2--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.
 
1--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?
 
2--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.
 
1--Wow , you're really informative.Thanks a lot.
 
2--You're welcome.

1--太空中的各個(gè)星系都在其間移動(dòng)嗎？
2--不是。它們?cè)谄渌幍目臻g中或多或少的會(huì)有點(diǎn)移動(dòng)，但基本上是保持不動(dòng)的。隨著各星系間的空間不斷擴(kuò)大，各星系聞的距離也在變大。就像一團(tuán)在發(fā)酵膨脹的葡萄干一樣。
1--但我聽說我們的銀河系也許有一天會(huì)和其周圍的星系發(fā)生碰撞。如果各星系都在朝著彼此相反的方向移動(dòng)的話，那怎么會(huì)撞到一起呢？
2--嗯，宇宙是個(gè)混沌之地。某一星系，或一組星系的萬(wàn)有引力可能會(huì)影響其周圍天體的活動(dòng)，使得它們發(fā)生碰撞。但是，總的來看，當(dāng)你比較兩塊足夠大的空間時(shí)，其中一塊申的星系其移動(dòng)方向是遠(yuǎn)離另一塊中的。
1--哇，你可真是見多識(shí)廣了。太感謝了。
2--不用客氣。
