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…
Send it through the earth, you can reduce it theoretically to 42.5ms
This isn’t as ridiculous as it sounds and you just need a neutrino-beam… which has a horrible bandwidth (of 0.1 bits/s) plus the ridiculous upfront cost of running two particle-accelerators for a full-duplex link. (Google it up, this exists.)
