时差N小时 假设有一天接收到外星人的信号(下)

（单词翻译）

Scientists would still have enough data to pinpoint¹ where in the sky the transmission is coming from.

科学家们将有足够的数据来确定传输的信号来自太空的哪个位置。

And any slow changes in the broadcast frequency would reveal information about the rotation² and movement of the aliens' planets.

广播频率的任何细微变化都会揭露外星行星旋转和运动的情况。

Okay, but how will we know if they are friendly?

好了，我们如何判断是不是友好的信号呢?

Well, If we ever do detect a transmission, this would be huge news.

如果我们发现了外来广播，那就是个爆炸新闻了。

The government would definitely allocate³ funds to building larger instruments capable of picking up signal modulations.

政府一定会拨款建造更大的仪器来接收信号变调。

However, even once scientists are able to measure the modulation⁴, it isn't certain that we'll be able to understand the message.

然而，即使科学家能够测量变调，也不能确定我们是否能明白这些信息。

I guess everyone's hoping that if the aliens are anything like us, they'll send simple pictures and easy-to-decode messages.

我想每个人都希望外星人与我们多少有点相似之处，他们会发送简单的图画和容易解码的信息。
