The other way to think about it, if I had a flat object then the center of mass would basically be the point where I would need to hold it so it is perfectly balanced.

从另一个角度看，一个平面物体的重心就是,如果在重心处拿起物体，它就能完全地保持平衡。

This unexpected result indicates that the falloff in luminous mass with distance from the center is balanced by an increase in nonluminous mass.

这个意外的结果表明随着远离核心，发光物质逐渐减少，不发光物质逐步增加，最终两者达到了平衡。

If I wished to make the tree more restful and balanced, I could reduce the foliage mass on the left and increase the foliage mass on the right.

如果想使树桩显得更悠闲和平衡，那么可以减少树枝在左面的分布，而增加右侧枝叶的分布。
