We know this because in most globulars, the MOST massive stars are LESS massive than the Sun.

我们之所以知道这一点，是因为在大多数球状星团中，质量最大的恒星质量都比太阳的质量小。

Such collisions are extremely rare in space, but the stars are so tightly packed in globulars that collisions are more common.

这样的碰撞在太空中极为罕见，但球状星团中的恒星非常紧密地聚集在一起，因此碰撞更为常见。

Despite being larger than open clusters, globulars have more stars and are denser, which is one reason they live longer than open clusters.

尽管球状星团比开放星团大，但球状星团拥有更多的恒星，密度也更大，这也是它们比开放星团寿命更长的原因之一。

Most globulars are bigger than open clusters, with diameters perhaps a hundred light years across, though size is a bit hard to measure, since they don't really have an edge.

大多数球状星团都比开放星团大，直径大概有一百万光年，不过尺寸有点难以测量，因为它们并没有真正的边缘。
