They'll happen, but very low frequency.

多少还是会发生，但概率极低。

So they broke out a set of very very low frequency speakers.

他们搞出了一套非常非常低频的扬声器。

So this tells us that… the extra bass, these very very low frequencies, caused more moving.

所以这告诉我们，额外的低音，这些非常非常低的频率，引起了更多的律动。

And so that's the superposition or the stacking up of all of these very low frequency gravitational wave signals from the cosmic merger history of supermassive black hole mergers.

它是所有这些超低频引力波信号的叠加或堆积，而它们来自宇宙超大质量黑洞累计合并。

A few navies emit such " very low frequency" (VLF) radio waves for communication with submerged submarines, with the help of antennae hundreds of metres high.

一些国家的海军利用数百米高的天线发射这种“甚低频”（VLF）无线电波，与潜水艇进行通信。

So it's not just one signal, it's something like 100,000, potentially a million merging supermassive black hole binaries all at the same time, creating this, you know, symphony of sound that very low frequencies.

所以，这不仅仅是一个信号，而是 10 万个甚至 100 万个超级黑洞双星同时合并发出的信号，创造出了这首低频交响乐。
