为什么我们不注意到暗物质与暗能量吗?

问:
重子的物质和能量占不到5%的宇宙。其余的“暗物质”和“暗能量”。This is known because galaxies don't follow the known rules of gravitational attraction; they don't fly apart and the equations show that much more (so far invisible) mass is necessary to keep them from doing so. My questions are: How is it that Einstein's (or even Newton's) equations work, even at a local level, if there is so much more hidden mass and energy? Shouldn't the calculations have shown that there was something missing right from the get-go?

答:
在这里,暗物质的密度很低而熟悉的物质密度。同时,我们相信暗物质是均匀分布,而不是集中在恒星和行星。这很大程度上是凸起银河外的平原。所以当地影响金额不多,好像我们周围都是平稳niform分布,不会在任何方向拉。银河,一个更大的规模,你注意到似乎有大肿块向中间的星系。
