弗里德曼的模型
宇宙空间是有限
引力强大空间弯
最后还能回起点
the friedman model space is limited
gravity is so strong the space bending
finally to return to the starting point
一人沿着地球行
障碍不会在前边
更不会从边跌落
人人头上都有天
one along the lines of the earth
barrier not in the front
no more falling from the side
everyone on the head one day
宇宙膨胀又坍缩
弯折力量如漩涡
如果变成马鞍面
空间可能也无限
the universe expands and collapses
bending strength such as whirlpool
if a saddle 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.because the frequency of earthquakes has reached the highest in history， it may have something to do with the destruction of earth's density.m.
