This isn’t as ridiculous as it sounds and you just need a neutrino-beam… which has a horrible bandwidth plus the ridiculous upfront cost of running two particle-accelerators for a full-duplex link. (Google it up.)
Unfortunately you then get the low bandwidth of the frequencies that can penetrate that much ground

Oh, good point, I recently learned that the speed of light in fiber optics is around 200000 km/s. I always thought physicists were saying “in vacuum” to be technically correct, but that’s actually a huge difference…
