addle surface
space may be infinite
宇宙膨胀的速度
根据平均的密度
密度临界值若大
宇宙绕行回缩塌
the expansion of the universe
according to the average density
if the critical density is large
bypass the retraction of the universe to collapse
宇宙无论爆炸还是缩塌都是可怕的,如同湍急河流中的漩涡一样,下一个来到时谁也不知道,但是人类目前的地球节奏肯定出了问题,因为地震爆发的频率已经到了历史最高,这或许跟地球的密度遭到破坏有关……
the universe, whether explosion or collapse, is terrible, just like the whirlpool in a swift river, and no one knows when the next one comes, but there must be something wrong with the current rhythm of the earth.b
