So I want to say to my supporters: When you hear people saying or think to yourself, "if only, or," What if, "I say, please, don't go there."

我要告诉我的支持者：如果你听到别人说，或者你自己曾经这样想，“如果某件事没有发生”，或者“要是出现了另一种情况”……那么我会说，请不要这样设想。

If you stay where you are and you don't move and I move these tuning forks, you will hear a different frequency and that's what we call Doppler effect.

如果我站在这里，你们不移动，我移动这些音叉，那么你们会听到不同，频率，这就是我们，所说的多普勒效应。
