16、 showing the solar system with the Sun at its centre,COPERNICUS REVOLUTIONARY THEORY 哥白尼的革命性理论 尼古拉哥白尼被吓得心烦意乱的。虽然他曾经试着不去理睬那些数字，然而他所有的数学计算都得出了一个相同的结论：地球不是太阳系的中心。只有当你把太阳放在中心位置上，天空中其他行星的运动才能说得清楚。他的这个理论可不能告诉任何人，因为即使他只暗示有这种想法，他都会受到强大的基督教会势力的惩罚。教会认为世界是上帝创造的，正因为如此，地球就具有特殊的意义，它必定要成为太阳系的中心。,这样，问题就来了，因为天文学家以前发

17、现过，天上有些行星停顿下来，往后移动，然后再成环状向前移动，而其他行星看上去有时亮些，有时又不怎么亮。如果地球是太阳系的中心，而所有行星环绕着地球转的话，那么这种现象就很奇怪了。 哥白尼对这些问题曾经苦苦思索过很久，试图找出问题的答案。他曾经收集过观察星球的数据，并且利用他的全部数学知识来解释这些数据。但是只有他的新理论才能作出解释。于是，他在1510至1514年期间从事这项研究，逐步修改他的理论，直到他感到完善时为止。,1514年，他把他的新理论私下里给他的朋友们看。他对旧理论的修改是具有革命性的。他把太阳固定在太阳系的中心位置上，而行星则围绕着太阳转，只有月球仍然绕着地球转。他还提出地球在

18、围绕太阳转的同时，它本身还自转，这样就说明了行星运动的变化情况以及星球亮度问题。他的朋友都热情地鼓励他把他的想法公之于世，而他却小心谨慎，他不想遭到基督教会的攻击，所以他直到1543年临终之前才公布了这一观点。,当然，他小心谨慎是对的。基督教会拒绝接受他的理论，说这种理论违背了上帝的旨意，而支持这种理论的人都会受到打击。然而哥白尼的理论却是我们宇宙观赖以建立的基础。他的理论还改变了基督教对地心引力的看法，他们认为物体往地球上掉落是因为上帝创造了地球，而地球正是宇宙的中心。哥白尼表明这是明显错误的。如今人们可以看到，他的这些想法与艾萨克牛顿、阿尔伯特爱因斯坦以及斯蒂芬霍金等人的研究都有着直接的联
