16、an idea.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。They believed God had made the world and for that reason the earth was special and must be the centre of the solar system.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。The problem arose because astronomers had noticed that some planets in the sky seemed to stop, move backward and then go forwar
