最初，由于进化以及内部的对立形式，宇宙不太均匀。
At first the universe becomes less uniform as it evolves and objects form within it.
而这些星系的额外的速度，不是由于宇宙的膨胀，而是由于物质在宇宙中的分布不均匀。具体地说，我们的银河系正被附近的仙女座星系和室女座星系团拉扯着。
And these additional velocities that galaxies have that aren't due to the expansion of the universe are due to the uneven distribution of matter in the universe.
彭罗斯博士还预测了另一种不均匀性形态的存在---这就是宇宙“大圈”， “宇宙微波背景辐射”在“大圈”中略显均与性。
Dr Penrose, though, predicts another form of irregularity—great circles in the sky where the microwave background is slightly more uniform than it should be.
