1. about 1 billion light-years, 10^25 meters(约10亿光年,10^25米)
Most of space looks as empty as this, the glow of distant galaxies like dotted dust. This emptiness is normal; our own bright home-world is the exception. A tenfold larger view would show no new structure, no new void; the universe is roughly uniform at such dimensions. Novelty on so grand a scale is to be sought over time rather than from place to place. All swift change is in the past. This view will di***owly, for a few billion years at least, as the faint clusters drift still farther apart.
大部分的(宇宙)空间就跟这幅图一般空旷,远处星系发出的光就像点点尘埃。这种空旷是正常的;我们自己的明亮世界除外。比这幅图大十倍的视图不会有新的结构,也没有新的空旷;宇宙在这个尺度上是大致均匀的。在如此大的尺度上,新奇的事物要通过历经时间来寻求,而不是从一个地方到另一个地方。所有的快速变化都在过去。至少再过数十亿年,这个视图会慢慢变得模糊,由于图上模糊的团簇会逐渐飘散(以至于变得更模糊)。
