊,但你知道为什么吗?那是万有引力的缘故。”布鲁诺:“老哥啊,我很信奉你的‘太阳中心说’,但它也有不足,太阳中心不过是宇宙无数星系中的一个,宇宙在时间和空间上都是无限的,没有固定的中心,也没有界限。”
Ptolemy: “The earth is the center of the universe.” Copernicus: “Wrong, the sun is the center of the universe.” Galileo: “This is what happened. I saw it with a homemade telescope.” Kepler: “I can tell you that the planets are orbiting the sun in an elliptical orbit.” “Newton:” “Old open, but do you know why? That’s why gravitation is.” Bruno: “My brother, I believe in your ’Solar Center’, but it also has its disadvantages. The center of the sun is just one of the many galaxies in the universe. The universe is infinite in time and space, there is no fixed center, and there is no limit.”
