以太空探索为主题3分钟口语对话
A:Are the galaxies in the universe moving through space?
A:太空中的各个星系都在其间移动吗?
B:No, the galaxies sit more or less passively in the space
around them. But not too much. As the space between galaxies
expands,it carries the galaxies further apart - like raisms in
an expanding dough.
B:不是。它们在其所处的空间中或多或少的会有点移动，但基本
上是保持不动的。随着各星系间的空间不断扩大，各星系闻的距离也
在变大。就像一团在发酵膨胀的葡萄干一样。
A:But I heard that our Milky way galaxy may one day collide
with a neighboring galaxy. If galaxies are moving apafl from
each other, how can they collide?
A:但我听说我们的银河系也许有一天会和其周围的星系发生碰
撞。如果各星系都在朝着彼此相反的方向移动的话，那怎么会撞到一
起呢?
B:Well, the universe is a chaotic place-and the gravity
from one galaxy, or from a group of galaxies, may disturb the
motion of its near neighbors, causing them to collide. However,
on average, when you compare two large enough chunks of
space,the galaxies in one are moving away from the galaxies in
the other.
B:嗯，宇宙是个混沌之地。某一星系，或一组星系的万有引力可
能会影响其周围天体的活动，使得它们发生碰撞。但是，总的来看，
当你比较两块足够大的空间时，其中一块申的星系其移动方向是远离
另一块中的。
A:Wow , you're really a lot.
A:哇，你可真是见多识广了。太感谢了。
B:You're welcome.
B:不用客气。
