Interestingly, Zwicky had almost no understanding of why any of this would happen. 有意思的是，兹威基几乎不知道这一切发生的原因。

According to Thorne, "he did not understand the laws of physics well enough to be able to substantiate¹ his ideas. 据索恩说：“他不大懂物理学定律，因此不能证明他的思想。

Zwicky's talent was for big ideas. Others—Baade mostly—were left to do the mathematical sweeping² up. 兹威基的才华是用来考虑大问题的，而收集数据是别人--主要是巴德--的事。”

Zwicky also was the first to recognize that there wasn't nearly enough visible mass in the universe to hold galaxies³ together 兹威基也是第一个认识到，宇宙里的可见物质远远不足以把宇宙连成一片，

and that there must be some other gravitational influence 肯定有某种别的引力影响

what we now call dark matter. 就是我们现在所谓的暗物质。

One thing he failed to see was that if a neutron⁴ star shrank enough it would become so dense⁵ 有一点他没有注意到，即中子星坍缩得很紧，密度很大，

that even light couldn't escape its immense gravitational pull. 连光也无法摆脱它的巨大引力。

You would have a black hole. 这就形成了一个黑洞。

Unfortunately, Zwicky was held in such disdain⁶ by most of his colleagues that his ideas attracted almost no notice. 不幸的是，他的大多数同事都瞧不起他，因此他的思想几乎没有引起注意。

When, five years later, the great Robert Oppenheimer turned his attention to neutron stars in a landmark⁷ paper, 5年以后，当伟大的罗伯特·奥本海默在一篇有划时代意义的论文中把注意力转向中子星的时候，

he made not a single reference to any of Zwicky's work even though Zwicky had been working for years on the same problem in an office just down the hall. 他没有一次提到兹威基的成就，虽然兹威基多年来一直在致力于同一个问题，而且就在走廊那头的办公室里。

Zwicky's deductions⁸ concerning dark matter wouldn't attract serious attention for nearly four decades. 在差不多40年的时间里，兹威基有关暗物质的推论没有引起认真的注意。

We can only assume that he did a lot of pushups in this period. 我们只能认为，他在此期间做了许多俯卧撑。
