weipingdong blog 读霍金感悟17
宇宙在膨胀
声远弱近强
星系向红移
距离在增长
the expansion of the universe
the sound of distant weak near strong
red shift galaxies distance in growth
站着地球上
感觉如中心
任何方向看
星系都远去
standing on the earth
it feels like the center
look in any direction galaxies away
如同一气球
上边有斑点
充气膨胀时
斑点距离远
like a balloon
top spots
when inflated
spot distance
