The 20 Khz is obviously NOT an audio tone,

Yes it is. 20 KHz is the highest audible frequency. Humans hear from
20 to 20,000 Hz. No offense but WTF are you thinking??

but exists as VLF, what you
are terming "modulation" is actually a mixing of carriers then ... and
the problem with your question ONLY BEGINS there!

A carrier wave is modulated by the modulator wave. On most AM
stations, the modulator wave consists of the voice of someone
speaking.

Most AM stations have carrier frequencies in the medium wave band - in
the range of 520,000 to 1,160,000 cycles every 1 second.

In the case I am describing, the modulator wave is a 20 KHz pure sine-
wave tone on a carrier frequency of 10^-(1,000,000,000-to-the-
power-10^1,000,000,000) nanocycle every 10^1,000,000,000-to-the-
power-10^1,000,000,000 giga-eons. Is this scenario mathematically-
possible? If not, then why??


No, it's not possible. No planetary system will exist for that span of
time.

Now will you go away?
