人眼无法看到无限远,所以我们肉眼能看到的天空是有限的,你可以在晴天站到一个空旷的地方,然后从你的头顶向地平线环视天空,你视线所及的天空只是穹顶的一个局部,就好像太阳只能照亮平地的局部一样, 同理,我们在晚上看到的星空也就是穹顶的一个局部位置的星星的排布,平地固定在穹顶下方,其实我对游星比较有兴趣,它们运动的动力源来自哪里?是否和太阳和月亮的能量来自同一地方?我有个问题:当星星在穹顶旋转时,是穹顶在旋转还是星星在旋转?或者说穹顶是否是固定不动的?穹顶原料是熔融态的玻璃,圆顶的屏幕,星星是否只是从北极中心投射出来的光点,原理类似现在的投影仪。

The human eye cannot see infinity, You can stand in an open place on a clear day and look around the sky from the top of your head to the horizon, the sky you can see is only a part of the dome, just like the sun can only illuminate a part of the flat earth, similarly, the starry sky we see at night is also a local stars of the dome, the flat earth is fixed below the dome, I am very interested in wandering stars, where do they come from the power source of movement? Does it come from the same place as the energy of the sun and moon?and I have some questions:When the stars spin in the dome, is the dome spinning or are the stars spinning?is the dome fixed like flat earth?The dome raw material is molten state of glass, dome screen, whether the stars are just points of light projected from the center of the North Pole, the principle is similar to the current projector?
