If the center of NGC 4258 were a star cluster, the stars would be so closely spaced that collisions between individual stars would have long ago torn the cluster apart.

如果 NGC 4258 的中心是一个星团，恒星之间的距离会非常近，以至于在很久以前单个恒星之间的碰撞就会把星团撕裂。

And as you go to higher and higher levels, those energy levels, as you saw in the case of hydrogen, are more closely spaced.

当能级变得越来越高，那些高能级的轨道，就会变得越来越接近，正像你在氢原子里看到的那样。

And so when they become very, very closely spaced there is mutual repulsion of those electrons.

所以当它们越来越近的时候,这些电子会产生相互的排斥力。
