問題詳情
It is easy to understand why the Greeks found geocentric cosmology so appealing. Night after night, we see celestial objects moving across the sky from east to west. Wouldn’t it be natural to assume that the Earth lies motionless at the center of the universe and that the Sun, the moon, planets, and stars revolve around it? In the 4th century B.C., Plato postulated a world system with the stationary Earth as its hub and a huge outer space that carried the planets and stars in its daily revolution. But his two-sphere configuration could not account for a particular motion of certain planets. As a rule, the planets and stars traveled together across the sky every night from east to west. But now and then, inexplicably, some planets seemed to drift backwards. Today we know that retrograde motion is an illusion caused by the fact that we observe planetary motion from a planet that is itself in motion. It never entered the mind of Eudoxus, a young contemporary of Plato’s, that the Earth could actually move. But he did try to accommodate planetary retrogression to the motionless earth by developing from the two-sphere Platonic system a model with twenty-seven spheres, one for every known planet; each was attached to another sphere whose rotation, combined with the rotation of the other planetary spheres, explained the “reversed” direction of certain heavenly bodies.

這是很容易理解為什麼希臘人發現了地心宇宙學有吸引力的。夜复一夜，我們看到的天體的天空，從東到西跨越。那豈不是很自然的假設，地球位於宇宙的中心，太陽一動不動，月亮，行星和恆星圍繞它嗎？在公元前4世紀，，柏拉圖假設一個世界的靜止地球系統為樞紐，和一個巨大的太空進行的行星和恆星在其日常的革命。但他的兩個領域配置無法解釋某些行星的運動。作為一項規則，恆星和行星在天空中一起走過，每天晚上從東到西。但現在，然後，莫名其妙地，一些行星似乎向後漂移。今天，我們知道，逆行是我們觀察到的事實，從一個星球，本身就是在運動的行星運動所造成的一種錯覺。它從來沒有進入歐多克斯的頭腦，一個年輕的當代柏拉圖的，，地球實際上可以移動的。但是，他並嘗試以容納行星倒退一動不動地通過從雙球柏拉圖的系統開發的模型與27球，一個為每一個已知的行星，每個被連接到另一個球體的旋轉，旋轉的結合其他行星的領域，解釋了“反”方向的某些天體。46根據希臘的宇宙觀，下列哪個是沒有移動的？ （A）地球（B）月球（C）火星（D）太陽<google
