But any message carried by these signals would probably be lost because the receivers can't pick up the modulation, or rapid variations, in the base signal.
但是任何携带信息的信号都可能丢失，因为接收者在信号基地不能收集到变调或快速变化的信号。

However, even once scientists are able to measure the modulation, it isn't certain that we'll be able to understand the message.
然而，尽管科学家们可以测量调幅，我们并不确定能够理解这些信息。

Modulation of light refers to changing parameters of light wave such as amplitude, intensity, and phase, frequency, polarization, etc. to make it carry message.
